ICO is one of the important applications of virtual currency. It solves the opportunities for market capital to participate in projects or early investment of enterprises by avoiding legal supervision. ICO is full of opportunities. If you choose a reliable ICO project, it may be an opportunity for a sharp increase in assets. This opportunity may not be many, but it is still much more than traditional industries; ICO is also full of challenges. It may be normal for most ICO projects to fail to achieve the expected success. Not a few break after ICO in the market. Inadvertently participating in a project with pits is also a distressing loss.

Imtoken wallet EOS mapping tutorial

preface
Many coin circle friends have used imtoken wallets. This article tells you how to complete EOS one click mapping through imtoken. The current EOS is a token based on Ethereum erc-20. After the EOS master network is started, it needs to be converted into a real token on the EOS master network. Therefore, this conversion operation needs to be completed through mapping. As long as there are more EOS after mapping, it will be a valid EOS token after 6.2 is on the master network.
Not much to say, let's take you to complete the one click mapping of EOS. (some screenshots are from imtoken tutorial)
Step 1: open imtoken wallet and click Find - > candy bar
Step 2: click EOS mapping
Here you will check whether your wallet has EOS and whether it has been mapped. If you have EOS in your wallet and have not been mapped, you will be prompted to map immediately. When you click map now, the public key and private key of EOS wallet will be generated for you. Note that the private key must be backed up safely. It is best to copy it on paper (note that it is case sensitive in English). Do not take screenshots or transmit and store it through the network. Keep the private key confidential and don't let it out.
After backing up the private key, click "I have confirmed and keep it properly"
Step 3: enter the private key just backed up in the input box for secondary verification
After the input is correct, click the read precautions & mapping, and then a pop-up window will appear. You need to pay a small amount of eth as the miner's fee. Click OK to complete the mapping. After confirmation and waiting for the miner to confirm the transaction (this process takes about 10 minutes), the EOS mapping is completed.
Pending confirmation of transaction
Mapping succeeded
summary
Although most exchanges will help you do EOS mapping, it is recommended to do it yourself. The reasons are as follows: first, there are some candies dropped by air. The exchange will not give them to you. You can get them in your wallet; Second, you can exercise your voting rights (if you want EOS to develop better, you'd better use this right reasonably).

How to import wallet?
Imtoken 2.0 introduces the concept of digital identity. Digital identity is not the identity of real name authentication, but your digital identity in the blockchain world.
When using imtoken 2.0, users must use mnemonics to generate a digital identity. If you have not backed up mnemonics before, or if you are using a decentralized wallet for the first time, you can click create identity.
If you have backed up mnemonics before, you can use the identity recovery function to import mnemonics to generate digital identity.
So how to import the wallet under the current digital identity?
Here, take importing bitcoin mnemonics as an example:
1. Click the pull-down switch wallet button at the top of the 'wallet' home page, and click the '+' button on the right side of the 'imported wallet'
2. Enter the 'select wallet type' interface, click 'bitcoin wallet', and enter the 'import bitcoin wallet' interface
3. Select 'mnemonic words', enter mnemonic words in the input box (each mnemonic word is separated by a space), enter the wallet password, and select whether it is an isolated wallet address
Note: one thing to note here is that when selecting the address type, select 'isolation witness' or' ordinary wallet '. The isolation witness wallet is the BTC address starting with 3, while the ordinary wallet is the BTC address starting with 1.

How can imtoken users easily and quickly change their wallet password? Imtoken wallet (Ethereum wallet) is your necessary software in the coin circle. All tokens sent based on Ethereum (ETH) can be used to receive or transfer money. If you want to hold your currency for a long time without trading, or feel that the exchange is unsafe, you can mention it in your imtoken wallet.

In the decentralized wallet imtoken wallet, the authentication contents of all users, such as transaction password, private key and mnemonic words, are saved locally on the user's mobile phone and not in the centralized server. Therefore, the user forgets the password and cannot be reset through a third-party organization (such as imtoken team).
In imtoken 1.0, reset password tutorial: "I" - "manage wallet" - "select wallet to modify" - "modify password" - "import now" - "mnemonics / private key"
In imtoken 2.0, if "identity password is forgotten", you can only "reinstall app and import identity mnemonics" to reset the password. If "the imported wallet password is forgotten", reset the password tutorial: "click the drop-down button to open the wallet list" - "imported wallet" + "-" select the imported wallet type "-" enter the wallet mnemonic or private key and set a new password "-" prompt that the wallet already exists and click OK "
If you don't save the private key or mnemonic words, you can't reset the password. You can only try to find it through careful reflection.

Sometimes when we use imtoken wallet, it is likely that it will be deleted inadvertently, or the mobile phone is stolen, or the mobile phone cannot be turned on

that
At this time, how can we repair the previous wallet after changing the new machine? After all, if there is property in the wallet, let's teach you how to restore the true identity of imtoken wallet. Naturally, what we must pay special attention to here is that the premise is that you must remember your mnemonic words well, otherwise you don't have to think about it.
imToken2. 0 International Edition has introduced the effect of Multi Chain Wallet. In order to better facilitate, fast, efficient customers and improve their wallet with safety factor, we have adopted the definition of "creating real identity". In this way, customers can manage the Multi Chain Wallet under a real identity. The original text mainly explains the whole process of repairing the real identity of imtoken wallet data information.
Imtoken wallet official website: https://imtkoen.im Introduction to wallet repair and real identity graphics
1. Click the "repair real identity" function button on the start page of imtoken wallet to repair the real identity. How to restore the real identity after the imtoken wallet is unloaded? Can forgetting mnemonics be repaired?
2. Click "repair real identity", open "I have read carefully and want the above terms", and click "again" to choose. Enter mnemonic words into the box. It should be noted that after importing imtoken wallet mnemonics, you can not easily be disciplined by the user name and password set in the past, and set a new user name and password again. This is why "mnemonic words" are hard for us.
How to restore the real identity after the imtoken wallet is unloaded? Can forgetting mnemonics be repaired?
3. After setting imtoken wallet user name and password and typing transaction password message reminder. You can click the "repair real identity" function button. Then the current status will be repaired successfully. Here's an important hint. Forgetting mnemonics is no way to repair the real identity of imtoken wallet. Therefore, we should remember mnemonics well in the case of establishment.

Every transfer on Ethereum must pay a certain amount of Ethereum as the miner's fee. Our daily transfer fee of 0.001 eth is enough.

