Swap POL from Polygon to USDC on Base
Swap POL from Polygon to USDC on Base. Native POL leaves Polygon. Circle USDC is what can arrive on Base. You spend the gas coin, then hold a dollar token that cannot pay fees on chain id 8453.
The source is 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE, POL on chain id 137. The output is 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913, native USDC, not USDbC. Polygonscan shows a native debit. Basescan shows Circle. Leave POL for the fee. You still need ETH on Base later. Polygon is where that POL balance has to be.
Save POL before the Base USDC hop
USDbC is the wrong credit
ETH is still required later
POL has no allowance on the way to Base

Frequently asked questions
What is the best way to swap POL from Polygon to USDC on Base?
The source is 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE, POL on chain id 137. The output is 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913, native USDC, not USDbC.
Do I approve the POL label?
No. 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE is native POL on chain id 137. Polygonscan should show a native debit. The USDC you can receive is 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Basescan, chain id 8453. Approving the gas label is the wrong action. Keep some POL for the fee. USDbC is not this credit.
Is this USDC the bridged Base token?
No. USDbC is 0xd9aAEc86B65D86f6A7B5B1b0c42FFA531710b6CA. This credit is native Circle USDC. If a pool named the bridged contract, this route is wrong. Basescan shows which contract arrived. The ticker alone is not the check. Base is an Ethereum layer 2. USDbC is not the credit this quote pays.
Does the USDC arrive with ETH?
No. ETH is a separate coin on chain id 8453. This quote pays USDC only. Fund ETH yourself if you need to move the dollars. There is no finish time stated for the bridge. POL paid only the Polygon side. Etherscan will not show the credit.
