Swap BNB from BNB Chain to WETH on Ethereum

Swap BNB from BNB Chain to WETH on Ethereum. You send native BNB on BNB Chain and you receive WETH on Ethereum, not native ETH.

The BNB side is the marker 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE, the gas coin on chain id 56. No ERC-20 approval. BscScan shows the native send. Blocks are about 3 seconds. Leave BNB for the fee. WETH is 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2. Match it on Etherscan. Chain id 1. That wrapper cannot pay gas, so you need native ETH in the receiving wallet even after WETH arrives.

BNB in, wrapper out

You sell BNB, the gas coin, and you buy the WETH contract. The page does not sell Binance-Peg ETH. If the only ether-labelled asset you hold is that peg, this is the wrong input. There is no approval for BNB, but there is a fee in BNB. Draining the native balance to increase the trade size will stall the send.

You still need native ETH beside the WETH

0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2 arriving does not top up the gas balance. Unwrapping it later also costs ETH. If the destination is a fresh wallet, the WETH can be visible on Etherscan and still be stuck. This is the main way the route disappoints people who thought they bought spendable ether.

If you wanted the gas coin, switch pages

Native ETH is the payout that can pay fees by itself. USDC, USDT, and DAI are the payouts when you wanted dollars. This page is only the wrapper. Ethereum is where that wrapper lives. A same-chain trade out of BNB is enough when you never needed WETH on Ethereum. No amount is promised.

Spend BNB on gas before you spend it on size

Decide the fee remainder first, then the amount to swap. Read the minimum WETH, not just the estimate. BNB and ETH can both move, and WETH tracks ETH rather than BNB, so the quote is a moving target until you sign. A 3 second block is not a finish time. Ethereum blocks near 12 seconds are not one either. Sign on chain id 56.

Frequently asked questions

What is the best way to swap BNB from BNB Chain to WETH on Ethereum?

The BNB side is the marker 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE, the gas coin on chain id 56. No ERC-20 approval.

Is the WETH I receive able to pay Ethereum gas?

No. WETH at 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2 is an ERC-20. Gas is native ETH, which this page does not pay you. Etherscan lists them separately. The BNB you sent was the marker 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE on BscScan, and that BNB does not arrive as ETH. Bring ETH if you need to move the wrapper.

How is this different from swapping BNB to ETH?

The ETH route pays the native gas coin, which can pay fees after it arrives. This route pays the WETH contract, which cannot. If you do not have a specific need for the wrapper, the native page is the better fit and this one is the wrong tool. Both start with BNB on chain id 56.

What if the wallet on BNB Chain shows ETH but little BNB?

The ETH line is the peg token, and this page will not spend it. You need native BNB both as the asset to sell and as the fee. If BNB is only dust, the route cannot start. The peg has its own page to WETH. Check the native balance on BscScan before you blame the quote.
