But at present, there are not many excellent usdt wallets on the market. This article will recommend several safe and reliable usdt wallets to help usdt users who need to use wallets as a reference.
Ledger Wallet
Ledger wallet, released in December 2014, is one of the world's most famous hardware cold wallets. Ledger well supports the usdt of Omni network. Since the security of cold wallets is much higher than that of hot wallets, ledger is very suitable for usdt holders who need large amount of storage.
Bitism
Bitpie is developed by Bitai team, which has more than 6 years of experience in wallet research and development. It is one of the earliest blockchain teams in the world. There has been no security accident in the past six years, and the wallet is extremely safe. Bitpie is the strongest usdt wallet in the world. It not only supports all four versions of usdt, but also supports one click trading of usdt. Different versions of usdt can be exchanged, free of miners' fees, and create massive usdt and other exclusive functions. Both novice and heavy users of usdt are very suitable for use.
Coinomi Wallet
Coinomi wallet, founded in 2014, is one of the earliest wallets supporting usdt. Currently, it supports two versions of usdt. As an old wallet, coinomi's security has been verified for many years. Compared with some new wallets whose technology has not been verified, users can rest assured.
Usdt popular science
Usdt is a digital currency issued by tether company, which anchors the US dollar. After several years of development, usdt has developed four different versions, and there may be more versions in the future.
Usdt Omni version, the earliest version of usdt. The omni version of usdt uses the omni protocol of bitcoin network for transfer. The address format is exactly the same as the bitcoin address. The address features start with 1 or 3. A typical omni usdt address is 1nb4qgpzxszhceykmaneb2qfejjsezxdtw. As the transfer speed is limited by the bitcoin network and the miner fee is high, the omni version of usdt is gradually replaced by other versions. However, the omni version of usdt is still the version with the largest circulation and the longest history.
Usdt-erc20 version, usdt using Ethereum network for transfer. The address starts with 0x. A typical address is 0xf9cf1d7bbb08ab5ed5810df96782f54a91364dec. As Ethereum's transfer speed and miner's fee are better than bitcoin network, erc20 version of usdt is currently the most frequently used usdt.
In addition to the main Omni and Ethereum versions, there are also the wave field version of usdt, which uses the wave field network for transfer. Address characteristics start with T. At present, the circulation is still relatively small, but some mainstream exchanges have begun to support it. The latest usdt has also been released on the EOS network. The address is characterized by a combination of 12 letters and numbers.
Due to different underlying networks, different versions of usdt in the wallet cannot be sent to each other.

Unlike all currencies, bitcoin does not rely on specific monetary institutions. It is based on specific algorithms. Through a large number of calculations, bitcoin economy uses many nodes composed of distributed databases to confirm and record all transaction behaviors in the whole P2P network, and uses password design to ensure the security of money circulation. The decentralized characteristics of P2P and the algorithm itself can ensure that bitcoin cannot manually control the monetary value through a large number of bitcoins. Cryptography based design can only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that its total number is very limited and very scarce.

The concept of cold wallet sounds high and simple.

In vernacular, in order to clarify several concepts:

The private key is a string of characters, which is your money.

Bitcoin address is the entrance to save money.

The essence of bitcoin wallet is a private key generator, which only has the transfer function of bitcoin.

As long as you have the private key in your hand, it doesn't matter what wallet you use. Because the private key is money, the wallet is just a tool.

So the key is to generate your private key, not what wallet to use.

When you generate bitcoin wallets, most of them are online.

The network means insecurity, which means that your private key is exposed on the network. How is there the risk of theft.

Cold storage is a way to ensure the security of encrypted currency by generating addresses offline, which means that it is almost impossible for private key hackers to crack.

Therefore, when using wallet software to generate private keys, two things should be paid attention to:

Ensure that the private key is generated offline and will never be exposed to the network.

Ensure that the software used to generate the private key is reliable and free of vulnerabilities.

How to accept bitcoin when the cold wallet is not connected to the Internet?



Here's the point. Let's move on to the theme:

1. If you have never connected to the Internet, it is perfect to prepare a computer.

(of course, there is no way to install the operating system without networking)

If you have special property to protect and pursue extreme security, it is recommended to use raspberry PI, which is a very cheap way. (you can reformat and restore every time you use the network.

