1. A little practical knowledge about USDT

Presumably every currency owner has tried to buy a lot of hot chicken, copycat, CX, and air on the exchange. coins.

In addition to some mainstream cryptocurrencies such as BTC, ETH, and EOS trading pairs, you will also see another stable currency, USDT.

From a legal currency perspective, USDT is a more convenient way for investors to deposit funds and exchange them for other cryptocurrencies. Because it is easier to see whether the market has fallen or risen.

So what is USDT?

USDT is Tether USD (hereinafter referred to as USDT), a token based on the stable value currency U.S. dollar (USD) launched by Tether. It is known as 1USDT=1 U.S. dollar, which is anchored to the U.S. dollar. It is convenient for users to exchange it 1:1 with legal currency at any time.

We don’t know if Tether strictly abides by the 1:1 reserve guarantee, and goes to the bank to deposit 1 US dollar after sending one. There are a lot of things going on at the moment. No matter whether it will be a thunderstorm or not, USDT is still one of the most mainstream stablecoins at present. It’s okay if you don’t accept it. You have to use it when it’s necessary. Just take it easy. Since something would happen sooner or later, we could only use it secretly at noon.

After talking for a long time, today I mainly talk about the types of USDT.

That’s right, USDT is no longer just running on a blockchain network today. If you are not careful, your USDT can easily be wasted.

USDT is currently running in three blockchain networks, including OMNI, ERC20, and TRC20. They correspond to the Bitcoin network, the Ethereum network, and the Tron network respectively.

In 2014, USDT was first issued on the Bitcoin blockchain based on the OMNI Layer protocol. Since then, it has gained the first-mover advantage and captured most of the cryptocurrency stablecoin market.

In 2018, USDT based on the ERC-20 protocol was officially issued on the Ethereum network.

In 2019, also in the TRON network, the TRON version of USDT, namely USDT-TRON20, was issued through the TRC20 protocol.

These three versions of stablecoins USDT-OMNI (USD), USDT-ERC20 (Ethereum), and USDT-TRC20 (Tron) use different protocols and belong to different blockchain networks. .

The most importantThe thing is, they are incompatible and cannot transfer money to each other.

Highlights:

Say important things three times.

So how to distinguish them as different networks? It's very simple, just look at the beginning of the address.

The USDT-OMNI (Bitcoin network) address starts with 1

The USDT-ERC20 (Ethereum) address starts with 0x

USDT -TRC20 (Tron) address starts with T

Remember, don’t make the wrong transfer again.

So in terms of pros and cons, since OMNI is based on the Bitcoin network, its security factor is relatively high and it supports more exchanges. Basically, the first USDT version launched by all exchanges will It is the OMNI version. If there is only one version, this is it.

In addition, another factor we consider is the speed of transfer. The speed of OMNI is very slow. The speed of the Ethereum version of USDT-ERC20 will be improved somewhat. How much is the mining fee? , depending on the degree of congestion. Personally, I feel that if the speed is not greatly improved and the transfer fee is not advantageous enough, not many people will use it, and this is still the case at present.

The TRON version of USDT-TRC20 claims to have zero transfer fees and is available in seconds. It seems that there are not many exchanges currently connected to it. If the experience is really improved, I believe some users will choose it.

Compared to USDT, a stablecoin that has a lot of bad history, a lot of mistakes, and thunderstorms sooner or later, I personally recommend that it be better to switch to other decentralized stablecoins such as Dai as soon as possible.

2. What is the usdtomni wallet address?

Just write your real address in the address. Blockchain information service provider registration self-examination chart. When selecting the subject as an institution, Only the unified social credit code can be filled in.
Extension: The issuance and transaction of USDT uses the Omni (formerly Mastercoin) protocol, which is a 2.0 currency based on the Bitcoin blockchain. USDT’s transaction confirmation and other parameters are consistent with Bitcoin. Users can wire USD to the bank account provided by Tether through SWIFT, or exchange for USDT through the exchange. When redeeming USD, just do the reverse operation. Users can also exchange Bitcoin for USDT on the exchange.

