Swap WETH from Polygon to USDC on Base
Swap WETH from Polygon to USDC on Base. Polygon WETH leaves Polygon. Native Circle USDC is what can arrive on Base. The credit is not bridged USDbC, and unwrapping on Polygon does not create it.

Basescan shows native USDC on chain id 8453, an Ethereum layer 2. POL pays the source. ETH pays later moves. Base is where that USDC can be checked.
USDbC is the wrong receive

Frequently asked questions
What is the best way to swap WETH from Polygon to USDC on Base?
Sell 0x7ceB23fD6bC0adD59E62ac25578270cFf1b9f619. Buy 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913. XAUConnect compares live routes and lets your own wallet sign.
Is the credit USDbC?
No. USDbC is 0xd9aAEc86B65D86f6A7B5B1b0c42FFA531710b6CA. This route buys native Circle USDC at 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base, chain id 8453. You sell Polygon WETH at 0x7ceB23fD6bC0adD59E62ac25578270cFf1b9f619. Basescan is the check. The ticker USDC is not the contract. Polygonscan shows only the debit. USDbC will not match this credit.
Does this USDC pay Base gas?
No. Gas on this Ethereum layer 2 is ETH, not USDC. This quote does not buy ETH. Keep ETH on chain id 8453 or the USDC waits. There is no finish time for the bridge. Polygon still charges POL to send the WETH. Basescan will not show a gas stipend.
What if I hold POL and think it is WETH?
POL is the native label 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE, not 0x7ceB23fD6bC0adD59E62ac25578270cFf1b9f619. This page cannot spend POL as the principal. Use a POL quote if that is the balance. Keep POL anyway, because chain id 137 takes it as the fee. POL is not the WETH you sell. Use a POL quote instead.