But on June 10, Ethereum address 0xcd On 182d, there was a transfer with a handling fee of 10668.73185 eth, and the transfer amount was only 0.55 eth, less than one ten thousandth of the handling fee. Just when we thought it was a big family who slipped and set the handling fee incorrectly, the Ethereum address sent another transfer with a handling fee of 10668.73185 eth, which was 350 eth this time.
The reason for these two abnormal transfers is unknown. At present, the community speculates that there may be a bug in the transfer program, or the owner of the Ethereum address may have been blackmailed by hackers in disguise.
In fact, this is not the first time that Ethereum has seen sky high miners' fees. As early as 2019, there was a transaction with a handling fee of up to 2100 eth on the Ethereum chain, and the transfer amount was only 0.1 eth.
When we use imtoken, will we slip our hands for a moment and set the transaction handling fee higher than the transfer amount?
Third gear miner fee
The answer is that the possibility exists, but the probability is very small.
The Ethereum transfer interface of imtoken is as follows. We can click the miner fee to set it.
The latest version of 2.5.7 imtoken wallet supports three levels of miner fees, "fast, average and slow". We can choose the time when the transaction is confirmed and packaged according to the needs, and there will be no case that the manual slide is set to the sky high miner fee.
You can see that there is a number under each level of miner's fee speed in the picture, namely "31.00 Gwei, 27.00 Gwei and 24.00 Gwei". Everyone knows the number, but this unit Gwei is a little confusing.
Emmm ~ the unit of GB is familiar to everyone. The size of videos we usually watch is usually between 1-2 GB. GB is the abbreviation of gigabyte, which is the unit of computer to measure the size of information. Gwei just replaced byte with Wei, and became the unit to measure eth on Ethereum blockchain.
The RMB has yuan cents per cent. The yuan is the most commonly used and the largest unit of measurement in our daily life. Similarly, as a digital asset, Ethereum also has unit sizes. The largest is eth, the smallest is Wei, and the middle is Gwei. The conversion relationship between the three is as follows:
1 eth = 1000000000 Gwei (9 zeros after 1)
1 Gwei = 1000000000 Wei (9 zeros after 1)
1 eth = 10000000000000000000000 Wei (18 zeros after 1)
Now that we understand that Gwei is a unit for measuring ether, let's take a look at the following calculation formula in the line of "miner's fee"
Gas Price（27.00 GWEI）*Gas（60,000）
Regardless of the specific meaning of gas price and gas, let's take the number in brackets to calculate, 27 * 60000 = 1620000, plus the unit is 1620000 Gwei. According to the conversion relationship between Eth and Gwei listed above, 1620000 Gwei is equal to 0.00162 eth, which is the amount of miner's fee we pay.
Gas and gas price
Gas is translated into Chinese, which means gasoline. Gas price is the price of gasoline.
We can imagine an Ethereum transaction in which the sender transfers a certain amount of Ethereum to the receiver as driving a car from home to the company. The cost of the journey is the gas consumed by multiplying the gas price per liter of gasoline by the gas price.
Every section of the road that the car travels consumes gasoline. Every transfer on Ethereum consumes gas. The cost calculation of the transfer is the same as that of the car:
Gas price * gas
27.00 Gwei is the gasoline price of Ethereum; 60000 is the amount of gasoline consumed.
In real life, the price of gasoline is affected by the relationship between supply and demand, which is not invariable, but will fluctuate constantly. The gas price on Ethereum is also affected by the degree of transaction congestion on this blockchain and will change. When the more transactions waiting for miners to confirm on Ethereum, the gas price will rise. Imtoken's "three gear variable speed" miner fee is calculated by capturing the transaction congestion information on the Ethereum chain in real time, so the gasoline price of these three gears is also changing.
The "fast, average and slow" three block transactions correspond to "31.00 Gwei, 27.00 Gwei and 24.00 Gwei" respectively. It may become "26.00 Gwei, 21.20 Gwei and 19.10 Gwei" in a few hours.
Back to the initial question, will we slip when using imtoken, and the set transaction handling fee is higher than the transfer amount? If we use three gear transmission, it won't, but if we choose Custom mode, it's possible.
When we choose to customize, we can freely set the gas price to the sky high price. For example, if I set the gas price to 200000000 Gwei, the miner's fee I need to pay is 12000 eth, but a prompt "too high gas price will cause waste of miner's fee" will pop up under the gas price, which reminds us that the handling fee is set too high, It needs to be lowered.
Therefore, if you use imtoken to transfer money, on the one hand, the "three gear speed change" function will provide you with the most appropriate option; On the other hand, imtoken will also provide friendly tips when the miner fee you set is "unreasonable".

With the wave after wave of wealth waves such as bitcoin, dog coin and defi coin, more and more investors pay attention to the investment value of the digital money market. Although no one knows the value and future of digital currency, the myth of wealth creation of blockchain currency stimulates the nerves of every investor... After all, the value of digital currency exists objectively, and valuable currency needs a place to store, and the digital currency package is the place to place digital assets. What are the mainstream digital currency wallets on the market today? To solve this problem, Xiaobian reviewed the world's most mainstream decentralized digital currency wallet in 2021 for investors' reference.
1、 Metamask Wallet
Metamask is an open source Ethereum wallet, which can help users easily manage their Ethereum digital assets. The little fox metamask wallet is the best Ethereum asset management wallet in the world. It can be used for the management of Eth and tokens, as well as the interaction of DAPP applications such as one click coin issuance. Because of its convenient and concise user experience, it has a wide user base in Europe, America and other countries, and is highly praised and influential. It is also one of the digital wallets highly recommended by Xiaobian.
2、 Imtoken Wallet
Imtoken is easy to use and has medium security. It belongs to mobile wallet
Imtoken wallet, as a professional digital asset wallet, is safe, safe and easy to use; Support multi chain and multi currency management and exchange, so that blockchain technology can be better integrated into your life. Imtoken's vision is to align economic incentives, make privacy inviolable and let value flow freely.
Imtoken has recently received a round a investment of US $10 million from IDG capital. Imtoken founder and CEO He Bin said that this round of financing will support the development of imtoken's overseas market and the reserve of more technical talents. As a digital wallet product developed by companies in China, the use experience of imtoken is undoubtedly in line with the habits of Chinese people, and it is also one of the digital wallets most used by domestic users.
3、 Trust Wallet
As the official website wallet of coin security exchange, trust wallet provides users with a safe and convenient choice to deposit funds outside the exchange, and a variety of built-in functions further enrich the experience of using encrypted assets. It can be used with any erc20, erc223 and erc721 tokens. Trust wallet also supports the main blockchains in the Ethereum ecosystem - Ethereum, Ethereum classic and Callisto. At present, more than 20000 tokens built based on Ethereum can be accessed through the trust wallet application

Transfer eth is the currency not received:

First of all, it is necessary to confirm whether the exchange has transferred out the token. The operation method is to go there https://etherscan.io Check whether there is a record of transfer in token at the receiving address. If there is no transfer in record on the chain, it indicates that the exchange has not carried out currency withdrawal. Please contact the customer service of the exchange for handling. (sometimes the exchange shows that the withdrawal is successful, but there is no record on the chain. Everything is subject to the data on the chain. If there is no record on the chain, even if the exchange has not transferred out, contact the customer service of the exchange for assistance)
If in https://etherscan.io The query and withdrawal of currency on the has been successful, but the token is not displayed in imtoken. You can add tokens by searching the token name or the token contract address.
Search for the token name and add steps: click the asset home page + button - > input box at the top of the asset management page - > enter the token name - > add the token you need and turn on the token switch, and then return to the asset home page to refresh the asset
Steps to add a search contract address: click the asset home page + button - > input box at the top of the asset management page - > enter the contract address - > add the token you need and turn on the token switch, then return to the asset home page and refresh the asset

Digital currency asset transfer is a problem that all coin friends will face. Many people have encountered all kinds of problems in the process of storing and using digital currency wallet transfer. The history of blood and tears drawn by predecessors with their experience is enough to become a safe haven classic. In order not to let everyone repeat the mistakes, today we will talk about the problems and solutions that will be encountered in using digital currency wallet.

1、 Storage of wallet private key:
When you register your wallet, although the system software will remind you to keep the private key, some people still forget to back up the private key and cause the coin to disappear. Recently, something happened around me. A coin friend didn't keep his wallet private key, resulting in the loss of 200000 EDS played by the project party. Therefore, it is still necessary to take out the storage of the private key and talk about it with you.
Personally, I think the best way is to write the private key in a paper notebook and save it. In this way, we can eliminate the damage caused by all network connections and will not cause direct economic losses due to the intrusion or theft of the computer system. When writing, you need to double check to ensure that the private key is copied correctly. If you don't mind, you can take photos of the private key with the camera and save it. In this way, both sides are prepared to ensure the safety of funds. Please be sure to use a good notebook and a USB flash disk with quality assurance when recording.
2、 Wrong input address:
Commonly used wallets include bitcoin wallet, imtoken, atoken, etc. here, take imtoken wallet as an example. It can only store the currency issued based on Ethereum public chain, so the currency stored in the wallet is basically based on the currency issued by Ethereum. Since different currencies belong to different public chains, bitcoin, Wright coin and Ethereum cannot use wallets with the same address.
Note: for bitpie wallet, the address corresponding to each coin is the same, and the same wallet can generate multiple collection addresses. The imtoken contains the same wallet address.
There is another special case - mapping. Many projects temporarily use the Ethereum public chain to distribute projects. Until their own public chain is completed, they will move to the past. They can change money and map. Taking EOS as the representative, because it is famous and supported by BM, both exchanges and wallet service providers take the initiative to provide mapping, but many less famous currencies do not enjoy such treatment and need to be replaced by themselves, resulting in asset losses.
In fact, most people will deposit their assets in the exchange, which will be more convenient and low-cost. After all, if you put it in your wallet and transfer it in and out, you have to pay a certain miner's fee.
3、 Asset transfer:
In a transaction, if you want to transfer money to someone else's wallet, you need to pay attention to several points. First of all, you need to check the wallet address. If the address is wrong, others will not receive the money, and there will be the risk of losing the money.
● if the safest way is to completely off-line transmission, but everyone may not operate like that. After all, it's really troublesome. In the process of currency printing, I also transmit through the network, as long as I ensure safety.
For example, in the transaction, we need to make money. After copying the other party's address, there will be some security risks through copying and pasting or wechat transmission. In this process, we need to re check whether the other party's address and their input are correct, so as to ensure that the address will not be tampered with by the Trojan horse.
● note that as long as you open the website of the exchange and other website pages at the same time, your transaction may be tampered with by the potential script in the website and sold at a very low price. In order to ensure the security of assets, it is best to recreate the wallet and establish multiple accounts every time the private key is transmitted. This is a management method that will not cause losses to all assets.
4、 Wallet status conflict:
Some people will encounter conflicts in the status of virtual currency e-wallet during operation, and the rushed currency cannot reach the account. If the money charged cannot reach the account, you need to find the operation team to solve it. It is difficult for you to solve this problem. Now the mainstream digital currency is optimized well, which rarely happens.
5、 Wallet address storage:
The wallet address should not be stored in the mobile phone to prevent it from being invaded and stolen by trojan virus. Improper use of mobile phones, such as the leakage of unsafe assets caused by downloading virus carrying software or connecting to public WiFi, has also caused a lot of losses. Therefore, whether it is transaction transfer or daily use of mobile phone. Be sure to avoid the source of unsafe factors. In particular, do not log in to public WiFi at will, and do not cause unnecessary losses due to small losses.
In addition to the above, the withdrawal of personal e-wallet sometimes shows that it cannot be received. This may be due to the channel or network, but it will arrive later. Because digital currency transactions are irreversible, there is generally no possibility of returning to the original way. Therefore, in this operation, it is best to synchronize the E-wallet.
In addition, some Neo wallets can't check the balance after coin printing, but they have actually arrived. This is mainly because the wallet doesn't add hash script. You can contact the project party or directly enter your Neo wallet address in the Neo blockchain browser if you feel troublesome

Two types of wallet addresses are supported: ordinary btimtoken address and wigtoken address.

