First of all, USDT, commonly known as TEDA currency, is a virtual currency that links cryptocurrency with legal tender dollar, and is a virtual currency that is deposited in foreign exchange reserve accounts and supported by legal tender. Users can use USDT to exchange US dollars for 1: 1 at any time (in short, it's a way for you to realize cash, and it's omitted here ... please make up for it yourself).
1. Omni-USDT based on bitcoin network, with BTC address as the charging address and BTC network as the charging and withdrawal method;
2.ERC 20- USDT based on Ethereum ERC20 protocol. The billing address is the ETH address, and the billing takes the ETH network;
3.TRC20-USDT is based on the wave field TRC20 protocol, and the coin-feeding address is TRON address, and coin-feeding and withdrawal take TRON network.
First of all, we should understand that there is no difference among the three USDT in exchange, but they are not interoperable in the chain. In other words, USDT and Ethereum based on Bitcoin are incompatible and cannot be transferred to each other. We can judge which USDT belongs to from the stored address. Therefore, when USDT exits the exchange, we must pay attention to the type of address.
All USDT addresses begin with 1
The address of TRC20-USDT starts with t.
The address of ERC20-USDT starts from 0x.
For large transfers, it is recommended to use USDT of Omini, a bitcoin network. The handling fee is expensive and slow, but it is the safest.
USDT of ERC20 is selected for medium transfer, with average handling fee, average speed and high security.
Small transfers can use Wave Field USDT, which is faster, and there is no handling fee for wave field network transfer itself (some trading platforms may charge some).
To sum up, the absolute security and speed of blockchain can't be both for the time being, but also depends on their respective needs! ! !
In addition, if the platform mistakenly calls the fee of USDT to the charging address of BTC, ETH and TRX.
You can only find the corresponding platform customer service, and some platforms can be retrieved.
There is also a case of charging by mistake. If it is recorded in the ETH or TRX address of a USDT trading platform that does not support ERC20TRC20, it may be necessary to wait for the corresponding kind of protocol USDT on the platform before extracting it.
