Swap BNB from BNB Chain to ETH on Arbitrum One

Swap BNB from BNB Chain to ETH on Arbitrum One. You send native BNB on BNB Chain and you receive native ETH on Arbitrum One, not on Nova.

Both sides use 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE. On BNB Chain, chain id 56, the marker is BNB. On Arbitrum One, chain id 42161, it is ETH. BscScan shows the BNB leaving. Arbiscan shows the ETH arriving. There is no ERC-20 approval on either gas coin. Blocks on BNB Chain are about 3 seconds. This is not WETH, not the ETH peg, and not the ARB token.

Same marker, BNB out and ETH in

The string is not one coin hopping chains. It means the gas coin of the chain you are on. You sell BNB and you buy ETH. Both can move. The Binance-Peg ETH contract is not an input. If that is all you hold, this page will not take it. Leave some BNB or the source fee fails.

The ETH you receive can pay Arbitrum fees

Because the payout is the gas coin, you do not need old ETH on Arbitrum One for the new balance to be usable. That is the difference from landing in USDC, USDT, WETH, or ARB. Arbiscan will not show an ERC-20 for this credit. Nova will not show it either.

WETH and ARB if you did not want the gas coin

Those payouts are other pages from the same BNB. This one is the wrong tool if a pool asked for the WETH contract or if you wanted the ARB token. How cross-chain bridges work is the wait, not a BNB to ETH rate. Nothing freezes the amount.

Read the ETH floor on two moving coins

The estimate and the minimum are different lines. Sign against the minimum. A 3 second block on chain id 56 does not freeze ETH. Confirm the wallet is on BNB Chain before the signature, then look on Arbiscan with chain id 42161. If the floor is too small, do not sign.

Frequently asked questions

What is the best way to swap BNB from BNB Chain to ETH on Arbitrum One?

Both sides use 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE. On BNB Chain, chain id 56, the marker is BNB.

Why are both addresses identical if BNB and ETH differ?

0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE stands in for the native gas coin. BscScan's native coin on chain id 56 is BNB. Arbiscan's native coin on chain id 42161 is ETH. There is no ERC-20 approval on either side. The ETH peg and the ARB token are separate assets and are not this route. Nova is not the destination.

Do I need ETH on Arbitrum before this swap?

No. The ETH from this route can pay fees after it arrives. You do need BNB left on chain id 56 to pay the source fee. If you spend the entire BNB balance, the send cannot be mined. Arbiscan is where the native credit belongs, on Arbitrum One, not Nova.

Can I undo it if ETH drops after BscScan confirms?

No. A confirmed BNB transfer is not reversed here, and the price is not insured. Read the minimum ETH first. The 3 second block is only BNB Chain. It is not a promise about how much ETH Arbiscan will show, or about when that credit appears.
