Today I want to share something that many of you still find confusing when withdrawing funds—that is, choosing the right network for USDT. I’ve been confused about the network before, so I understand that feeling very well.

In reality, when withdrawing USDT from an exchange, you have quite a few network options, but the two most common are TRC20 and ERC20. The difference between them isn’t just on paper; it directly affects the fees you pay and the transfer speed.

What is the ERC20 network? Simply put, it’s a protocol for transferring USDT on the Ethereum blockchain. Ethereum is an established, very stable blockchain, supported by almost all exchanges and wallets. But the downside is that Ethereum’s gas fees are usually quite high, especially when the network is busy. I’ve had to pay up to a few dozen dollars just to transfer a small amount of USDT.

TRC20, on the other hand, is quite different. It runs on the TRON blockchain, which is designed to be fast and inexpensive. The transaction fees for TRC20 are almost negligible, and confirmation times are just a few seconds. However, not all platforms support TRC20, so you need to check beforehand.

Why is ERC20 so popular? Mainly because of its stability and broad support. If you’re unsure which network the other party supports, choosing ERC20 is usually safer. But if both sides support TRC20, I prefer to choose TRC20 because it’s faster and cheaper.

Choosing the network is actually very simple. First, ask the recipient which network they support. If they only support one of the two, you have no other choice. If they support both, then check the fees and speed on your exchange.

When withdrawing on an exchange, you’ll see a screen allowing you to select the network. It will display the transaction fee and estimated time for each network. Why is ERC20 so expensive? Because Ethereum is currently congested, gas fees have increased. TRC20, on the other hand, has very low fees, so if supported, I usually choose it.

A small tip: always double-check the recipient’s wallet address before sending. If you send USDT to an address that doesn’t support the network you chose, the funds could be lost. I know a few cases like that, which is very unfortunate.

In summary, if you need to transfer funds quickly and don’t want to spend too much on fees, choose TRC20 (if the other side supports it). If you’re unsure or the other side only supports ERC20, then ERC20 remains a safe choice. The most important thing is to ensure the network you select matches the recipient’s wallet or exchange to avoid unnecessary trouble.
