Recently, the data shows that the circulation of TRC20—USDT has exceeded 1 billion pieces. Some friends ask, what are the differences between TRC20 and ERC20 USDT? Today, the vernacular blockchain will briefly introduce to you that there are mainly 3 different types of USDT in the market.

Three different types of USDT

USDT is issued by the centralized company Tether. Before April 17 this year, there were 2 different types of USDT in the market.

The first is Bitcoin-based USDT (issued based on the Omni protocol). This kind of USDT is stored on the Bitcoin address, so every time you transfer (on-chain transfer), you need to pay a small amount of Bitcoin as a miner's fee.

In addition to the need for Bitcoin as a miner's fee for the transfer, every time a USDT transfer is initiated, a correspondingly small amount of Bitcoin transfer will be generated. Therefore, every time a Bitcoin-based USDT transfer is initiated, there must be at least 0.0002 Bitcoin in the wallet address to ensure the transfer is successful. At the same time, when the payee receives a USDT transfer, he will also receive a minimum amount of Bitcoin transfer.

The second is Ethereum-based USDT (issued based on the ERC-20 protocol). This kind of USDT is stored on the Ethereum address. Correspondingly, each transfer (transfer on the chain) needs to consume Gas, that is, ETH.

On April 17, the third USDT was born, which is based on the USDT issued by the TRON network (Tron). The TRC-20 USDT based on the TRON network is stored in the TRON address, and the recharge and withdrawal are all carried out through the TRON network, and the transfer is free.

Which of the above three USDT transfers is the fastest? Because the TRON network reaches 1500TPS, the transfer is currently the fastest.

Which USDT transfer is the safest? Some people say that TRON’s DPoS 27 supernodes are not as secure as the other two networks, and the most secure is only the Bitcoin network.

Which USDT to choose? Bitcoin-based USDT is recommended for large transfers, Ethereum-based ERC-20 USDT is a compromise, and Tron-based USDT can be used for small transfers, which is faster.
