Swap USDC from Polygon to ETH on Arbitrum One
Swap USDC from Polygon to ETH on Arbitrum One. Circle USDC leaves Polygon. Native ETH is what can arrive on Arbitrum One. That ETH is gas on chain id 42161, and it is not the ETH balance on Ethereum mainnet.
Spend 0x3c499c542cEF5E3811e1192ce70d8cC03d5c3359. Receive 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE, which on Arbitrum One means ETH, not WETH. WETH there is 0x82aF49447D8a07e3bd95BD0d56f35241523fBab1. Polygonscan shows USDC. Arbiscan shows ETH. This is not Nova. See how cross-chain bridges work before you treat every ETH balance as one wallet line.
Mainnet ETH stays on mainnet
WETH is the other output

Frequently asked questions
What is the best way to swap USDC from Polygon to ETH on Arbitrum One?
Spend 0x3c499c542cEF5E3811e1192ce70d8cC03d5c3359. Receive 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE, which on Arbitrum One means ETH, not WETH.
Is this Ethereum mainnet ETH?
No. The credit is native ETH on Arbitrum One, chain id 42161, marked 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE. Ethereum mainnet is chain id 1. Arbiscan shows the credit. Etherscan will not. You sold Circle USDC at 0x3c499c542cEF5E3811e1192ce70d8cC03d5c3359 on Polygon, not USDC.e. Arbitrum One ETH is not the balance on Ethereum.
Does the ETH arrive as WETH?
No. WETH on Arbitrum One is 0x82aF49447D8a07e3bd95BD0d56f35241523fBab1. ETH is not WETH. This route pays the native coin, which can pay gas. If you needed the wrapper, pick that output. Arbiscan should show ETH, not only a token line. The wrapper is a different contract and a different quote.
Can I start from USDC.e?
Not on this page. USDC.e is 0x2791Bca1f2de4661ED88A30C99A7a9449Aa84174. The quote names native Circle USDC. Polygonscan shows the approval. You also need POL on chain id 137. Nova and Ethereum mainnet are the wrong destination networks. Only native Circle USDC on Polygon can start this quote. USDC.e will not start it.
