USDT TRC20 vs BEP20 vs ERC20 – Which Network to Use and What It Costs
Legal notice: since 1 September 2026, under Decree 284/2026/ND-CP, individuals in Vietnam who trade crypto-assets other than through a provider licensed by the Ministry of Finance can be fined 30–50 million dong. Binance, OKX and Bybit are not licensed in Vietnam. coinglee provides price information for reference only.
USDT isn’t on one blockchain. The same token exists on several networks: Tron (TRC20), BNB Smart Chain (BEP20), Ethereum (ERC20), plus others such as Solana, TON, Polygon and Arbitrum. When you move USDT out of an exchange, you have to pick one. Pick the wrong one and the money can be stuck or lost.
You don’t need a network at all for P2P. When you buy USDT with dong on Binance, OKX or Bybit P2P, it moves inside the exchange. Networks only matter when you send USDT out of the exchange or in from somewhere else. Today’s P2P prices are on the USDT rate board.
The main networks compared
| Network | Also called | Address looks like | Typical exchange withdrawal fee | Notes |
|---|---|---|---|---|
| Tron | TRC20 | starts with T, 34 characters | around 1 USDT | The most common for P2P traders and wallets in Vietnam |
| BNB Smart Chain | BEP20 | starts with 0x, 42 characters | well under 1 USDT | Cheap; same address format as Ethereum |
| Ethereum | ERC20 | starts with 0x, 42 characters | several USDT, rises when the network is busy | Most expensive; only use it if the receiver needs it |
| Solana | SPL | 32–44 letters and numbers, no 0x | well under 1 USDT | Fast and cheap |
| TON | – | starts with UQ or EQ | well under 1 USDT | Exchange deposits usually need a memo/comment |
Fees change often. The exact fee is always shown on the withdrawal screen before you confirm, so check it there.
How to choose
- Ask the receiver which network their address is on. This decides everything. A TRC20 address can only receive TRC20 USDT.
- If both sides support several networks, pick the cheapest one they share. For most people that’s TRC20, BEP20 or Solana.
- Avoid ERC20 for small amounts. A fee of several dollars eats a large share of a 50 USDT transfer.
- Sending between two accounts on the same exchange? Use the exchange’s internal transfer (by email, phone or user ID). It’s usually free and instant, with no network involved.
Step by step: withdrawing USDT safely
- Copy the address from the receiver’s app. Don’t type it by hand.
- In the exchange, choose Withdraw → USDT, paste the address and pick the same network the receiver gave you.
- If the receiver is an exchange and the network uses a memo, tag or comment (TON and some others), fill it in. Without it the exchange can’t tell whose deposit it is.
- Check the first and last 4 characters of the pasted address. Some malware swaps addresses in your clipboard.
- For a new address, send a small test amount first, then the rest.
- Save trusted addresses in the exchange’s address book and turn on the withdrawal whitelist if it’s offered.
Sent USDT on the wrong network?
What happens depends on where it went:
- Same address format (for example BEP20 sent to an ERC20 address you own): if it’s your own self-custody wallet, the money is usually there. Switch the wallet to the network you used and it appears.
- To an exchange deposit address on a network that exchange doesn’t support for that address: contact the receiving exchange’s support with the transaction ID (TxID). Some exchanges have a recovery process, often for a fee, but it isn’t guaranteed.
- Missing memo or tag: contact the receiving exchange with the TxID and proof that the account is yours. This is usually recoverable.
- Different address formats (for example a T… address on Ethereum): the withdrawal screen normally rejects this, so it rarely happens.
Write down the TxID of every withdrawal. Without it, support can’t trace anything.
Other things worth knowing
- USDT can be frozen. Tether can block addresses linked to fraud or sanctions. Don’t accept USDT from strangers or “cheap USDT” offers outside P2P. If the coins come from a scam, they can be frozen in your wallet.
- Self-custody wallets need gas. Sending TRC20 USDT from your own wallet needs some TRX for fees. BEP20 needs BNB, ERC20 needs ETH. Exchanges include the fee in the withdrawal, so you don’t need these there.
- Network ≠ token. Some scams send fake “USDT” tokens with the same name. Only trust balances shown in your exchange, or check the token’s contract in a block explorer.
In short
For most people in Vietnam: TRC20, BEP20 or Solana for everyday transfers, ERC20 only when required, always match the network on both sides and send a test amount first. Before you sell USDT for dong, check what it’s worth in the converter, and read how to sell USDT for VND safely.