3. Can I check the usdt address?

It depends on the situation. The address itself is anonymous and cannot be found by ordinary people. Only the public security department can query the address information through technical means.

Blockchain address is generalRefers to the wallet address. The wallet on the blockchain is a tool for managing digital assets. The transfer of coins in and out and the records of transfers in and out are all achieved through the wallet. In a blockchain system, the private key is generally a 256-bit binary string randomly generated by a special random algorithm. The public key is generated from the private key through an irreversible algorithm, and the public key obtains the address through an irreversible algorithm (note : The address in some blockchain systems is the public key, and the address of the public key is calculated again to make the system more secure).

4. How to read the USDT wallet address

This address is the one you filled in at the beginning, so you can’t fill it in wrong at the beginning, otherwise it will not be transferred to what you want. in the address.

5. Blockchain USDT, those cold facts you don’t know

Recently, a fan sent a private message asking some questions about USDT #blockchain#. Today, hnsfans Let’s talk about some cool facts about USDT that you don’t know.

First of all, USDT, which we generally refer to as Tether, is a virtual currency that links cryptocurrency to the legal currency US dollar. It is a virtual currency that is stored in a foreign exchange reserve account and supported by legal currency. Users can use USDT for 1:1 exchange with US dollars at any time (simply put, it is a way for you to cash out, omit it here...please make up your own mind)

1. Based on Omni-USDT on the Bitcoin network, the deposit address is a BTC address, deposit and withdraw money through the BTC network;

2. ERC20-USDT based on the Ethereum ERC20 protocol, the deposit address is an ETH address, deposit and withdrawal The currency is on the ETH network;

3. Based on the TRC20-USDT TRC20 protocol, the deposit address is the TRON address, and the deposit and withdrawal are on the TRON network.

First of all, you need to understand one thing: there is no difference between the three types of USDT in the exchange, but they are not interoperable on the chain. That is to say, USDT based on Bitcoin and Ethereum-based are incompatible and cannot transfer funds to each other. You can determine which USDT belongs to from the stored address. Therefore, be sure to pay attention to the address type when depositing and withdrawing USDT on the exchange

The address of Omni-USDT starts with 1

The address of TRC20-USDT starts with T

< p> The address of ERC20-USDT starts with 0x

For large transfers, the USDT of Bitcoin network Omini is recommended. The handling fee is expensive and slow, but it is the safest

For medium-sized transfers, choose ERC20 USDT, which has average handling fees, average speed, and high security

For small-amount transfers, you can use TRON USDT, which is faster. The TRON network transfer itself does not Charge a handling fee (some trading platforms may charge some)

In summary, the absolute security and speed of the blockchain cannot be achieved at the same time, and it depends on each individual's needs! ! !

In addition, if the platform recharges USDT to the wrong recharge address of BTC, ETH, or TRX, you can only find the corresponding platform customer service, and some platforms can retrieve it.

There is also a case of incorrect deposit. If you deposit into the ETH or TRX address of a trading platform that does not support ERC20TRC20 USDT, you may need to wait for the platform to launch the corresponding type of protocol USDT before you can withdraw it.

6. Blockchain Cheese | What is the TRC20 wallet address

@blockchain Cheese will teach you a little bit about blockchain every day.

TRC20-USDT is USDT issued by Tether based on the TRON network. The deposit address is the TRON address, and deposits and withdrawals are made through the TRON network. TRC20-USDT (USDT-TRON) uses the TRC20 protocol.

TRC-USDT has the lowest asset security, but the fastest transfer speed, and there are no handling fees for on-chain transfers. Friends who are very concerned about transaction speed can consider TRC-USDT, but due to security considerations, it is best to focus on small amounts.

In April 2019, TEDA announced the issuance of USDT based on the TRC-20 protocol on Tron, and TRC20-USDT was born. When TRC20-USDT was issued, it promised to be completely open and transparent, with zero transfer fees and transfers in seconds.

Unlike the first two, there is currently no handling fee for TRC20-USDT transfers, which is also a highlight of TRON. However, the current development of TRC20-USDT is not very mature and security cannot be guaranteed.