When importing bitcoin wallet, you can select the imported address type. After importing the wallet, you can also switch the address type according to the actual use needs.
So, how does imtoken's bitcoin wallet switch address types?
Operation steps
1. Open imtoken, enter the bitcoin wallet asset page, and click "..." at the top right of the page Button to enter the wallet management interface
2. Click "switch address type"
3. Select "normal" and enter the wallet password to switch to the normal address beginning with 1; If you select "isolation verification", you can switch to the isolation verification address starting with 3 after entering the wallet password
be careful:
1. The transfer fee of isolated witness address is less than that of ordinary address.
2. The assets of ordinary address and isolated witness address are not interconnected. If you want to transfer assets, you can send transfer.

The usdt on huocoin online cannot be transferred to imtoken wallet. Because imtoken does not support usdt bitcoin wallet support.

Based on the BTC block network, usdt can operate and withdraw money normally, depending on whether the other platform supports receiving. Invalid because the imtoken wallet is not connected to the usdt.
Usdt can go to bitpie. However, it is generally not recommended to keep usdt for a long time.
Imtoken wallet is an exclusive Ethereum wallet, which can only be used as a token for storing Ethereum. Usdt TEDA coins are exchanged with us dollars, 1usdt = US $1.
Extended data:
The usdt TEDA coin purchased on Huo coin online needs to make a transfer action, transfer the currency of the legal currency account to the trading account, and then the channel button of withdrawal will appear below the usdt ratio. If there is no transfer, the button of withdrawal will not appear. Then you can see if the wallet platform imtoken can receive this coin. You can help find the answer inside.
Then, it is normal to transfer the usdt on Huo coin online into imtoken. If imtoken does not support it, just find another wallet that can support the deposit of usdt coins.
Advantages of huocoin network:
1. Safe and reliable, easy to use, and the product user experience is particularly friendly.
2, support OTC legal tender transactions, support WeChat, Alipay and bank card transfer.
3. The application for registration is simple, with more currencies and large trading volume, which is convenient for trading at any time.

Imtoken wallet is recommended this time, which is more convenient to create and use than other wallets.

1、 Download and install
Android:
1. Go to http://token.im Download upgrade
2. Do not use the mobile phone after the root
3. Do not use deep cleaning to delete mobile phone files casually. Deep cleaning of some Android phones will delete some important files in the mobile phone
IOS:
1. to APPStore download upgrade (non Chinese mainland)
2. Do not arbitrarily use the appid provided by a third party, such as the appid purchased from Taobao store
3. Don't start icloud cloud backup at will, because if you use the wrong backup method, such as storing mnemonic screenshots or recording them in a memo, it is likely to be synchronized to icloud
2、 Create Wallet
After installation, when you open the app for the first time, an interface (as shown in the following figure) will appear. To create and import an Ethereum wallet, click Create wallet, fill in the wallet name and password according to the system prompt, and you can create it successfully
Warm tip: the password created here will be used to encrypt and protect the private key, which is used for transfer. Therefore, it is necessary to set the password. The combination of upper and lower case letters, numbers and symbols is really necessary and must be remembered. Those who can't remember can take a book to remember
Special note: for the text in the yellow background in the figure below, because the virtual currency wallet cannot retrieve the password for security enhancement, remember the password when moving! Remember the password! Remember the password! Important things are to be repeated for 3 times!
3. Back up your wallet
This is a very important link. You must back it up. Don't be lazy. You won't be responsible for the loss of assets, because if you unload the wallet carelessly, you won't be able to find it back!
Imtoken supports backup mnemonics and keysore files. After exporting, you must properly protect the backup information, especially mnemonics. Once leaked, it is equivalent to others owning your assets. In addition, you must remember your password to create the wallet. Once you forget the password, you can't unlock keysore, which means you can't trade!
Note keysore, you need to enter the password before exporting the file. Some small partners export empty files through cloud notebooks and can use email, while others bring their own "note" tool through their mobile phones.
The exported file is as follows:
After the above settings are completed, you can enter your wallet. Click a string of codes under the name of the wallet to generate your collection address, just like the bank account, so that others can transfer money to you through this address.
The above is how to create a wallet and get the wallet address

You can directly add usdt contracts in the trc20 chain, add trc20 wallets, and then add usdt smart contracts.

Similarly, you need to go to the usdt address of trc20, but you need to use TRX as the energy fee, so you need to charge 10 TRX to the trc20 address holding the usdt. It may be more, but it's safe.
Does the transfer from imtoken to imtoken need to deduct the handling fee
Wallet transfers such as bitcoin and Ethereum need to pay miners' fees, but miners' fees exist in different forms; In addition, it should be noted that the transfer of wave field wallet and EOS wallet does not need to consume miners' fees, but it needs bandwidth and energy. The transfer of EOS account will consume CPU and net, and all the consumed CPU and net will be returned to your account over time. Here, take the transfer of usdt in eth wallet as an example, The usdt in the ETH wallet needs to consume eth as the transfer fee.

I withdrew money from XX exchange to imtoken wallet. Why didn't I get it?

I asked the customer service of the exchange and they said that the transaction had been successful, but it was not displayed in imtoken wallet.
Recently, many exchanges have launched their own public chains. You will find that there are more network channels to choose when withdrawing money. If you are not careful, the above will happen: point_ up_ 2: This problem.
Take the usdt withdrawal of Huo coin exchange as an example, you will see four withdrawal options and the corresponding handling charges:
Erc20, service charge 10 usdt
Trc20, handling charge 1 usdt
Heco, handling fee 0.09 usdt
Omni, service charge 28 usdt
Obviously, among the above options, the handling charge of heco coin collection network is the lowest. Therefore, many users will choose this network, enter the ETH wallet address in their imtoken wallet into the coin collection address, click OK to withdraw the coin, and then wait for the light
As a result, I waited for a long time and found that I still couldn't receive the money in my wallet. The reason is that you chose the wrong network when withdrawing money, but don't worry. Imtoken's user-defined node function can help you retrieve the mistransferred tokens.
Retrieve mistransferred tokens
Click "Ethereum mainnet" at the top of the wallet asset page and select the channel when you withdraw money in the "node switching" list.
Take the three major exchanges as an example. If you choose heco when withdrawing fire coins, click "Huobi eco chain"; If you select bep-20 when withdrawing money, click "binance smart chain"; If okexchain is selected during okex coin withdrawal, click "okexchain".
After clicking, you can enter the wallet of the corresponding chain, see the token you transferred by mistake, and transfer and manage normally.
If you want to transfer the token back to eth wallet, there are three points to note:
Tokens on different chains cannot be directly transferred to each other, which means that tokens in heco, BSC and other wallets cannot be directly transferred to eth wallets.
If you want to transfer the token back to the ETH wallet, you need to first transfer the token back to the exchange, where it comes from and where it goes back ~ select the charging channel at the exchange and select the same channel as when withdrawing the token. If heco is selected when withdrawing the token, heco is also selected when charging.
The handling fee tokens to be paid for each chain transfer are different. For example, heco chain transfer requires the platform currency ht of fire currency to pay the handling fee.
Finally, the ETH wallet that withdraws money to imtoken is re launched in the exchange. This time, please be sure to select the right channel erc-20 / eth.
common problem
1. Why does imtoken not support direct inter transfer?
It's not that imtoken doesn't support it, but that the current blockchain technology doesn't support it.
Imtoken is a decentralized wallet, and the assets are kept by users themselves. The exchange is a centralized platform. No matter which chain you fill in the assets from, it is a part of the assets under its custody, which can be turned from left to right.
Therefore, if you want to transfer tokens from other chain wallets to eth wallets, you need to transfer them back to the exchange first.
2. Why is it wrong?
In fact, most of the design mechanisms and principles of the blockchain developed by the trading platform are the same as those of Ethereum, so each eth network address can find the corresponding "clone address" in BSC, heco and other networks. Although you fill in the ETH address of imtoken when you withdraw money in the exchange, in fact, the exchange transfers the money to the "clone address" of the platform chain.
Imtoken wallet can normally receive tokens on the trading platform chain, but it will not be directly displayed in eth wallet. It needs to switch the node to the corresponding wallet.
3. How to return to eth wallet after switching?
Click the chain name under the wallet and select "Ethereum mainnet"

