Swap USDT from BNB Chain to POL on Polygon

Swap USDT from BNB Chain to POL on Polygon. You send Binance-Peg USDT on BNB Chain and you receive native POL on Polygon.

The peg is 0x55d398326f99059fF775485246999027B3197955. Approve it on chain id 56. BscScan is the explorer. Gas is BNB, blocks about 3 seconds, 18 decimals. The payout marker 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE means POL on Polygon, the gas coin, not BNB and not WETH. Polygonscan shows that native credit. Chain id 137. Tether does not arrive. POL does, and it can pay later fees.

USDT leaves BNB Chain. POL is what can arrive on Polygon.

Leaving Tether for a moving gas coin

You sell 0x55d398326f99059fF775485246999027B3197955 and you take POL exposure. That is not a dollar-to-dollar hop. USDC and WETH are different pages. If a venue asked you to hold Tether on Polygon, this route is the wrong tool. Keep BNB beside the peg or the approval cannot pay for itself.

POL uses the gas-coin marker

Do not search 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE as an ERC-20 on Polygonscan. On chain id 137 it means native POL. The same string on BNB Chain would mean BNB, which is not the input here. The POL you receive can pay Polygon fees. It is still not WETH, and it is still not USDC.

Dollar pages if the peg was the point

Native USDC and Polygon USDT exist so you can arrive in Circle or Tether. This page sells that stability. It is also the wrong tool if you meant to spend BNB rather than the USDT peg. BNB Chain is the source. No POL price is guaranteed, and the source block time is not a finish time.

The POL you get can pay the next fee

You do not need old POL sitting in the wallet for this credit to be usable. You do need BNB on the source. Read the minimum POL against the Tether you give up. Sign on chain id 56. Switch the destination wallet to chain id 137 before you go looking for the balance on Polygonscan.

Frequently asked questions

What is the best way to swap USDT from BNB Chain to POL on Polygon?

The peg is 0x55d398326f99059fF775485246999027B3197955. Approve it on chain id 56. XAUConnect compares live routes and lets your own wallet sign.

Does this page pay Tether on Polygon or POL?

POL. The destination marker 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE means the gas coin on Polygon, which you check on Polygonscan. The token you send is Tether's peg, 0x55d398326f99059fF775485246999027B3197955, on BscScan. If you needed USDT after the hop, you are on the wrong page. Gas for the send is BNB.

Can the received POL pay fees without a separate top-up?

Yes, once it arrives. That is different from receiving USDC, USDT, or WETH, where you still need POL. You still need BNB on chain id 56 before the route starts. Polygonscan shows the native POL credit, not an ERC-20. This page does not promise the amount or the moment it shows up.

What if my BNB Chain wallet shows USDC, not this USDT?

The USDC peg will not be spent here. Its contract is 0x8AC76a51cc950d9822D68b83fE1Ad97B32Cd580d, and it has a separate route to POL. Approving the wrong peg does not start this swap. Confirm 0x55d398326f99059fF775485246999027B3197955 on BscScan. This peg's own page is the one that pays native POL.
