Swap ETH from Arbitrum One to USDC on Avalanche C-Chain
Swap ETH from Arbitrum One to USDC on Avalanche C-Chain. Native ETH leaves Arbitrum One and Circle USDC arrives on C-Chain.
Spend native ETH, sentinel 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE, on Arbitrum One. Not WETH. Arbiscan, chain id 42161, not Nova. Reserve a fee. Receive Circle USDC at 0xB97EF9Ef8734C71904D8002F8b6Bc66Dd9c48a6E, six decimals, on the C-Chain. Snowtrace confirms it is not USDC.e. Chain id 43114, not X-Chain. Gas there is AVAX. Blocks about 2 seconds. That is not a promise.

Frequently asked questions
What is the best way to swap ETH from Arbitrum One to USDC on Avalanche C-Chain?
Spend native ETH, sentinel 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE, on Arbitrum One. Not WETH. XAUConnect compares live routes and lets your own wallet sign.
Which USDC address is native on the C-Chain?
0xB97EF9Ef8734C71904D8002F8b6Bc66Dd9c48a6E. That is Circle, six decimals, on chain id 43114. USDC.e is different. You spend native ETH, sentinel 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE, on Arbitrum One. Confirm Snowtrace. The X-Chain cannot hold this contract. Confirm that address on the explorer before you sign, and refresh the quote if it has expired.
Why reserve ETH if I am trying to leave Arbitrum?
Because chain id 42161 charges ETH, and you are selling that same balance. A zero remainder cannot sign. WETH is not a substitute. AVAX on the C-Chain cannot pay the source fee. About 2 seconds is a C-Chain block, unrelated to how much ETH you keep back. Nova is the wrong network.
Does Circle USDC pay for C-Chain transfers?
No. AVAX does. The sentinel on chain id 43114 is AVAX, and this route does not credit it. Hold AVAX before you try to move 0xB97EF9Ef8734C71904D8002F8b6Bc66Dd9c48a6E. The receive address must be a C-Chain account, not an X-Chain string. Confirm that address on the explorer before you sign, and refresh the quote if it has expired.