2. Prepare a USB flash disk.

3. Recommend a website: https://www.bitadress.org/ , this is an open source website that can be safely used.

4. Right click to store the website in USB flash disk.

5. Open this web site on a computer that is not connected. Manually mouse to generate bitcoin private key and address.

6. Copy the private key and address to the USB flash drive and print it on paper.

7. Store the USB flash disk and paper in the safe, and it is better to back up more.

8. This bitcoin address can be used to receive coins safely Deposit money.

Note: bitcoin wallet is a random number generator. Most bitcoin wallets are randomly generated through software programs, while https://www.bitaddress.com The generation method of Org / basically realizes real randomness, because when you move the mouse, you may not know what kind of pattern you will draw.

This random way basically realizes that the private key is not brutally cracked

In the process of investing in BTC, we should be familiar with at least one BTC wallet, which is the most basic requirement. For friends who have just entered this industry, they usually put BTC in the exchange. In fact, these BTCs are stored in the bitcoin wallet of the exchange. The private key of the wallet is in the hands of the exchange and does not belong to our management. In theory, the exchange can escape and take the assets in your wallet.

In fact, only when the private key is in our own hands can we fully control the assets, which is also a feature of blockchain digital assets. In the world of digital assets, the private key is everything. Mastering the private key means owning digital assets. If the private key is lost, it means that the assets controlled by the private key are lost. For example, if the private key of bitcoin wallet is lost, this part of BTC will be lost forever.

In BTC digital wallets, wallets can be divided into cold wallets and hot wallets according to whether they touch the Internet or not. Cold wallet, i.e. offline wallet, i.e. the device on which the wallet is installed is offline. Because there is no Internet, the private key cannot spread on the Internet, so the cold wallet is much safer. For example, we can use offline mobile phones to create cold wallets, or use computers without Internet to create cold wallets. Strictly speaking, copying the private key on paper is also called a cold wallet.

Accordingly, a hot wallet is an online wallet. Since the device is online and the private key has the risk of online transmission, in theory, hot wallet is not as safe as cold wallet. The mobile wallet we usually use is basically a hot wallet (after all, this mobile phone).

Therefore, for the sake of security, we'd better put the BTC that we don't intend to trade recently in the cold wallet, which can ensure the security of assets to a great extent. Of course, whether it is a hot wallet or a cold wallet, the private key must be kept. For example, copy three copies, one for yourself, one for your parents, and the other in the safe.

How to create BTC cold wallet?

1. Create bitcoin cold wallet.

Take the BTC wallet of tokenpocket as an example to illustrate how to build a bitcoin cold wallet.

1. Find a mobile phone that is often not used. First download tokenpocket online (HTTPS: / www.tokenpocket. Pro /), and then turn off the network. For example, cut off WiFi or adjust the mobile phone to flight mode. Install the tokenpocket wallet on the mobile phone when offline.

2. After installing tokenpocket, select import wallet and bitcoin in the wallet system.

3. Select "cold wallet" in the import method.

4. In the cold wallet interface, enter mnemonic words, and then set the wallet password. After entering, click Start import below.

5. After successful import, create a cold wallet, as shown in the figure below.

Hot and cold wallets communicate through QR code scanning, and the private key does not touch the Internet, which can effectively prevent hackers from stealing.

2. Create a hot wallet.

After the cold wallet is completed, now create a hot wallet. The cold wallet needs to cooperate with the hot wallet to complete the final transfer.

1. Open the cold wallet in turn: "my - > Manage wallet", and then select the corresponding BTC wallet.

2. Open "advanced mode" in wallet details, and then click "configure observation wallet". Click to pop up the QR code.

3. Use another online TP wallet to scan the QR code generated in the above steps and import it into the wallet. Now, the creation of the observation wallet has been completed. Observing the wallet allows you to observe the assets of the wallet, but you do not have operation permission.

3. Use the cold wallet (with the hot wallet) to complete the transfer.

Hot wallet can be created with cold wallet and hot wallet after authorization. The specific steps are as follows.

