Swap ARB from Arbitrum One to ETH on Ethereum

Swap ARB from Arbitrum One to ETH on Ethereum. ARB leaves Arbitrum One and native ETH arrives here on Ethereum.

The sold contract is 0x912CE59144191C1204E64559FE8253a0e49E6548 on Arbitrum One. Check ARB on Arbiscan. Chain id 42161, not Nova. ARB is not gas. You pay the fee with native ETH already on that chain. The receive marker is 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE, meaning native ETH on Ethereum, chain id 1, not WETH. Etherscan shows that as an account balance. Blocks are about 12 seconds. The bridge does not promise to finish inside one block.

ARB leaves Arbitrum One. ETH is what can arrive on Ethereum.

Two different ETH balances, plus ARB

You already need ETH on Arbitrum One to pay the fee. The ETH you can receive is a new balance on Ethereum. They do not net. Selling ARB does not refund the fee, and receiving mainnet ETH does not top up chain id 42161. If you spend your last Arbitrum ETH on the fee, that is expected. If you had no Arbitrum ETH to begin with, the ARB cannot move. The sentinel string looks the same in a quote. The chain id tells you which balance it names.

Native ETH is not the WETH contract

0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2 is WETH on Ethereum. This route does not credit it. If your next step is an ERC-20 pool, you will wrap after arrival and spend a little of the new ETH on gas. If your next step is simply paying a mainnet fee, native ETH is the useful shape and WETH would have been the awkward one. Know which of those you are before you sign.

ARB price is the moving piece

The amount of ETH is a market quote from a governance token into ether. It can change while the review sits open. Use the minimum. Request a fresh quote when the old one expires. Eighteen-decimal ARB versus eighteen-decimal ETH still does not mean one for one. Arbitrum One is only the network you leave. Ethereum is where the gas coin can show up.

Wrong if governance tokens must remain

Do not use this page to transport ARB. The output is ETH. Do not use it for Circle USDC, Tether, or DAI. Do not use it if you needed WETH specifically and cannot wrap. Do not use it on Nova. Do not use it if you meant to buy ETH inside Arbitrum One and never touch chain id 1. Those are all different receives.

Frequently asked questions

What is the best way to swap ARB from Arbitrum One to ETH on Ethereum?

The sold contract is 0x912CE59144191C1204E64559FE8253a0e49E6548 on Arbitrum One. Check ARB on Arbiscan.

Is the ETH I receive WETH in disguise?

No. The receive marker is 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE, native ETH on Ethereum. WETH is 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2. You sell ARB at 0x912CE59144191C1204E64559FE8253a0e49E6548. If a contract calls transfer on WETH, wrap first and leave gas. Etherscan will show the ETH as a balance change, not as that WETH token page.

I already have ETH on Arbitrum. Is that the destination?

No. ETH on chain id 42161 pays the fee and stays on Arbitrum One. ETH that this route can credit is on chain id 1. Same ticker, separate balances. Arbiscan and Etherscan are the two explorers to watch. Nova is a third network and is not either side of this quote.

Does selling ARB for ETH keep my voting rights?

Only on the ARB you do not sell. Spent units leave the wallet. They are not locked in a vote escrow by this page, and they do not reappear as ARB on Ethereum. The credit is native ETH. If you need the tokens for a proposal, lower the amount before you sign the quote.