No matter which token is transferred in Ethereum, ETH is required as the miner's fee. So how do we set our imtoken wallet miner fee? There are two ways:

1、 How to set the miner fee of Ethereum for imtoken wallet?
1. Basic method
In Ethereum, the higher the miner's fee you give, the faster the transaction will be packaged. Imtoken provides a slide rod function that can quickly adjust the miner's fee. By sliding the slide rod, you can quickly set the miner's fee. Click "miner's fee" on Ethereum transfer interface and adjust miner's fee by sliding slide rod.
2. Advanced methods
Click miner fee in Ethereum transfer interface
Click Advanced Mode and enter corresponding contents in gas price and gas
PS: gas fee = gas price * gas, users can log in https://ethgasstation.info/ Check the gas price and gas that are most suitable for transactions in the recent period, so as to quickly complete the transfer operation.
2、 How to set the miner fee of bitcoin in imtoken wallet?
When carrying out transfer operation in bitcoin network, bitcoin is required as miner's fee, but the miner's fee mechanism of bitcoin is different from that of Ethereum. Miner's fee of bitcoin = bit * sat (Cong) required for this transaction
In the bitcoin transfer interface, click "miner's fee" and enter your user-defined fee in the user-defined handling fee column. Generally, more than 20 can succeed, but it depends on the situation.

How does imtoken Wallet Buy and sell EOS memory and EOS bandwidth? Enter the home page of imtoken wallet assets, click the "drop-down" button at the top to enter the wallet selection interface, and click "..." on the right side of your EOS wallet Button.

Enter the EOS wallet "management" interface of imtoken wallet, click resource management to enter the "resource management" interface.
PS: at this time, you can see your currently available EOS assets and the consumption of your currently used resources, including RAM (memory), net and CPU (bandwidth).
How to purchase RAM (memory)
Click the "memory" list to enter the "memory" interface, click the "buy" button, enter the amount you want to buy, and you can see the amount of ram resources you can buy. Click next, enter the password and pay.
How to sell RAM (memory)
Click the "memory" list of imtoken wallet, enter the "memory" interface, click the "sell" button, and enter the number of ram bytes you want to sell. Note: here is not the number of EOS you want to sell, but the number of resources. However, by entering the resource quantity, you can see the equivalent EOS quantity at that time on the right.
How to buy ram for others
Click the "memory" list of imtoken wallet, enter the "memory" interface, click "receiving account", and enter the account name you want to help purchase resources.
How to get CPU and net (bandwidth)
In the resource management interface, click the "bandwidth" list to enter the "bandwidth" interface, click the "mortgage" button, enter the number of EOS, and you will see the CPU and net resources you can buy.
Of course, you can also dynamically allocate your CPU and net resources through the "slide bar".
Click next, enter the password and make payment.
How to redeem CPU and net resources
In the resource management interface, click the "bandwidth" list to enter the "bandwidth" interface, and click the "Redemption" button. It should be noted that redeemable resources = total amount - used resources - resources to be consumed in redemption operation - resources that cannot be redeemed pledged by others.
How to buy CPU and net (bandwidth) for others
In the resource management interface, click the "bandwidth" list to enter the "bandwidth" interface. Enter the amount, and you will see the CPU and net resources you can buy. Click "receiving account" and enter the account name you want to help buy resources.
Click Next and enter the password

Imtoken wallet flash is a kyber agreement. During the exchange process, the token will not leave your wallet. The exchange will complete the atomic exchange on the smart contract of the blockchain and does not trust the third party.

offer
The tokenlon backend server obtains the flash quotation of imtoken wallet in real time from the blockchain kybernetwork smart contract.
Authorization token.
In case of token exchange for eth, you need to authorize the smart contract (erc20approve operation), which only means that you have the right to authorize kybernetwork smart contract to help you complete atomic exchange with market competitors in the future. If you do not need to exchange, you can turn off authorization.
IEX (flash) and DEX are atomic currency exchange functions based on smart contracts, but the implementation technologies behind them are different. IEX is based on kyber and DEX is a 0x transaction protocol. Similarly, when we use IEX and DEX, we need authorization, so why authorization?
IEX
IEX flash cash function is based on kybernetwork protocol, so when we use kybernetwork protocol to exchange other tokens, we need to authorize our account to kybernetwork's smart contract. Then, kybernetwork's contract will automatically match the current most reasonable exchange rate transaction and complete the user's exchange operation.
DEX
For example, if I want to exchange the order with z1we 2000x on the blockchain, I need to use the authorization of z1we 2000x to exchange the order. For example, if I want to use the authorization of z1we 2000x on the blockchain, I need to use the authorization of z1we 2000x to exchange the order, Finally complete the exchange.
be careful:
1. When using IEX, you do not need to authorize the use of eth to exchange other tokens, but you need to authorize the use of other erc20 tokens to exchange.
2. At present, when DEX is used, weth can only be used to exchange other tokens, not eth. Please use the IEX flash cash function to exchange the weth you need first.
Transaction rules
After submitting the imtoken wallet flash order, it will be broadcast to the Ethereum blockchain network and wait for the miners to pack. However, due to the rapid change of market price, the transaction may not be completed. You will see the final status of the order in the exchange record, whether it is success, failure or overtime.

Since the launch of Ethereum 2.0 beacon chain on December 1, 2020, more than 120000 verifiers have participated in the pledge of Ethereum 2.0, and obtained about 7.8% annual income while maintaining the safe and stable operation of beacon chain.