1. Enter the transfer address, amount and other information in the wallet, then generate the data to be signed and display it in the wallet in the form of QR code, as shown in the following figure.

Note: do not close this interface, the last step needs to be used.

2. Then scan the QR code with the corresponding cold wallet. After scanning the signature, the cold wallet will get the QR code.

Please note that you need to use the scan code signature (not the camera in the upper right corner) to scan and observe the QR code in your wallet. After scanning, you will pop up the signature information, click "confirm" and enter the password in the pop-up box. Then generate QR code.

The display uses the corresponding observation wallet to scan the code to complete the operation.

3. Finally, scan the QR code generated in the cold wallet with the observation wallet to complete the transfer operation.

When scanning with the observation wallet, scan the QR code in the cold wallet with the camera mark under the QR code in the observation wallet (step 1).

BTC transfers through cold wallet and hot wallet.

It can be seen that in the whole process, the cold wallet is authorized through the scanning code, and the cold wallet and the hot wallet communicate through the scanning code. During the whole transfer process, the private key does not contact the network.

The above is the whole process of making BTC cold wallet and transfer using tokenpocket. The process of creating a cold wallet for other BTC wallets is similar to the transfer process. I hope it will help you.

What if the bitcoin private key is lost? One of the saddest things in the world is that you know you have a lot of bitcoin, but you forget what the private key is! Without the private key, you can't take out bitcoin and can only say goodbye to the wealth inside. Many people may not understand what is a private key? Why is it so important? Let the bee check Xiaobian and give a brief introduction. The private key is equivalent to the password of the account. Without a private key, there is no password. Naturally, you can't get bitcoin to protect the bitcoin stored in the private key.

What if the private key of bitcoin wallet is lost?



What about losing bitcoin private key? Can the private key be found if it is lost?

So, does losing the private key mean that there is no way to retrieve it? When we lose the private key, we can also try to find the private key in these three ways.

1. Use the backup keyfile or JSON file.

In the official wallet of Ethereum, there is a JSON document specially used to save the encrypted private key and public key. Sometimes you will get an alternate JSON file containing your private key from the browser. Pay attention to protect these files, hide or encrypt them, otherwise once the intruder obtains them, he can use your assets at will.

2. Mnemonics

Mnemonics consist of 12 random words, in other words, this is another form of private key. Your 64 private keys can be converted into several common words and words by algorithm, which can be obtained from a unified thesaurus. Different wallets will obtain words from different thesaurus.

3. Retrieve the wallet with digital wallet products.

At present, there are products in China that can help people who forget their private key to find wallets, such as P wallets. When a user loses his private key due to an accident, he can try to find his own digital currency with a low authority standby private key. The recovery instruction will not take effect immediately, but will work after a period of time. So some people are easy to be found by users.

What is the sub address of bitcoin? Bitcoin wallet is based on HD (hierarchical certainty) framework, which has a method to generate different addresses and manage addresses. Each public address of the user's wallet is generated from the xpub (extended public key) of the wallet. Anyone can easily track all payment records. This address generation method can greatly improve user privacy.

How to find the sub address of bitcoin wallet?

1. First click the imtoken asset page, switch to BTC wallet, and then click the QR code style button in the upper left corner to enter the collection interface.

2. At present, the main address of imtoken wallet bitcoin wallet is displayed. Clicking the sub address is the sub address of the current wallet.

This article mainly introduces how usdt transfers to others' accounts? The relevant information of TEDA currency / usdt transfer tutorial can be used as a reference for friends. Therefore, most digital currency exchanges regard TEDA currency as one of the legal digital currencies for legal currency transactions, which also makes many investors use TEDA currency for other digital currency transactions. For investors in the currency circle, TEDA currency is a very familiar digital currency, because TEDA currency is the token tetherusd based on the stable value currency US dollar launched by tether company. Therefore, most digital currency exchanges regard TEDA currency as one of the legal digital currencies for legal currency transactions, which also makes many investors use TEDA currency for other digital currency transactions. However, some investors do not know how to transfer to other accounts after the usdt transaction is successful. So how does usdt transfer to other accounts? The following monetary circle will describe in detail how usdt is transferred to other accounts?

