Swap USDC from Base to ARB on Arbitrum One

Swap USDC from Base to ARB on Arbitrum One. Circle USDC leaves Base, and the ARB token arrives on Arbitrum One.

Send Circle USDC from 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base, chain 8453. Check Basescan and approve if asked. The fee is ETH. Receive ARB at 0x912CE59144191C1204E64559FE8253a0e49E6548 on Arbitrum One, chain 42161. Check Arbiscan. ARB is the governance token. It is not ETH, it is not WETH, and it does not pay gas. Native ETH is 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE on each chain, and the two ETH balances are separate. This is not Arbitrum Nova.

USDC leaves Base. ARB is what can arrive on Arbitrum One.

Governance token, not a fee token

ARB is used for voting and for markets that list it. Validators on Arbitrum One are paid in ETH. A wallet that holds only ARB cannot move that ARB. If you came here to fund gas, you wanted native ETH, and this page sells you a volatile token instead. Price moves in ARB can dwarf the stable value you spent. Read the minimum.

Not Nova, and not USDC on One

Nova will not show this contract's balance. Native USDC on One is 0xaf88d065e77c8cC2239327C5EDb3A432268e5831. Bridged USDC.e is 0xFF970A61A04b1cA14834A43f5dE4533eBDDB5CC8. Tether is 0xFd086bC7CD5C481DCC9C85ebE478A1C0b69FCbb9. None of those is 0x912CE59144191C1204E64559FE8253a0e49E6548. If the order still says a dollar, leave.

ETH you must already have on One

The route does not attach ETH to the ARB credit. Move ARB later only if chain 42161 already has ETH. Base ETH paid the USDC side and stays on chain 8453. How to bridge assets between chains is the signing sequence, not a timer.

When the hop is unnecessary

If you can buy ARB with dollars already on Arbitrum One, you do not need to start from Base USDC. If your USDC buyer is on Base, stay there. Crossing only to swap and return pays twice. WBTC is unrelated, and it would not be native bitcoin even on a different route.

Frequently asked questions

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

Send Circle USDC from 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base, chain 8453. Check Basescan and approve if asked.

Does ARB pay gas on Arbitrum One?

No. ARB at 0x912CE59144191C1204E64559FE8253a0e49E6548 is the governance token, an ERC-20. Gas is ETH on chain 42161. The placeholder 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE means that ETH, not ARB. You need ETH on One before the new ARB balance can be transferred. Arbiscan can show ARB while the wallet still refuses to send it.

Is this Arbitrum Nova?

No. The destination is Arbitrum One, chain 42161. Nova is a different network. A Nova wallet will not display this ARB credit even after Arbiscan shows it. Switch to One, then look for 0x912CE59144191C1204E64559FE8253a0e49E6548. The source USDC remains on Base, chain 8453, until you sign.

I wanted to keep a dollar. Does ARB count?

No. You spend Circle USDC and you receive a governance token whose price moves. Native USDC on Arbitrum One and Tether are different routes. If the written instruction says USDC or USDT, do not sign this page. The minimum ARB on the quote is the number that matters, and there is no promised fill time.
