Swap BNB from BNB Chain to ARB on Arbitrum One

Swap BNB from BNB Chain to ARB on Arbitrum One. You send native BNB on BNB Chain and you receive the ARB token on Arbitrum One.

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. ARB is 0x912CE59144191C1204E64559FE8253a0e49E6548. Match it on Arbiscan, chain id 42161, not Nova. ARB cannot pay gas. ETH has to be in the receiving wallet or the token cannot move. This is not WETH and not a dollar token.

Diagram for Swap BNB from BNB Chain to ARB on Arbitrum One
BNB leaves BNB Chain. ARB is what can arrive on Arbitrum One.

Native BNB buys the governance token

You sell BNB and you buy ARB. The ETH peg is not the input. A stablecoin peg is not the input. There is no approval on BNB, but the fee still requires a remainder. If you drain BNB, the send never starts and no ARB is created. The trade takes ARB price risk the whole time the route is open.

ARB on One still needs ETH beside it

0x912CE59144191C1204E64559FE8253a0e49E6548 is not the gas coin. Arbiscan lists ETH separately. A wallet that receives ARB with no ETH can see the token and still fail a transfer. Nova will not show this balance. The ARB ticker does not substitute for chain id 42161 gas.

ETH and dollar pages if ARB was the wrong ask

Native ETH can pay fees after it arrives, and that is a different page. Native USDC and USDT are different pages. WETH is different again. The bridge guide is the hop, not an ARB price. Stay on BNB Chain if you did not need this token.

Fee remainder, ARB floor, ETH already waiting

Keep BNB for chain id 56. Read the minimum ARB. Confirm ETH is already on Arbitrum One. A 3 second source block does not deliver any of those three. Sign only on BNB Chain. Look up 0x912CE59144191C1204E64559FE8253a0e49E6548 on Arbiscan after, on chain id 42161.

Frequently asked questions

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

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

Does this route pay ETH as well as ARB?

No. It pays the ARB token at 0x912CE59144191C1204E64559FE8253a0e49E6548 only. ETH is what you must already hold on Arbitrum One, chain id 42161, to move that token. The BNB you send is the marker 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE on BscScan. There is no ERC-20 approval on it. Nova is not the destination.

Can ARB pay the Arbitrum fee after it arrives?

No. Gas on Arbitrum One is ETH. ARB is a separate token, and Arbiscan shows it that way. If the wallet has ARB and no ETH, you still cannot send it. BNB left on BNB Chain does not cover the gap. Add ETH first. This page does not mint that ETH for you.

What if I wanted native ETH and opened the ARB page?

Leave it unsigned. This route pays ARB, not the gas coin. The native ETH page uses the gas-coin marker as the payout and a different quote. Signing here sells BNB into the governance token. If that is not what you meant to hold, it is the wrong tool.