How do I transfer usdt to someone else's account?

Now there are many transactions that can carry out usdt withdrawal. The small makeup in the currency circle will give you a brief introduction. First, select the currency, and investors can see the following options. No matter which currency chain type is selected, investors need to enter the currency address, so they want to transfer usdt to someone else's account and fill in the currency address directly, so the currency will enter the other party's account after success.

The normal arrival time of usdt transfer. Due to the bitcoin network, the arrival time of usdtomni is slightly slower, and it usually takes more than 30-60 minutes to display the arrival. If you don't arrive for a long time, it is mainly because the card is in the process. The small side of the following currency circle first tells you the usdt withdrawal and transfer process. When we initiate the usdt withdrawal process on the trading platform or trusteeship wallet, it is: transfer review = = send transaction broadcast = = entry review = = confirm entry.

ERC20. TRC20. What's the difference between omniusdt withdrawal?

1. Omni usdt has the best security, but the transfer speed is too slow. If you have a large order that is not in a hurry to trade, you can give priority to omni usdt.

In 2014, usdt was born in bitcoin network and officially launched several mainstream exchanges in February 2015. Before 2018, usdt has only one transfer path, that is, omni usdt based on bitcoin network. Omni usdt is stored on the bitcoin address, so bitcoin needs to be paid as the miner's fee for each transfer. Omni usdt in the bitcoin network chain, the cost of hacker attacks is very high, so the assets are relatively safe. However, its trading speed is very slow and can not meet the needs of today's encrypted trading market, but many large transactions still tend to omni usdt.

2. Erc20-usdt's safety and transfer speed are in the middle. It is suitable for frequent transactions in the digital money market. If you often do short-term transactions, erc20-usdt can be given priority.

In 2018, Ethereum network became popular and was launched in blockchain applications, and erc20-usdt appeared. Like omni usdt, erc20-usdt also needs to pay absenteeism fees, but the transfer speed is significantly improved. Due to its good security, erc20-usdt has been widely accepted in the market, and TEDA, the publisher of usdt, has also begun to support Ethereum erc20. Due to the high composite index, it is more popular on mainstream trading platforms.

3. Trc20-usdt transfer is the fastest. There is no handling charge for online transfer, but the security is relatively low. Suitable for friends who need to arrive quickly,

It is suggested to focus on small amount. Now, transfer generally takes only a few minutes.

In 2019, TEDA announced the issuance of usdt based on trc-20 agreement in the wave field, and trc20-usdt was born. It promises to be completely open and transparent at the time of issuance, with zero transfer fee and seconds. Different from the first two, trc20-usdt does not charge handling charges at present.

On April 9, sun Yuchen, CEO of bittent and Tron foundation, said that wave field Tron would launch a trc20 based stable currency usdt (usdt Tron) on April 9, and the new usdt would support Tron's decentralized application network.

Although the popular encryption network Tron is controversial, it is still a pioneer in the blockchain community. In order to take advantage of Tron's potential at the capital and application levels, it has reached a variety of partnerships in the industry. Now, tether, the founder of usdt, agreed to release a stable currency on the Tron platform.

The combination of wave field and usdt is the choice of their interests. The native usdt on the wave field chain can activate DEX, DAPP and Tron ecology to a great extent. Although the role of TRX has been weakened to some extent, usdt is easier to accept and bring traffic. Tether can use the DAPP ecology with rapid development of wave field to increase the direct participation ability of usdt in DAPP ecology, increase liquidity and help usdt compete for market share.

Where is the address of wave field usdt wallet?



In addition, sun Yuchen revealed that users of wave field version usdt will receive more than 100 million yuan of interest reward.

Sun Yuchen said in an interview that BoChang community needs a stable currency ecology, and tether also needs a more stable, reliable and advanced technology public chain. I think this is a win-win situation. In addition, the technology of usdt-tron is very mature, has reached the level of financial enterprises, safe and convenient, and can be used at any time.