If users want to participate in the pledge in the current phase (phase 0) of Ethereum 2.0, the common schemes in the market mainly include the following types:
Self built node: users run eth1 and eth2 clients and maintain nodes by themselves;
Full custody: transfer eth to a trusted custody service provider for centralized custody, allowing users to participate in pledge in a small amount (less than 32 ETH);
Escrow based pledge pool: provide pledge pool tokens based on the fully escrow scheme to solve the liquidity problem of eth long-term locking;
Unmanaged cloud service: users retain the control of eth assets and pledge proceeds, and jointly manage the authentication node with the service provider through two keys.
Self built node scheme
The "self built node" scheme requires at least 32 Eth and the technical ability, energy and experience of the operation and maintenance verification node. Users independently manage the pledged funds and obtain the pledge income through continuous operation and maintenance.
Its advantage is that users have complete control over self built nodes, and there is no centralized risk of centralized hosting. However, it has high requirements for capital and professionalism, and it is difficult for ordinary users to participate.
In February this year, the American stacking service provider stacked had two large-scale node slashed incidents in a row, and nearly 100 verifier nodes were punished. These events made the public realize the high requirements of self built nodes for technology.
The "self built node" scheme belongs to a relatively small number of geek schemes, but such schemes meet eth2's expectations for the decentralization of verifiers to the greatest extent.
The official guidelines for self built nodes can be found in:
https://launchpad.ethereum.org
Fully managed solution
As the name suggests, in the "fully managed" scheme, users only need to transfer the ETH participating in the pledge to the custodian, which will manage and operate the Ethereum 2.0 verifier node 100% for users, and draw profits from the pledge income.
Users who choose such schemes do not need to worry about the operation and maintenance of the verification node, and the hosting institution will handle all node affairs. However, during the pledge period, the user no longer has the control over the assets. Due to the centralized custody of assets, once they are attacked, the user's assets will face great risks. At the same time, the user cannot know whether the online rate of the verifier of the custody institution is stable, whether the income level is reasonable, whether there is punishment and other details. Even users do not know whether the assets under custody are used for pledge. Therefore, for the "full custody" scheme, the credit and brand of the custodian institution are very important.
The "full custody" scheme is mainly provided by institutions with asset custody services, such as binance, coinbase, Kraken and other exchanges, as well as eth2 pledge services provided by some custody / centralized wallets. One notable feature of this kind of service is that it supports small amount (less than 32 ETH) pledge, because the custodian institution can help small amount pledgers "scrape together" 32 eth to participate in eth2 pledge.
Pledge pool scheme based on trust
Compared with the fully escrow scheme, the escrow based "pledge pool" scheme not only supports small amount (less than 32 ETH) pledge, but also solves the liquidity problem caused by the long-term lock of the pledge. The solution is to issue the pledge pool token to the pledgor as the pledge certificate at the same time of pledge. This kind of voucher generally exists in the form of erc20 token on eth1 (i.e. the current Ethereum network). Because it represents the principal and income of users participating in the pledge, its value is similar to eth on eth1 and can be freely circulated and traded on the blockchain / trading market.
At present, the common eth2 pledge pool tokens are:
Beth - launched by eth2 pledge service provided by currency security exchange
Seth - launched by Lido network
Aeth - launched by ankr
Veth - launched by Bifrost
The advantage of the escrow based "pledge pool" scheme is that the user has simple operation and does not need to worry about the operation and maintenance of the verification node. The service provider will handle all node affairs. At the same time, the capital threshold is very low, allowing small amount (less than 32 ETH) to participate, and solving the liquidity problem of eth's long-term lock-in.
However, it must be pointed out that although some "pledge pool" schemes apply multi sign, smart contract and other technologies to try to manage assets in a decentralized way, they are still fully managed assets in essence. The asset security risks brought by asset custody have to be considered. At the same time, there are also assets, assets and Revenue transparency and centralization risk.
In addition, the pledge pool token, which is committed to solving the liquidity problem, also brings new problems and risks. For example, the working mechanism of pledge pool tokens is different, which leads to users' understanding of high cost and token discount; The emergence of pledge pool tokens not only further the composability of defi, but also increases the potential risk.
Unmanaged scheme
"Unmanaged" scheme is a scheme type that allows users to maintain self-sustaining assets while participating in eth2 pledge. Compared with the self built node scheme, the "unmanaged" scheme helps users solve the problems of operation and maintenance nodes by introducing a third-party node service provider, while the control and ownership of assets are still in the hands of users.
Each verification node in eth2 pledge service corresponds to two keys, one is the verifier key, which is used to verify the block, and the other is the withdrawal key, which is used to retrieve the pledge eth principal and income.
Different from the above schemes, the "unmanaged" scheme allows the separate custody of the verifier's key and the withdrawal key. The withdrawal key is managed by the user in the decentralized wallet, and the verifier key is imported into the node client by the third-party node service provider for node verification and maintenance. This is also the biggest advantage of the "unmanaged" scheme:
The control and ownership of assets are owned by the user, and the service provider cannot control the principal and income of the user
The pledged funds fully correspond to the verification nodes on the eth2 chain, the node status is transparent and visible, and the online rate and income level can be tracked in real time
At the same time, due to the user's own control of assets, the risk brought by the third-party service provider is limited, that is, the potential maximum loss comes from the offline penalty and slashed penalty that the service provider may suffer when maintaining the node. After eth2 and eth1 merge or support the transaction function, users can retrieve the pledged eth principal and income at any time.
Although the "unmanaged" scheme is not a completely decentralized pledge method, nor does it allow users to participate in a small amount, unlike the "pledge pool" scheme, the "unmanaged" scheme not only ensures the ownership and control of users' assets to the greatest extent, but also allows users not to worry about verifying the operation and maintenance services of nodes, and the operation level of nodes is clear and verifiable, It is suitable for large asset holders with high security requirements to participate in eth2 and obtain stable income.
At present, the common pledge service providers supporting "unmanaged" schemes are infstones and stacked Us et al.
summary
If you want to participate in eth2 pledge, you can make appropriate choices according to the following conditions:
If your assets are less than 32 eth, it is recommended to choose the "pledge pool" scheme. It is recommended to select a trusted pledge pool according to the service provider's brand, pledge pool token and eth discount;
If your assets exceed 32 Eth and you have excellent technical strength and node operation and maintenance experience, it is recommended to choose the "self built node" scheme;
If your assets exceed 32 eth, but you are unwilling to pay too much operation and maintenance energy, and have high requirements for asset security and node performance, it is recommended to choose the "unmanaged" scheme.
At present, Ethereum 2.0 is still in its early stage, and the growth potential of eth2 pledge market is huge. In the current phase 0 stage, various pledge schemes meet the demands of different customer groups. When choosing a pledge scheme, you need to choose a suitable pledge scheme according to the amount of pledged funds and the security of the scheme.

What if imtoken wallet transfer is not packaged? The purchase and sale pushed by imtoken wallet has not been packaged for a long time because the mining fee is set low. Sometimes it is because Ethereum Internet is very crowded and the number of orders to be packaged is too small. Many customers are unable to find business when the packaging request times out or the radio program is unsuccessful.

Imtoken wallet transfer is not packaged. There are two solutions:
1. Wait patiently for the purchase and sale of the mined ore;
2. Apply the "acceleration" function to increase the mining fee of the transaction, set the mining fee as the best value of imtoken, and then accelerate the packaging rate of the transaction, so that the transaction can be pushed out as soon as possible
When Ethereum is crowded and has not been packed for a long time, suggestions to customers:
1. Increase the mining fee gasplice, and propose 4gwei above
2. If TX cannot be found or the packing request times out, the mining fee can be further increased and try again. However, please check the certification results according to Etherscan first to prevent repeated transfer problems
3. You can also try to set the Web3 connection point as: https://mainnet.infura.io
Reference connection:
Immediate mining fee proposal: https://ethgasstation.info
Today's sequence to be packaged: https://etherscan.io/txspending 、
To sum up, the above is the solution to the unpacked transfer of imtoken. In fact, it's nothing, just increase the handling fee.

Everyone had a dream of being a mystery detective when they were young. I don't know whether you still keep this curiosity in your heart, or have been submerged by reality. It doesn't matter. Today imtoken will go to the blockchain world with you to find out. Let's start with the simplest transfer and break down the reasons for their failure one by one.

Before starting the formal transfer, please make sure you have upgraded to imtoken version 2.0. In fact, some transfer problems can be avoided through product upgrading. It's like the difference between an old car and a new one. Do you want to continue driving Tesla Model 1 or start the latest Tesla Model 3 immediately? Friends who have used version 2.0, please share your smooth experience unreservedly in the comment area!
Don't worry for users who are still using 1.0. We have specially prepared a 2.0 migration guide for you: https://imtoken.fans/t/topic/19696
When you see a transaction and the transfer failure is displayed on imtoken, it is usually caused by the following three reasons:
1. Out of gas I gas is insufficient
2. Bad instruction I error
3. Reverted I fallback
Moreover, the miner's fee paid by transfer will not be refunded to your wallet. Of course, the reason is not that imtoken "swallowed" the fee. Please read on for the specific reasons

Mnemonic is mnemonic in English. In most people's impression, mnemonic = private key, which is a tool to import the wallet. In fact, mnemonic ≥ private key. Then, where do mnemonics come from and what are they used for?

blob. png
Take a more life-oriented example. I believe everyone is familiar with opening a bank account and saving money. Generally speaking, the money we have in the bank will have many accounts, and each account may have different purposes. When handling these accounts, we only need an ID card. In case the bank card is accidentally lost, it can also be reissued through the ID card. So in real life, we know that ID card is extremely important!
In digital currency, we need the same truth. As we all know, in the blockchain world, the account can be unlocked as long as the private key is retained, but generally speaking, the private key is composed of a long string of 64 bits. If we want to create multiple accounts, we need to remember more than one private key, and the cost of recording and saving is very large; In the process of recording massive private keys, there may be many problems you can imagine or can't imagine. For example, the address does not match the private key, or the problem of carelessly writing the wrong letter when recording, and so on. Due to the characteristic of "only recognizing the private key but not the person" of digital currency, these small errors are likely to lead to the inability to retrieve the assets.
It is therefore recommended that:
1. Imtoken wallet mnemonic is the only voucher that can restore wallet digital assets! Please make sure to make a backup and keep it properly. For the safety of your property, please try to avoid saving mnemonic words by saving screenshots to mobile phone photo album. You can save your mnemonic backup to USB flash disk and encrypt it! If you save mnemonic words by handwriting, please be sure to carefully check whether your mnemonic words are copied correctly!
2. Be sure to verify whether the mnemonic words of the imtoken wallet backed up are correct for many times. Ensure that the mnemonic words backed up are accurate and check whether the mnemonic words are correct for many times. You can use other wallets that support mnemonic words to import the mnemonic words you backed up, check whether the mnemonic words backed up are correct, and compare them back and forth several times. Don't be afraid of trouble, Once you copy one or two wrong letters (pay attention to the case of letters, and remember to leave a space between each word when entering) it's useless to cry for your father and mother!
3. Use physical backup. After backup, be sure to keep it properly. If you are not afraid of hacker intrusion, you can also use any networked device to store it. The safest thing is your own brain (not necessarily, in case you forget!).

