Swap POL from Polygon to WETH on Ethereum

Swap POL from Polygon to WETH on Ethereum. Native POL leaves Polygon. WETH is what can arrive on Ethereum. The wrapper you receive cannot pay gas, so this is a poor way to fund a new Ethereum wallet.

Sell the POL label 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE. Buy 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2. Native ETH would use that same gas label on chain id 1, and this quote refuses it. Polygonscan shows POL. Etherscan shows WETH. Ethereum is where you will need a separate ETH balance afterward.

WETH at the end strands a gas-poor wallet

If the job was to pay Ethereum fees, this route is wrong. 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2 does not pay them. Native ETH does. ETH is not WETH. Pick the native output when the next transaction has to be funded by what arrives.

POL is not the wrapped contract

0x0d500B1d8E8eF31E21C99d1Db9A6444d3ADf1270 is wrapped POL or legacy WMATIC. This quote spends native POL and still needs some of it left for chain id 137. Blocks there are about 2 seconds and are not the bridge finish.

Do not expect Ethereum WETH to be the thing you held

You did not hold 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2 before this trade unless you already used Ethereum. The credit is new. The debit is POL. Etherscan and Polygonscan will not show one transfer.

Volatile in, volatile wrapper out

POL and ether both move. The minimum on the quote is your floor. Refresh when it stales. A stablecoin output is the right page when you wanted dollars instead of WETH.

Frequently asked questions

What is the best way to swap POL from Polygon to WETH on Ethereum?

Sell the POL label 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE. Buy 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2. XAUConnect compares live routes and lets your own wallet sign.

Can I unwrap the received WETH with no ETH?

No. Unwrapping 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2 costs ETH on chain id 1. This route does not deliver that ETH. Etherscan can list WETH while the ETH line is empty. If you needed gas, buy native ETH via 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE instead. WETH cannot pay the unwrap if the ETH line is empty.

Does Polygonscan approve the gas label?

It should not. 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE is native POL on chain id 137, not a contract. You should see a native debit. If you are approving WMATIC at 0x0d500B1d8E8eF31E21C99d1Db9A6444d3ADf1270, you are on the wrong token for this page. Native POL and that wrapped contract are not interchangeable.

What if I wanted USDC rather than price exposure?

Leave this quote. Circle USDC on Ethereum is 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48. WETH tracks ether, not a dollar. You would still need ETH later to move the USDC. Read the output before you spend POL. Switch to a Circle USDC quote if you want dollars on Ethereum instead of WETH.
