Recently, there were private messages from fans asking some questions about USDT # Blockchain #. Today, hnsfans will talk about some cold knowledge about USDT that you don't know.

first of all, USDT, commonly referred to as TEDA currency for short, is a kind of virtual currency that links cryptocurrency with legal tender dollar, and it is a kind of virtual currency kept in foreign exchange reserve account and supported by legal tender. Users can use USDT to make 1:1 exchange with USD at any time (simply speaking, it is a way for you to realize cash, which is omitted here ...... please replenish your brain by yourself)

1. Omni-USDT based on Bitcoin network, with the address of BTC as the charging address, takes the BTC network to charge money;

2. ERC2-USDT based on the Ethereum ERC2 protocol. The charging address is the ETH address, and the charging takes the ETH network;

3. TRC2-USDT based on wave-field TRC2 protocol, the coin charging address is TRON address, and the coin charging and withdrawal takes TRON network.

first of all, we should understand that there is no difference among the three types of USDT in the exchange, but they are not interoperable in the chain. That is to say, the USDT based on Bitcoin and Ethereum are incompatible and cannot be transferred to each other. We can judge which USDT belongs to from the stored address. Therefore, we must pay attention to the address type when the exchange withdraws the USDT.

The address of Omni-USDT starts with 1.

The address of TRC2-USDT starts with T.

The address of ERC2-USDT starts with x.

USDT of Omini, a bitcoin network, is recommended for large transfers, and the handling fee is expensive and slow, but the safest

USDT of ERC2 is selected for medium transfers, and the handling fee is average and the speed is average, and the security is high

Wave field USDT can be used for small transfers, which is faster, and there is no handling fee for wave field network transfers (some trading platforms may charge some fees)

In summary, blockchain. ! !

in addition, if the platform charges USDT to the charging address of BTC, ETH and TRX by mistake,

you can only find the corresponding platform customer service, and some platforms can be retrieved.

there is also a case of error charging. If it is charged into the ETH or TRX address of a trading platform of USDT that does not support ERC2TRC2, it may be necessary to wait for the corresponding kind of agreement USDT on the platform before extracting it.
