Swap ARB from Arbitrum One to BNB on BNB Chain

Swap ARB from Arbitrum One to BNB on BNB Chain. ARB leaves Arbitrum One and native BNB arrives on BNB Chain.

Spend the governance token 0x912CE59144191C1204E64559FE8253a0e49E6548. Check it on Arbiscan. Arbitrum One, chain id 42161, not Nova. ARB is not gas. Hold native ETH for the fee. Receive native BNB, sentinel 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE on chain id 56. BscScan shows a BNB balance, not a BEP-20 and not pegged ETH. Blocks are about 3 seconds. Do not treat that as the time the route owes you.

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

A governance sale that refills another gas tank

People use this pair when they need BNB and they are willing to sell ARB to get it. The output can pay fees on chain id 56. It is not 0x2170Ed0880ac9A755fd29B2688956BD959F933F8 and it is not a stablecoin. It also does not appear on Arbitrum One to pay the fee you are about to sign. That fee is ETH. If the ETH row is empty, buy or bridge a little ETH first, then come back.

The sentinel is BNB only on chain id 56

The same hex on Arbitrum One means ETH. Context is the chain id in the quote. You are not receiving ETH on BNB Chain. You are not receiving ARB. BscScan will not list a token supply at the sentinel. Watch the account's BNB figure. If a custodian asks for a BEP-20 contract address for the deposit, native BNB is the wrong asset to send them.

Price and voting weight both change

You give up ARB voting weight on the amount you sell, and you take BNB price risk on what you receive. The minimum is the bound. Refresh when it expires. BNB Chain is the network that can spend this gas coin. Eighteen decimals on both tokens do not imply a one-to-one trade.

Wrong job if ARB is the thing you need to keep

Do not open this page to move ARB. Do not open it for pegged ETH, BSC USDT, or pegged USDC. Do not open it if the balance you hold is WETH or native ETH. Do not open it on Nova. A same-chain swap of ARB for ETH on Arbitrum One would leave you on chain id 42161 with no BNB at all.

Frequently asked questions

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

Spend the governance token 0x912CE59144191C1204E64559FE8253a0e49E6548. Check it on Arbiscan. XAUConnect compares live routes and lets your own wallet sign.

Is native BNB a BEP-20 I must approve to receive?

No. BNB is the gas coin of chain id 56, marked 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE. You do not approve it to receive it. Any approval is for ARB at 0x912CE59144191C1204E64559FE8253a0e49E6548 on Arbitrum One, paid in ETH. BscScan shows BNB as a balance. Pegged ETH is a different contract and is not this output.

Does selling ARB for BNB keep governance rights?

Only on ARB you do not sell. This route does not escrow tokens for voting and does not mint ARB on BNB Chain. The credit is native BNB. If you need the governance token for a proposal, lower the amount. Chain id 42161, not Nova, is where the remaining ARB still sits.

Why is ETH required if the goal is BNB?

The signature happens on Arbitrum One, and that chain charges ETH. BNB arrives later, on chain id 56, and cannot pay the earlier fee. The sentinel on the source is ETH, not a coupon for free gas. About 3 seconds is a BNB Chain block interval, not a waiver of the source fee.
