Swap ETH from Ethereum to USDC on Arbitrum One
Swap ETH from Ethereum to USDC on Arbitrum One. You spend native ETH on Ethereum and an Arbitrum One wallet receives Circle's native USDC.
Native ETH is marked 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE, the gas coin Etherscan shows on chain id 1. You do not approve it. The dollar that arrives is 0xaf88d065e77c8cC2239327C5EDb3A432268e5831 on Arbiscan, 6 decimals. Bridged USDC.e at 0xFF970A61A04b1cA14834A43f5dE4533eBDDB5CC8 is not the receipt. Leave ETH behind for the mainnet fee, because the coin you sell and the fee are the same balance. Blocks on Ethereum are about 12 seconds. The destination is Arbitrum One, chain id 42161, not Nova, and the USDC there still needs a separate ETH balance to move. Import the native USDC from Arbiscan once the wallet is on chain id 42161.

Frequently asked questions
What is the best way to swap ETH from Ethereum to USDC on Arbitrum One?
Native ETH is marked 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE, the gas coin Etherscan shows on chain id 1. You do not approve it.
Do I approve a contract for the ETH?
No. Native ETH uses 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE as a placeholder, not a token you import. You sign a send on chain id 1. Keep enough ETH unspent to cover gas, because the amount and the fee come from the same balance. Etherscan shows that native balance falling.
Which USDC row should increase?
The native one, 0xaf88d065e77c8cC2239327C5EDb3A432268e5831 on Arbiscan, 6 decimals, on Arbitrum One. USDC.e at 0xFF970A61A04b1cA14834A43f5dE4533eBDDB5CC8 stays put. If the app lists the bridged address, this route delivers the wrong contract. Chain id 42161 is the network to select, not Nova. Match the allowlist before you deposit.
When is an Ethereum swap enough?
When the dollars should remain on chain id 1 as Circle USDC at 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48. This bridge is the wrong tool for that balance. Open it only if the next use of the money is on Arbitrum One and the accepted contract is the native USDC.
