Swap USDT from Polygon to USDC on Base
Swap USDT from Polygon to USDC on Base. Tether USDT leaves Polygon. Circle USDC is what can arrive on Base. The credit is native USDC, not the older bridged USDbC.
Spend 0xc2132D05D31c914a87C6611C10748AEb04B58e8F. Receive 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913. USDbC is 0xd9aAEc86B65D86f6A7B5B1b0c42FFA531710b6CA and is not this output. Polygonscan shows Tether. Basescan shows Circle on chain id 8453. How to bridge assets between chains is the habit of reading the contract, not the ticker.
USDbC is the miss
Tether does not survive
ETH later

Frequently asked questions
What is the best way to swap USDT from Polygon to USDC on Base?
Spend 0xc2132D05D31c914a87C6611C10748AEb04B58e8F. Receive 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913. XAUConnect compares live routes and lets your own wallet sign.
Is the arriving USDC bridged USDbC?
No. USDbC is 0xd9aAEc86B65D86f6A7B5B1b0c42FFA531710b6CA. This route buys native Circle USDC at 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base, chain id 8453. You sell Polygon Tether at 0xc2132D05D31c914a87C6611C10748AEb04B58e8F. Basescan is the check. The word USDC on a ticker is not the contract. USDbC is a separate Base address. Match the native contract.
Why do I still need ETH?
Because USDC is not gas on Base. ETH is, on an Ethereum layer 2. This route does not buy ETH. Keep some ETH on chain id 8453 if you need to move the USDC after Basescan shows it. POL was only the Polygon fee. There is no bridge finish time here.
Can the output stay Tether?
Not on this page. You are buying Circle. If a venue asked for Tether, switch routes before you approve 0xc2132D05D31c914a87C6611C10748AEb04B58e8F. Polygonscan should show that Polygon contract, not Ethereum USDT. Issuers are not interchangeable. Switch routes if the venue demanded Tether. Circle will not satisfy that form.
