Swap USDC from Arbitrum One to ETH on Base
Swap USDC from Arbitrum One to ETH on Base. Circle USDC leaves Arbitrum One and native ETH arrives on Base.
Spend Circle USDC at 0xaf88d065e77c8cC2239327C5EDb3A432268e5831. Arbiscan, chain id 42161, not Nova. The fee there is already ETH, a different balance from the one you can receive. Receive native ETH on Base, sentinel 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE, chain id 8453. Basescan shows an account balance, not WETH. Base is an Ethereum L2. Its blocks are about 2 seconds. That is not a bridge schedule, and it is not Ethereum mainnet.
Two L2s, two ETH balances
Not mainnet, even though the ticker is ETH
Circle in, gas out
Wrong if you needed Base USDC or wrapped ether

What is the best way to swap USDC from Arbitrum One to ETH on Base?
Spend Circle USDC at 0xaf88d065e77c8cC2239327C5EDb3A432268e5831. Arbiscan, chain id 42161, not Nova. XAUConnect compares live routes and lets your own wallet sign.
Is ETH on Base the same balance as ETH on Arbitrum?
No. Both networks use ETH for gas, but chain id 42161 and chain id 8453 keep separate balances. You spend Circle USDC at 0xaf88d065e77c8cC2239327C5EDb3A432268e5831 and you still need Arbitrum ETH for the fee. The ETH you can receive is native gas on Base, sentinel 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE. Check Basescan, not Etherscan.
Is Base the same as Ethereum mainnet?
No. Base is an L2, chain id 8453. Ethereum is chain id 1. This credit will not appear as mainnet ETH. WETH on Base is 0x4200000000000000000000000000000000000006, and this route does not deliver that contract. About 2 seconds is a Base block interval, not a mainnet confirmation and not a bridge promise.
Will USDC.e pay for this quote?
No. The spend is native Circle USDC on Arbitrum One. The bridged USDC.e row is a different contract. If that is where the dollars sit, the quote will look short. Confirm the address on Arbiscan with the wallet on chain id 42161, not Nova, before you approve.
