How to Swap on BNB Chain (BEP-20) — Step-by-Step
Trade BEP-20 tokens — BNB, USDT, WBNB and more — on BNB Chain at some of the lowest fees on the market. Covers wallet setup, gas in BNB, slippage and how to swap BNB assets off the chain cross-chain.
BNB Chain Basics in 30 Seconds
BNB Chain is an Ethereum Virtual Machine chain, so its tokens are BEP-20 — a format almost identical to ERC-20. Gas is paid in BNB, and fees are a fraction of Ethereum mainnet, which makes it a popular place to trade actively.
Step 1 — Fund Your Account With BNB
You need a little BNB for gas before anything moves — even when you are swapping TO BNB, the transaction that brings it in is paid in BNB on the way.
Send BNB from an exchange, or make your first swap a USDT-to-BNB route so both your balance and the gas reserve arrive together.
Step 2 — Connect a Wallet
MetaMask, Coinbase Wallet, Trust Wallet and 300+ others are supported. Add the BNB Chain network in your wallet, or let AEXI detect it. AEXI stays read-only until you sign a transaction.
Step 3 — Pick a Pair and Swap
Select the BEP-20 token you hold — say, WBNB or BUSD — and the token you want, like USDT or an altcoin. Enter the amount, review the quote and confirm. Most same-chain BNB Chain swaps settle in under 60 seconds.
Swapping BNB Assets Off the Chain
BNB Chain connects to Ethereum, Arbitrum, Base, Solana and more through AEXI: send BNB to ETH, USDT on BSC to USDT on Tron, or BEP-20 altcoins to another EVM network.
Each cross-chain route is atomic and includes destination gas, so funds arrive usable — no empty-wallet detour before the swap even matters.