Imtoken wallet supports directly going to Etherscan to query the current transaction status. Click the red box to directly go to Etherscan to query or copy the URL to the browser to open and view the transaction display status.

There are several transaction statuses:
Type 1: let's take the transfer of kybernetwork as an example, success.
Type 2: out of gas (miner's fee shortage) you can see my previous article about miner's fee. I won't explain the concept in detail here. If there is the following display on Etherscan, it means "miner's fee shortage".
Type 3: bad instruction is a common type of error. However, although such transactions fail, miners' fees will still be deducted. And the transaction amount will be returned and the transaction will be cancelled.
Type 4: a reversed error occurs, which is an error encountered during the execution of the contract. However, although such a transaction fails, the miner's fee will still be deducted, and the transaction amount will be returned and the transaction will be cancelled.
Bad instruction and reverted errors appear. It is recommended that users directly ask for token items in the relevant token item party community

How to add usdt to imtoken?
Let's introduce the tutorial of adding usdt to imtoken wallet.
The download method is as follows:
The following is the download address of Xiaobian. Click direct download to install and use
Imtoken wallet latest official version type: bank financial size: 37.18mb language: Simplified Chinese time: 2021-05-13 view details
1. Installation and download:
Open official website address: https://token.im/ Just download it.
You can also search and download in the app store. Support apple (need overseas ID), Android system Support: eth, BTC, EOS and other mainstream currencies imtoken is one of the mainstream wallets in the currency circle at present. It is a convenient and easy-to-use mobile light wallet app! Is a Multi Chain Wallet, bid farewell to the complex backup management. The payment method is simple and easy to import and export; Multi signature security.
2. Set Wallet:
After the download and installation is completed, open the app to display the two options of creating identity and restoring identity. Restoring identity refers to importing the wallet you previously owned. This is a novice tutorial, so you can ignore it here. Click the create identity option. Imtoken service agreement will appear. Click in the lower left corner. I have carefully read and agreed to the following terms. Click continue to create the identity.
3. Fill in identity information:
According to the prompt, fill in your wallet name, wallet password and wallet password prompt question (optional). Click create to create a wallet. After creating the wallet, the backup wallet interface will pop up to prompt us to back up the wallet (we must back up the wallet)
The set password must be well saved! Because of the particularity of the wallet, in consideration of security, imtoken will not store the password and cannot be retrieved! Only you know this password. You must remember it well!
4. Backup Wallet:
Backup wallet (as shown in the figure) can be said to be the most important link in the security of using digital assets! Many Xiaobai who just came into contact are not used to backing up their wallets or private keys, resulting in the complete loss of assets. There are also many Xiaobai who have just come into contact with the blockchain and are worried about the security of assets and the theft of money by hackers. According to incomplete statistics, the most common case of loss of digital assets is not theft, but users do not have a good backup wallet, or forget the wallet mnemonic or private key!
Click the backup mnemonic and you will be prompted not to take screenshots (as shown in the figure). This is the most important link! Click "I see"
Then copy and save the 12 mnemonic words neatly and clearly on paper in order, and click "next" to verify the mnemonic words: click 12 mnemonic words in order to verify. Finally, click Finish to finish the operation of backing up mnemonics.
Warm tip: please keep the paper copy of mnemonic words properly, which is an important way to retrieve your wallet in the future. And only I know that if it is leaked, others can use our mnemonics to transfer our assets! Therefore, please be sure to keep it in a safe and reliable private place. Never expose to third parties. Once mnemonic words are leaked to others, it is equivalent to providing digital assets to others
5. Safety self test:
After you are familiar with the tutorial (as shown in the figure), click the system prompt to quickly start the backup immediately. Then click "safety self test" at the bottom of the right figure
Considering the safety of the wallet, the newcomer suggests to study it first and then start the evaluation. Some basic questions are very simple.
6. Use Wallet:
After all the above operations are set up, you will have your own imtoken wallet.
A string of codes below the avatar is your collection address. Just like a bank account, others can transfer money to your wallet. Just fill in this address. A QR code can be generated on the left, and others can scan the code directly to transfer money to your wallet.
7. How to transfer to usdt?
Click the plus sign at the red arrow in the picture to add a new asset, then pull down to find usdt, or search usdt directly. After finding it, click the button on the right side of the usdt and switch to the on state. Then we can go back to the wallet home page and find that the option of usdt appears in the wallet.
Note: imtoken supports bitcoin based usdt (omni usdt), Ethereum based usdt (erc20 usdt), and wave field based usdt (trc20 usdt), which cannot be transferred to each other.
You can confirm the type of usdt through the address:
The address of omni usdt starts with 1 or 3 and can be stored in BTC wallet in imtoken.
The address of erc20 usdt starts with 0x and can be stored in eth wallet in imtoken.
The address of trc20 usdt starts with T and can be stored in TRX wallet in imtoken
Comparison of three usdts
Erc20 usdt is used by the largest number of users, and the usdt of each platform is basically dominated by erc20 usdt.
Trc20 usdt has the second largest number of users, the fastest transfer speed and the lowest miner fee, but some exchanges do not support this type of usdt.
Omni usdt is the earliest usdt. At present, it is used by a small number of people, requires high miner fees, and the transfer speed is slow.
Is imtoken reliable?
There is no doubt about this, and it has never set a threshold for new users. You can use it as long as you have the idea to sort out your own virtual currency, or tap more currency information and resources. There are also many valuable free resources here, so that new users can grow up quickly. Imtoken is also loved by everyone because it is an old brand, has accumulated a certain reputation and made certain achievements. In this way, people can rest assured to give their assets to it.
Mtoken is very friendly to newcomers. Its operation is easy to use. Even without professional training, you can learn a lot through imtoken's official website. In the past, people were willing to put their money in the exchange in order to obtain greater returns. Now the risk of fund management in the exchange has increased, and the anti risk ability of many products is not satisfactory, so there are reliable products like imtoken. In addition to keeping users' assets, it also brings long-term and considerable benefits. Anyway, at present, it is so. Imtoken gains popularity because it knows where users' needs are. By browsing imtoken's official website, you will find that it is divided into many functional sections, such as wallet science popularization, other tools, help center, etc. These are the contents that users will use, and they are arranged neatly and easy to find.
Now, the number of visits to imtoken continues to increase. It can be seen that old users have always adhered to its position in the mobile wallet.

This domestic wallet has aroused great repercussions all over the world, which has opened a door for expanding the horizons of Chinese users. Of course, its stability affects users' confidence, its content needs to be continuously enriched and its influence needs to be further increased.

Token is a kind of wallet digital currency used to store, trade and manage Ethereum digital currency.

As Ethereum is the second highest market value digital currency by far, the audience of Ethereum wallet is also very wide. Let's talk about how to create and use Ethereum wallet imtoken.
Step 1: Download imtoken.
Step 2: create a wallet. Enter the wallet name and password to create your own wallet.
Step3: after creation, mnemonics, keystore and private key can be exported.
Due to the concealment of imtoken wallet and the protection of user identity, imtoken wallet cannot store and retrieve the password. Therefore, remember to back up and properly keep the account name and password, wallet mnemonics, keystore and private key.
After this step is completed, we can use imtoken to transfer transactions and query the balance.
How can imtoken exchange for Ethereum quickly
The main interface has four columns: asset, market, discovery and me. Assets are all digital assets owned by individuals in their wallets. Digital currencies can be stored and transferred in this interface. The market is information such as the fluctuation of currency value.
What needs to be reminded here is that imtoken is a wallet based on Ethereum protocol. It cannot store digital currencies other than Ethereum, whether bitcoin with the first market value or other unpopular digital currencies. Moreover, the storage capacity of imtoken is not large. Android users are only suitable for storing single digit Ethereum tokens, while IOS users are only suitable for storing two digit Ethereum tokens.
The most important meaning of Ethereum's contract is the change of Ethereum's smart market.
Therefore, imtoken is only applicable to personal small zero wallets. If other digital currencies are involved, it is recommended to use wallets with more complete functions and more diversified currencies, such as bipay, Youdun, etc. This kind of wallet is very common. What is universality? In short, it is usually appropriate. For example, some wallets are not open source, and some wallets only support a few mainstream currencies, which has certain restrictions in the actual use process. The private key of Youdun is self-contained, and the smart contract matches. In cross chain multi currency exchange, the exchange can be completed without trusting a third party, with high security and anonymous transactions, so as to better protect personal privacy. The underlying infrastructure is completely open source to meet the needs of users and developers. 5-minute easy access, unified management of Multi Chain and multi currency, erc20 token transfer to automatic display management, easy management, use a set of mnemonic words to manage Multi Chain Wallet, bid farewell to cumbersome backup management, wallet can be switched freely, and all digital currency accounts can be controlled in one stop. The supported currencies are rich, including mainstream digital currencies such as BTC, Eth and usdt, as well as all erc20tokens, the platform automatically selects the best exchange rate, multi chain, multi currency, one key exchange, one key exchange, no loss exchange, etc.

