Swap ARB from Arbitrum One to USDC on Ethereum

Swap ARB from Arbitrum One to USDC on Ethereum. ARB leaves Arbitrum One and Circle USDC arrives here on Ethereum.

ARB is the governance token at 0x912CE59144191C1204E64559FE8253a0e49E6548. It is not ETH and it does not pay gas. Confirm the contract on Arbiscan. The network is Arbitrum One, chain id 42161, not Nova. Fees are native ETH at the sentinel 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE. Circle USDC you can receive is 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Ethereum. Etherscan is the check. Chain id 1 blocks are about 12 seconds, which is not a credit schedule.

Diagram for Swap ARB from Arbitrum One to USDC on Ethereum — ARB leaves Arbitrum One. USDC is what can arrive on Ethereum.

You are selling the governance token

0x912CE59144191C1204E64559FE8253a0e49E6548 is ARB on Arbitrum One. Spending it means those units no longer vote from this wallet. The route does not escrow them for later voting, and it does not deliver ARB on Ethereum. The output is Circle USDC. If you still need ARB for a governance proposal, sell only the surplus. Eighteen decimals on ARB are not the six decimals you will see on the USDC side.

Gas is a second balance you must hold

A wallet full of ARB and empty of ETH cannot approve or swap. Native ETH on chain id 42161 pays the fee. The sentinel is not ARB. Bridged representations and the official ARB contract are easy to confuse if you only read the ticker. Arbiscan's page for 0x912CE59144191C1204E64559FE8253a0e49E6548 is the spend. Nova will not show this as the same chain even when the token name looks familiar.

Circle USDC is a price, not a peg to ARB

ARB floats. USDC targets a dollar. The minimum on the quote is the only floor you have, and it expires with the quote. Do not treat a round number of ARB as a round number of dollars. How cross-chain bridges work explains the wait between networks, but it will not freeze the ARB price while you read. Refresh if you leave the screen.

Wrong if you wanted ARB to arrive as ARB

This page is the wrong one when the goal is to hold ARB on Ethereum, or to hold ARB anywhere. It converts to Circle USDC at 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48. It is wrong for Tether, Maker DAI, WETH, and native ETH on mainnet. It is wrong if you meant a same-chain sale into USDC on Arbitrum One, where the Circle contract would be 0xaf88d065e77c8cC2239327C5EDb3A432268e5831 instead.

Frequently asked questions

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

ARB is the governance token at 0x912CE59144191C1204E64559FE8253a0e49E6548. It is not ETH and it does not pay gas.

Will I receive ARB on Ethereum from this page?

No. You spend ARB at 0x912CE59144191C1204E64559FE8253a0e49E6548 on Arbitrum One, and the asset that can arrive is Circle USDC at 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48. Confirm that USDC on Etherscan. If you need the governance token itself on another chain, this output is the wrong shape. You also give up the ARB you sell.

Does ARB pay the fee on Arbitrum One?

No. Gas is native ETH, sentinel 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE, on chain id 42161. ARB is an ERC-20 and may need an approval, which also costs ETH. Arbitrum Nova is not this network. If the ETH row is empty, the ARB balance cannot move, no matter how large it is.

Is this USDC the same contract I use on Arbitrum?

No. Arbitrum Circle USDC is 0xaf88d065e77c8cC2239327C5EDb3A432268e5831. This route can credit Ethereum Circle USDC at 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48. Both are Circle and both use six decimals, but they are different deployments. Check Etherscan for the receive address before you tell another app which USDC you hold. Confirm the address on the explorer before you sign.
