Swap ETH from Arbitrum One to WETH on Polygon
Swap ETH from Arbitrum One to WETH on Polygon. Native ETH leaves Arbitrum One and Polygon WETH arrives on Polygon.
Spend native ETH, sentinel 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE, on Arbitrum One, chain id 42161. Arbiscan, not Nova. Reserve the fee. Receive 0x7ceB23fD6bC0adD59E62ac25578270cFf1b9f619. Polygonscan should show WETH. The sentinel on Polygon would mean POL, not this token. Chain id 137. Gas is POL. Blocks about every 2 seconds. Unwrapping on Arbitrum would never create this address.
The sentinel is not the output on Polygon
A local wrap stays on Arbitrum
You still need POL to use the WETH
Wrong for dollar outputs and for gas outputs

Frequently asked questions
What is the best way to swap ETH from Arbitrum One to WETH on Polygon?
Spend native ETH, sentinel 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE, on Arbitrum One, chain id 42161. Arbiscan, not Nova.
Does Polygon credit native ETH for this route?
No. Chain id 137 has no native ETH gas. The output is WETH at 0x7ceB23fD6bC0adD59E62ac25578270cFf1b9f619. The sentinel 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE on Polygon means POL. You spend native ETH on Arbitrum One. Confirm WETH on Polygonscan. It cannot pay Polygon fees. Confirm that address on the explorer before you sign, and refresh the quote if it has expired.
Is this the same as wrapping on Arbitrum One?
No. A wrap there credits 0x82aF49447D8a07e3bd95BD0d56f35241523fBab1 and you stay on chain id 42161. This route can credit Polygon WETH instead. Reserve ETH for the source fee. About 2 seconds is a Polygon block, not the wrap function, and not a bridge promise. Nova is not either chain.
Why might the WETH amount differ from the ETH I sold?
Because this is a cross-chain quote, not a local deposit into a WETH contract. Fees and price impact sit in the minimum. Read it. If the quote expires, the ratio expires. Do not assume one native ETH becomes one Polygon WETH down to the wei. Etherscan's WETH is a different contract entirely.
