Swap WETH from Polygon to ETH on Arbitrum One
Swap WETH from Polygon to ETH on Arbitrum One. Polygon WETH leaves Polygon. Native ETH is what can arrive on Arbitrum One. This is not an unwrap. Polygon has no native ETH, and Arbitrum ETH is not mainnet ETH.
You sell 0x7ceB23fD6bC0adD59E62ac25578270cFf1b9f619. You buy 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE, meaning ETH on chain id 42161. WETH there is 0x82aF49447D8a07e3bd95BD0d56f35241523fBab1 and is not the credit. Polygonscan shows the token debit. Arbiscan shows native ETH. Not Nova. How to bridge assets between chains is the distinction.

Frequently asked questions
What is the best way to swap WETH from Polygon to ETH on Arbitrum One?
You sell 0x7ceB23fD6bC0adD59E62ac25578270cFf1b9f619. You buy 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE, meaning ETH on chain id 42161.
Is this the same as wrapping on Arbitrum?
No. Wrapping on Arbitrum One moves between ETH and 0x82aF49447D8a07e3bd95BD0d56f35241523fBab1 and stays on chain id 42161. This route starts with Polygon WETH at 0x7ceB23fD6bC0adD59E62ac25578270cFf1b9f619 and can finish as native ETH. Polygonscan and Arbiscan are both required. ETH is not WETH. Nova is the wrong network.
Do I need ETH on Arbitrum before I start?
You need POL on Polygon to send. The ETH credit is what this route can create, so a prior Arbitrum balance is not required for the credit to exist. You do need chain id 42161, not Nova. Arbiscan shows a native credit, not a WETH token line.
What if I wanted the wrapper to stay wrapped?
Then this page is wrong. It pays native ETH via 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE. The wrapped contract is 0x82aF49447D8a07e3bd95BD0d56f35241523fBab1. Sign this one only if spendable gas on Arbitrum One is the point. Mainnet WETH is a different chain. Do not start there and expect this Arbitrum credit. Stay on Polygon for the sell.
