When making a USDT transfer, many users are presented with a choice of three different chain types that are available, at which point users may face the situation that they don't know which chain type to choose when depositing and withdrawing.

At Bequant Global we currently support USDT OMNI, USDT ERC20 and USDTRX. The differences between the different chain types are described in detail. Please refer to the table below.

USDT-Omni is the USDT issued by Tether based on the BTC network. The currency deposit address is the BTC address, with deposits and withdrawals taking place on the BTC network. The protocol used by USDT-Omni is the Omni layer protocol built on the BTC blockchain network.

USDT20-ERC20 is the USDT issued by Tether based on the ETH network. Its deposit address is the ETH address, with deposits and withdrawals taking place on the ETH network. The protocol of USDT-ERC20 is the ERC20 protocol.
​USDT-TRC20 is the USD-pegged stablecoin issued by Tether on the TRON network. The token will be able to complete issuance, holding and transfer via smart contract on TRON, with a completely free and transparent process, zero transfer fee, and instant delivery.

If you deposit USDT20 to your Bequant Global account, you will need to convert these funds to USDT first to start trading. These two stable coins have the same value, but markets are open for USDT only. You won't see any market for USDT20 open in our Instruments.

After you're done trading, you can convert your USDT back to USDT20 if you would like to withdraw your funds to your ERC-20 wallet.

Note: Since the USDT in the three networks are not interoperable, users should carefully check if the address is correct when depositing and withdrawing. In order to avoid unnecessary losses due to wrong address, special attention should be paid to the different address styles of the three types of chains. Each type of chain has its own advantages and disadvantages, users can choose according to their own assets. If you choose a wrong address, please contact Bequant Global Customer service immediately.
