Swap POL from Polygon to WETH on Base
Swap POL from Polygon to WETH on Base. Native POL leaves Polygon. WETH is what can arrive on Base. The predeploy cannot pay gas, so this is a poor way to fund a new Base wallet.
Sell 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE. Buy 0x4200000000000000000000000000000000000006. Native ETH would use the gas label on chain id 8453, and this quote does not. Polygonscan shows POL. Basescan shows WETH. The same address on another chain is not your balance. Base still charges ETH after this wrapper arrives.
The Base predeploy cannot fund a new wallet
This Base quote ignores wrapped POL

Frequently asked questions
What is the best way to swap POL from Polygon to WETH on Base?
Sell 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE. Buy 0x4200000000000000000000000000000000000006. XAUConnect compares live routes and lets your own wallet sign.
Can I unwrap this WETH with no ETH?
No. Moving 0x4200000000000000000000000000000000000006 costs ETH on chain id 8453. This route does not deliver that ETH. ETH is not WETH. Basescan can list the predeploy while the ETH line is empty. If you needed gas, buy native ETH via 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE instead. The same address on another chain is not this wrapper.
Does Polygonscan approve the gas label?
It should not. 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE is native POL on chain id 137. You should see a native debit. If you are approving wrapped POL at 0x0d500B1d8E8eF31E21C99d1Db9A6444d3ADf1270, you are on the wrong token. Keep native POL for the fee. Basescan is where the WETH credit belongs. Chain id 8453 is the only match.
What if I wanted native USDC?
Leave this quote. Native USDC on Base is 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913. USDbC is 0xd9aAEc86B65D86f6A7B5B1b0c42FFA531710b6CA and is also not this output. WETH tracks ether, not a dollar. You would still need ETH later to move the USDC. Read the output before you spend POL. Dollars and this wrapper are different jobs.