At present, the omni public chain, a stable currency circulating in the market, first of all, the transfer cost is very high, and the peak transfer needs to pay 100 yuan. Sometimes the transaction fails due to the cost problem. The transfer of wave field public chain is completely fr

1、 Event summary.

Yesterday, with the exposure of microblog big v@ Xia Xueyi BTC, a new currency circle scam came into everyone's attention. For a time, everyone is in danger:

It may be: as long as you transfer usdt to the swindler through QR code, your account usdt will be transferred by the swindler. Why can a swindler control a user's wallet after a transfer?

The following is a brief analysis of criminal techniques.

2、 Process analysis.

Scan QR code:

Usdt fraud routine, tokenpocket wallet QR code theft, usdt security incident analysis.

Visit the following links:

After opening:

Usdt fraud routine, tokenpocket wallet QR code theft, usdt security incident analysis.

Scan the code with the tokenpocket wallet and try to transfer the money. Note that it must be the wave field chain. Note the upper left corner in the figure below:

Usdt fraud routine, tokenpocket wallet QR code theft, usdt security incident analysis.

During this process, you will find the following requests. Please note the method: approve!

Usdt fraud routine, tokenpocket wallet QR code theft, usdt security incident analysis.

Or use tronlonk to view:

Usdt fraud routine, tokenpocket wallet QR code theft, usdt security incident analysis.

The form of this contract is approve. The above figure refers to the request for approval of transfer of 90000 usdt!

The request signature here should be authorized, while tronscan recognizes the authorization as transfer.

Now you should understand that if you click to receive, approve authorizes you to authorize your usdt wallet to the attacker's address, and usdt within 90000 can be transferred by the attacker.

This method is also called approve fishing.

3、 Keep tracking.

The details of the signature request are as follows:

Usdt fraud routine, tokenpocket wallet QR code theft, usdt security incident analysis.

From the pop-up authorization, we can see the authorization of tvm7gsondpgup9sbtkwy2dhlvjhehgiy, and then check the transfer record of this address. We can see that all the transfer records of trc20 & trc721 show 90000:

Usdt fraud routine, tokenpocket wallet QR code theft, usdt security incident analysis.

These transfers are victims. This is actually a tronscan bug. 90000 is just authorization, not transfer.

For example, look at a transaction with a display amount of 90000:

to grant authorization:

Usdt fraud routine, tokenpocket wallet QR code theft, usdt security incident analysis.

It's just authorization. Xiaobai is prompted here. In fact, it's authorized to this address, which has nothing to do with the address displayed in the transfer interface.

Look at the victim's records:

Usdt fraud routine, tokenpocket wallet QR code theft, usdt security incident analysis.

Visible authorization 5 times, but not transferred out temporarily.

Several of them are like this and have not been transferred out. After unremitting search, we finally found a transfer out. It can be seen that the relatively large amount is 4276usdt:

Usdt fraud routine, tokenpocket wallet QR code theft, usdt security incident analysis.

It can also be seen from the above figure that tvm7gsondpgup9sbtkwy2dhlvhlvjhehgiy is the origination address, not the collection address, and the real collection address is taej7uzxallqjfx4bddnc1nishxrcfnqt.

Go to tronscan to check the income of this address, i.e. trc20 & trc721 transfer in record:

Usdt fraud routine, tokenpocket wallet QR code theft, usdt security incident analysis.

According to statistics, as of 12:50 pm on May 27, 2021, the first transaction occurred at 2021-05-2511:18:42 and the last transaction occurred at 2021-05-2709:52:45, with a cumulative amount of 120126.66usdt, about 780823.39 yuan.

In just two days, making money is faster than selling powder!

It can be seen that the attacker is a selective crime, and the amount of crime is generally more than 2000usdt. In other words, if you have too little usdt in your account, the attacker may despise it and get away with the transfer.

4、 Preventive measures.

When transferring money, be alert to approve fishing.

Or if it is impossible to prevent, try to transfer money through the address instead of scanning the QR code, because the QR code can carry too much information.

The tokenpocket wallet was stolen by the user. The above analysis missed the key step: how to sign and authorize the user. At present, the analysis only depends on starting the transfer, but how to sign? Is there a security error in the tokenpocket wallet itself?