In the article "how ordinary currency holders participate in eth2 pledge", this paper introduces the differences in security and complexity of different eth2 pledge methods. In this article, we will learn how to evaluate security.

You need to send 32 corresponding eth vouchers to the smart chain.
At the same time, you need to create a beacon on the wallet chain. Similar to eth1 wallet, only the beacon Chain Wallet created by yourself, you really own eth.
Once the wallet on the beacon chain is created, you will get two sets of keys: verification key and withdrawal key.
The verification key is used to verify these data blocks. If someone steals your authentication key, they will copy your node, causing you to lose the mortgage eth.
After enabling this withdrawal key, it will be used to extract eth. Similar to the eth1 private key, extracting the key gives you ownership (gain or loss) of eth.
Therefore, the security of your pledged eth depends on who will keep and keep these keys.
Can I cancel the imtoken pledge
Since the smart contract has not received the pledge income, the method of * decentralized pool has not been. Once the problem is solved, rocketpool is expected to go online in 2021.
How to participate in eth2 pledge through imtoken.
This paper attempts to integrate all eth2 pledge services available for mobile terminals. You can choose fully hosted services, that is, node services and semi hosted services.
Click "2 pledge mining" displayed under the balance of eth wallet to enter the pledge service interface. You can also find 2 zones on the browse page.
From the quality area of eth2, you will see ankr, Lido, hashquark, take fish、StakedUs…Rocketpool。 Next, let's take a look at their differences and specific operations.
Semi hosted service: Lido, ankr.
Lido
Press the Lido icon, enter the ETH quantity you want to pledge, and then click "take", which is as simple as that.
Ankr
Click ankr's icon, click "launchapp", and then click "start".
Type the ETH quantity to be pledged (minimum 0.5eth), and then click "take". The collateral eth must be locked before eth 2 is officially launched before it can be retrieved, which may take several years.
What's the difference between ankr and Lido?
Ankr users pay commission and Lido users pay 10% of the pledge remuneration.
In order to ensure the security of the withdrawal key, ankr now takes part of its withdrawal key offline, so ankr's trusteeship is stronger than Lido.
Because ankr has multiple verification procedures, it adopts threshold signature. If one party does not know a complete key, the verifier can verify a beacon chain. The verifier key is stored on the stkr threshold server, which is shared by ankr and other companies. In this way, a single verifier cannot make mistakes in the verification process.
Lido ensures the security of withdrawal key through distributed managed withdrawal key. According to the threshold signature, the key is divided into 11 separate industry public figures.
Therefore, if you want to do bad things, you should collude with many parties to raise the threshold of doing evil.
Unlike ankr, Lido's verification is done by an operator. Whether you choose ankr, Lido or other quality assurance suppliers, you need to believe in your technical ability and moral quality.
Lido and rocketpool promised that once the eth1 address can be used as the withdrawal address, it will change to a fully autonomous mode, and now all these are being prepared.
It is worth noting that bloxshaking is similar to ankr, but requires downloading desktop applications.
Nodes as a service: take fish,StakedUs。
Node as a service is also called "pledge as a service" and "verifier as a service". Its operation mode is like running a network server on a host service such as AWS.
This service can perform the whole verification process for you. Compared with the hosting scheme, you have one advantage: you can completely control the withdrawal key.
But it also means stakedus and stake Fish will ask you to generate, extract and upload credentials, which is more convenient on the desktop (at present, we are studying the use of the mobile terminal).
If you want to try the operation process on your hand, you can click the icon "stakedus" or "take. Fish" on the "Browse" page in imtoken, and then follow the prompts step by step until you ask for the public key.
It is worth noting that although ankr mainly focuses on running semi managed mode, it now seems to provide a node as a service mode. Ankr's approach is similar to the above two methods, and it needs to pay $13.5 or $0.5 per month.
Total custody service
Hashquark, infstones and cream can all be found in the pledge zone of imtoken. They all provide complete hosting services. It is worth noting that since this model cannot control users' assets, users using fully managed services need to have sufficient understanding and trust in the corresponding operators.

In the currency circle, investors who have contact with digital currency wallets have heard of the professional digital currency wallet imtoken wallet, which supports multi chain and multi currency management and exchange. At present, they have completed the a-round investment of imtoken wallet, so there are still many investors who choose imtoken wallet to store digital currency. As we all know, not all digital currency wallets can store bitcoin, So everyone who chose the imtoken wallet wants to know whether the imtoken wallet can store bitcoin? The following is a small series of imtoken's official website. Let's give you a detailed introduction. Can imtoken wallet store bitcoin?
Can imtoken wallet store bitcoin? How much can I save?

An imtoken wallet can store bitcoin. Imtoken now supports four chains: BTC, ETH, EOS and cosmos, so you can see four wallets in imtoken.

BTC wallet can store two currencies BTC and omniusdt.
Eth wallet can store eth, erc20 standard tokens and erc721 standard tokens.
EOS wallet can store tokens on EOS and EOS chain.

Is imtoken wallet really suitable for saving money?
Mtoken was founded in March 2016. As of October 2018, imtoken has more than 7 million users in more than 200 countries and regions in the world. Of course, imtoken has a great foundation on the client, but as a decentralized digital wallet, is imtoken really completely decentralized? Can you really store digital currency with confidence?
As we all know, in a world of virtual currency, your assets are stored on the blockchain. What exactly exists in the blockchain? The real existence in the wallet is the key corresponding to your account. With this key, you can prove your identity in the virtual currency world and change the account status (transfer / transaction). In this case, virtualkeys is actually a tool for managing and storing keys. The key is a private key, while the wallet address is derived from the public key.
Imtoken is a decentralized digital currency wallet. It will not store any sensitive information from the server (how does this prove? No one knows). Keys and mnemonics only exist on the user's own mobile phone, and are not uploaded to imtoken's server. Moreover, cloud synchronization function such as icloud (we can rest assured) is a default setting, such as icloud, It only exists on the user's own mobile phone. In addition, the core operations of users can also be completed by themselves, such as wallet generation, import, key storage, mnemonic word backup, transfer, etc., without interaction with imtoken server.
Is there anything about bitcoin that can be stored in imtoken wallet? Finally, the editor of imtoken's official website suggests that investors who hold a lot of cash or who do not trade frequently for long-term investment need to choose a professional hardware cold storage. Naturally, you can also configure a cold wallet, but this requires some professional knowledge. For short-term investors, due to the need for frequent transactions, Therefore, you can choose the exchange wallet, which makes the transaction more convenient, and reduces the repeated recharge, withdrawal and mining costs.

Why export wallet.

How imtoken switches between BTC wallet and isolated witness address.

Imtoken's BTC wallet supports two forms of addresses: ordinary address and independent witness address (segwit).
When inputting BTC wallet, you can select the imported address format. After importing the wallet, you can also switch the wallet address according to the actual use needs.
Operation steps:
How does imtoken switch addresses?
1. Open imtoken software, enter the asset page, and click on Button to enter the wallet management interface.
2. Click "switch address type"
3. Select normal and enter the wallet password.
4. Convert the wallet address to a normal address starting from 1.
be careful:
1. When isolating the witness address transfer, the miner's fee is lower than the normal address transfer.
2. The assets at the common address and the isolated witness address are not interconnected with each other, and the transfer is sent to facilitate the transfer of assets.

Imtoken does not support etc. if you transfer the wrong eth wallet address to imtoken, you can transfer it out through the following two methods:

1. Use candybar to transfer etc. Candybar entry: browse - recommend - candybar etc entry.
2. Use other electronic wallets,
Can I put etc in the imtoken wallet
PS: IE browser is not recommended for Windows system; The keystore exported by imtoken needs to be stored as a file and then used as a keystore file.
Security: since the security of other wallets is unknown, the second method is not recommended.
This article mainly introduces how to enter the imtoken wallet transfer tutorial. First, enter the wallet asset interface, click the ETH button above to enter the imtoken wallet list page; Select the wallet you want to use. Here, take eth wallet as an example. On the "resources" page, click a token in the list to see its details. There are two buttons below - collect money and transfer money.
Tip: of course, you can also use the imtoken wallet to slide the asset items you want to transfer or collect from left to right, so as to quickly operate the collection and transfer operations.
Press the collection button to enter the imtoken wallet receiving page. On this page, the top character is the address of imtoken wallet, the middle is the QR code corresponding to the address, and the bottom is "replacement asset" and "specified amount".
For the collection without a limited amount, you can directly copy the imtoken wallet address string or QR code to the converter. This address string is different from QR code or mnemonic words, so you can send it to others without worrying about security.
In case of, a certain amount will be charged. You can press the "specified amount" key in the lower right corner, enter the amount in the pop-up amount box, and click OK.
Click the transfer button in the lower right corner of the imtoken wallet asset interface to enter the asset transfer interface. For example, ETH, enter the amount to be transferred, and fill in remarks if necessary. Input the wallet address of the other party to the imtoken wallet receiving address.

