Swap POL from Polygon to ETH on Ethereum

Swap POL from Polygon to ETH on Ethereum. Native POL leaves Polygon. Native ETH is what can arrive on Ethereum. Both quotes use the gas label, and they are still two different coins.

0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE means POL on chain id 137 and ETH on chain id 1. There is no ERC-20 on either side of this pair. Polygonscan shows the POL debit. Etherscan shows the ETH credit. Blocks are about 2 seconds on Polygon and about 12 seconds on Ethereum. Neither is the bridge clock. Read how to bridge assets between chains before you treat the identical string as one asset.

Identical text, different coins

The gas label is a stand-in, not a shared contract. Spending it on Polygon reduces POL. Receiving it on Ethereum increases ETH. WETH at 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2 is not the credit. ETH is not WETH. If you needed the wrapper, switch quotes.

Keep a POL remainder

You are spending the fee coin. The last POL cannot pay chain id 137. Wrapped POL at 0x0d500B1d8E8eF31E21C99d1Db9A6444d3ADf1270 is the wrong balance. This route never approves that contract.

The ETH you receive can pay mainnet

That is the point of buying the native label on chain id 1. It is not a stablecoin. POL against ETH can move before you sign. Take the minimum or refresh the quote. No finish time is published here.

X-chain confusion is a different network

This hop is Polygon to Ethereum, not Avalanche. Etherscan is the destination explorer. If someone told you to watch Snowtrace, they described a different route. Stay with chain id 1 for the credit.

Frequently asked questions

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

0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE means POL on chain id 137 and ETH on chain id 1. There is no ERC-20 on either side of this pair.

Why do both addresses match?

Because 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE marks native gas on each EVM chain. On Polygon, chain id 137, it is POL. On Ethereum, chain id 1, it is ETH. You do not approve it. Polygonscan shows the debit and Etherscan shows the credit. They are not one balance. Do not approve that label.

Is this a way to turn POL into WETH?

No. WETH is 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2. This route pays native ETH. ETH is not WETH. If a contract call needs the wrapper, wrap after the ETH arrives, which spends a little of that ETH on gas. Etherscan should show a native balance first. ETH is not WETH at any point here.

What if I hold WMATIC instead of POL?

Then stop. The wrapped contract is 0x0d500B1d8E8eF31E21C99d1Db9A6444d3ADf1270. This page spends native POL only. You also need native POL for the fee, so a wallet of only the wrapper cannot complete chain id 137. Unwrap, then leave a remainder. The wrapper and the native coin are different lines.
