Guide to USDT Transfer: Differences Between Three Chain Types Omni

Kahn332

USDT is currently the most widely used and highest market cap stablecoin. When withdrawing USDT, three types of chains will appear: Omni, ERC20, and TRC20. Many friends don't know which one to choose specifically, but in fact, all three types of chains can be used. Let's briefly explain the differences between them and how to choose.

What are the differences between the three chain types?
When withdrawing USDT, the three channels are respectively: Omni based on the Bitcoin network protocol, ERC20 based on the Ethereum network protocol, and TRC20 based on the Tron network protocol.

1. Omni-based USDT (issued based on the Omni protocol)

This type of USDT is stored in Bitcoin addresses, so each transfer (on-chain transfer) requires a small amount of Bitcoin as a miner fee. In addition to Bitcoin required as a miner fee for transfers, each initiation of a USDT transfer will correspondingly generate a very small Bitcoin transfer. Therefore, for each USDT transfer initiated based on Bitcoin, the wallet address must have at least 0.0002 Bitcoin to ensure the success of the transfer.

At the same time, when the recipient receives a USDT transfer, they will also receive a minimum amount of Bitcoin transfer.

2. Ethereum-based USDT (issued based on the ERC-20 protocol)

This type of USDT is stored in Ethereum addresses, and correspondingly, each transfer (on-chain transfer) requires consuming Gas, which is ETH. Currently, the vast majority of USDT in the market are based on Bitcoin, and the share of USDT based on Ethereum is very low (about 3%).

3. TRON-based USDT (TRON)

USDT based on the TRON network TRC20 protocol is stored in TRON addresses, and both recharge and withdrawal are carried out through the TRON network. Which transfer is the fastest? Because the TRON network has a TPS of up to 1500 TPS, currently, the fastest transfer is the TRON-based USDT.

Which USDT transfer is the safest?
Some people believe that the DPOS 27 super nodes of the TRON network are safer than the other two networks. The safest option is the Bitcoin network.

Which USDT to choose and has the lowest fees?

In summary, absolute security and speed of the blockchain cannot be achieved simultaneously for the time being.
For large transfers, it is recommended to use Omni-based USDT on the Bitcoin network, which has higher fees and is slower, but it is the safest.
For medium amounts, choose ERC20-based USDT, with moderate fees, moderate speed, and higher security.
For small amounts, you can use TRON-based USDT, which is slightly faster, and the TRON network transfer itself does not charge fees (although trading platforms may charge some fees).

Choosing one is indeed quite difficult.
