BNB vs BEP-20 Tokens
BNB is the native coin of BNB Chain and pays its gas. USDT on BNB Chain is a BEP-20 token and needs BNB for every transfer. Swapping all your BNB leaves USDT you cannot move, so keep a small BNB balance.
Step by Step
- Connect a wallet on BNB Chain with BNB.
- From: BNB. To: USDT on BNB Chain, or on Tron, Solana or Ethereum.
- Paste the destination address if it is on another network.
- Confirm in your wallet.
Mistakes to Avoid
- Leaving no BNB for gas.
- Depositing BEP-20 USDT to an exchange address that expects ERC-20 or TRC-20.
- Old “BSC” bridges with wrapped USDT versions; prefer routes that deliver native USDT.