Recently, a friend asked about the use of IM wallet, especially the miner's fee, so the money market is ready to tell you how to set the miner's fee of IM wallet.

When transferring money over Ethernet, no matter which token is transferred, ETH is required as the miner's fee. There are two ways to im Wallet:
1、 Basic type:
In Ethernet, the higher the cost you give to miners, the faster the transaction packaging. Imtoken provides a slide bar function that can quickly adjust the miner's cost. The miner's cost can be quickly set through the slide bar. Click "miner cost" on the Ethernet transfer interface and slide the sliding rod to adjust the miner cost.

How can the usdt of imtoken wallet be transferred to the exchange
As long as there is an address, the storage address of some currencies of the exchange (such as xrpxlmbts) is the same. Just send the money in the wallet directly to the collection address. Please note that it should be noted that some currencies in the exchange may be divided into erc20 tokens or mapped tokens. The presidents of the two addresses are different. When transferring money, you should pay attention to that there is generally a fool proof mechanism to remind you to avoid transferring the wrong address type. If you are not sure before the transfer, you can ask the customer service first.
Currency withdrawal method: to participate in the ICO project, you must first mention the ETH purchased from huocoin exchange to your wallet, which involves currency withdrawal. Basically, all websites that support eth transactions support currency withdrawal. After the user starts the currency withdrawal demand, he will receive the currency withdrawal confirmation email. After manually clicking to confirm currency withdrawal, the assets will be published to the blockchain network.
It should be noted that since the software itself is a wallet and the wallet is a tool involving asset security, we must make a backup of the wallet memory word or private key before officially using the wallet. This process is not afraid of trouble and must be completed carefully once and for all.
The transaction of the software accesses the cloud coin network. Click the Find button at the bottom of the application, and you can see the logo of the cloud coin. Click this flag and the scan page will appear. At this time, you need to log in to the cloud coin account and enter the user setting page of the cloud coin network.

Well, isn't it simple? Bitcoin miners operate almost the same, and the only miner fee mechanism is also different. Bitcoin miner fee = bitsat required by the exchange
In the bitcoin transfer interface, click "miner fee" and enter the user-defined fee in the user-defined handling fee column. Generally more than 20 can succeed, but it depends on the situation.
Specify im wallet miner fee.
In short, the miner's fee is the handling fee paid to the miner. When you transfer money in the Ethernet blockchain, miners should package your transaction in the blockchain so that the transaction can be completed. In this process, they will consume the computing resources of the blockchain, so they must pay.
Gaslimit and gasprice multiplied by gaslimit.
The default value of gaslimit is different for different operations in different periods. You can set gaslimit by yourself during operation. It should be noted that the number of gas units required to complete a transaction depends on the complexity of the transaction. The more complex the transaction is, the more computing resources need to be consumed, so more gas needs to be consumed.
Gasprice refers to the number of Gwei, which will affect the speed at which your transaction is packaged and placed in the blockchain by miners. If gasprice is set higher, it will give miners more motivation to package your transactions; On the contrary, if gasprice is set low, it takes a long time. If you are not in a hurry to complete the transaction, you can choose a lower gasprice to save money. In each transaction, you can adjust gaslimit and gasprice as needed.

Imtoken is an app that generates Ethernet wallet addresses. It can generate many Ethernet wallet addresses.

Download imtokenapp from app treasure.
2. You can create multiple wallets by logging in to the app to create wallets! Be sure to remember the password. If you lose it, you can't find it!
Copy collection address note: collection address collection!
Why does imtoken have multiple addresses?
Imtoken is an Ethernet based wallet. When we open the imtoken wallet, we can see many tokens in one wallet, and then look at the addresses of these tokens. How to save different tokens at the same address? How do wallets distinguish between different tokens and issue tokens to others?
First of all, we should mention the two accounts of Ethernet, the external account and the contract account. The external account is used to store the token balance and the contract account is used to store the code. The contract account can only activate the code through the external account. Therefore, when you issue tokens to others, the amount of tokens in the corresponding external account will be deducted.
If your wallet address is a, for example, you get 10 OMG and 20 pay through crowdfunding, then the external account of OMG will be recorded.
A:10
Pay external account:
A:20
A this address is not only the Ethernet address, but also the bookkeeping address of the external account of each token application, so imtoken can store various tokens. If you send tokens to others, you will only use the smart contract in the contract account to deduct the tokens in the external account.
To sum up:
The number of tokens and Ethernet in the wallet is temporarily calculated through the address.

Huo Coin Wallet is a centralized wallet and imtoken is a decentralized wallet. If daily transactions are frequent, they will be stored in Huo coin Pro wallet, which is more convenient for transactions; If the transaction is not frequent or online transaction is not required, it will be stored in imtoken, which is safer and faster. Let's make a specific comparison.

Decentralization and mnemonics:
Mnemonic words are standard for decentralized wallets. All decentralized wallets have mnemonic words.
Imtoken is a decentralized wallet, that is to say, the imtoken team doesn't know your specific information. If you lose your mnemonic and make a wrong transfer, the imtoken team can't help you and can only bear the loss.
Huo coin Pro wallet is not a decentralized wallet, and there is no mnemonic word. If the password is lost or the transfer is wrong, you can contact the Huo coin pro team to help solve it; But it also bears the risk that the exchange is hacked.
Full currency:
Imtoken is an erc20 based wallet, which can only store currencies developed on erc20, while other non erc20 currencies (such as bitcoin) cannot be stored.
(erc20 is the underlying protocol of Ethereum's smart contract. It can be understood that it is similar to Android platform. People can develop apps based on Android platform and develop various tokens through erc20.)
Huo coin Pro wallet is an exchange wallet, so it can only store the currencies with transaction pairs opened, and the currencies that cannot be traded in Huo coin Pro cannot be stored.
Differentiated currency address:
All currencies that imtoken can store are based on erc20, so it can share an address called general address.

Wallet is based on blockchain. Only transfer and transfer functions. Imtoken website or application does not record the user's account password, private key and mnemonic. If the user forgets the password, private key and mnemonic (cloud coin forgets the password online, which can be found through customer service). Ether coin (ETH) and Wright coin, like the classic of ether coin, are also fake versions of bitcoin. However, compared with Wright's stupid Shanzhai method (only copying source code and replacing encryption algorithm), Ethereum's Shanzhai is slightly innovative.

The currency of the exchange wants to mention the wallet and keep it by yourself? Facing the exquisite wallet, how to choose? This article mainly explains the operation guide for the creation and extraction of eth wallet!

Important reminder wallet must keep private key to help memorize words and passwords.
There are many kinds of wallets. The most important distinguishing criterion is whether to master the private key of digital assets. Remember, only by mastering the private key can you really own digital assets.
Wallet:
Imtoken is a mobile wallet; App can directly add mainstream digital currencies based on eth main chain, including SNT, pay, DGD, 1st and other currencies. After clicking the Add button, the new version also has the function of searching and adding new currency, but it only supports digital currency based on eth main chain.
1) After downloading and installing, click app to open it, and then click [create wallet]
2) Fill in the wallet name, password and password prompt.
In this small make-up, the password setting is more important, because imtoken does not store the user password, so it is impossible to find the password. If you set the password cumbersome, it is recommended to set more password prompt information. Therefore, if you forget the password and see the prompt information, you may recall the setting password.
3) After the wallet is created, you need to focus on saving help words and keystore.
4) It is generally recommended that you save it by hand, because mnemonics are suitable for restoring your wallet.

There are many centralized wallets on the market now, attracting users under the banner of convenience, speed, and high income. It should be noted that although centralized wallets are convenient to use, they are very weak for users to control. It is equivalent to the user entrusting the digital assets to the centralized wallet team for safekeeping. This is a kind of complete trust, and there is a risk of various losses such as server hacking and team escaping. It's the same old saying: super high returns are often accompanied by super high risk. It is recommended that you choose carefully.
