Swap WETH from Arbitrum One to POL on Polygon
Swap WETH from Arbitrum One to POL on Polygon. Arbitrum WETH leaves the wallet and native POL arrives on Polygon.
Sell 0x82aF49447D8a07e3bd95BD0d56f35241523fBab1, WETH on Arbitrum One. Arbiscan, chain id 42161, not Nova. Keep native ETH for the fee. Receive POL, sentinel 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE on Polygon, chain id 137. Polygonscan shows a balance, not the WETH contract 0x7ceB23fD6bC0adD59E62ac25578270cFf1b9f619. Blocks are about 2 seconds. That is not a fill time. Wallets may label POL as MATIC.
Wrapped ether becomes the other chain's gas

Frequently asked questions
What is the best way to swap WETH from Arbitrum One to POL on Polygon?
Sell 0x82aF49447D8a07e3bd95BD0d56f35241523fBab1, WETH on Arbitrum One. Arbiscan, chain id 42161, not Nova.
Is the output Polygon WETH or POL?
POL. The marker is 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE on chain id 137. Polygon WETH is 0x7ceB23fD6bC0adD59E62ac25578270cFf1b9f619 and is not the credit. You spend Arbitrum WETH at 0x82aF49447D8a07e3bd95BD0d56f35241523fBab1. Polygonscan shows POL as a balance. A MATIC label usually means that gas coin. Confirm that address on the explorer before you sign, and refresh the quote if it has expired.
Why is ETH required when I am selling WETH?
Arbitrum One charges native ETH for gas, chain id 42161. WETH cannot pay it. POL cannot pay it either, because POL arrives later on the other chain. Keep a fee balance. About 2 seconds is a Polygon block interval and does not remove the source fee. Nova is not the network that holds this WETH contract.
Does unwrapping WETH give me POL?
No. Withdraw on 0x82aF49447D8a07e3bd95BD0d56f35241523fBab1 returns ETH on Arbitrum One. This route is what can credit POL on chain id 137. If you unwrap first, switch to the native ETH route and still reserve gas. Do not expect the sentinel on Arbitrum to mean POL. Confirm the address on the explorer before you sign.
