Swap USDT from Polygon to USDC on BNB Chain
Swap USDT from Polygon to USDC on BNB Chain. Tether USDT leaves Polygon. Circle USDC is what can arrive on BNB Chain. You change issuer, and you also change decimals from 6 to 18.
Spend 0xc2132D05D31c914a87C6611C10748AEb04B58e8F. Receive 0x8AC76a51cc950d9822D68b83fE1Ad97B32Cd580d, Circle USDC on chain id 56. That is not Tether's 18 decimal token at 0x55d398326f99059fF775485246999027B3197955. Polygonscan, then BscScan. POL pays the source. BNB is required later if you move the USDC.

Staying in Tether is a different contract
The raw integer jumps
USDC still needs BNB

Frequently asked questions
What is the best way to swap USDT from Polygon to USDC on BNB Chain?
Spend 0xc2132D05D31c914a87C6611C10748AEb04B58e8F. Receive 0x8AC76a51cc950d9822D68b83fE1Ad97B32Cd580d, Circle USDC on chain id 56. XAUConnect compares live routes and lets your own wallet sign.
Is BNB Chain USDC 6 decimals like Polygon USDT?
No. 0x8AC76a51cc950d9822D68b83fE1Ad97B32Cd580d uses 18 decimals. Polygon Tether at 0xc2132D05D31c914a87C6611C10748AEb04B58e8F uses 6. Compare the amount on the quote. BscScan shows the Circle contract. Polygonscan shows the Tether debit. The integers will not match. A larger raw integer is only the decimals gap, not a larger payment.
What if I needed USDT on BNB Chain?
Then this route is wrong. Tether there is 0x55d398326f99059fF775485246999027B3197955. You would be buying Circle at 0x8AC76a51cc950d9822D68b83fE1Ad97B32Cd580d. Issuers are not interchangeable on a deposit form. Switch the output before you approve anything on Polygon. Tether on BNB Chain is a separate route with its own 18 decimal contract.
Does the USDC pay the next BNB Chain fee?
No. You need native BNB, the gas label 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE on chain id 56. This quote does not buy it. About 3 second blocks are the chain, not the bridge. Keep BNB in the receiving wallet if you must move the USDC. USDC is not a substitute for that gas coin.
