Swap USDT from Polygon to BNB on BNB Chain

Swap USDT from Polygon to BNB on BNB Chain. Tether USDT leaves Polygon. Native BNB is what can arrive on BNB Chain. A 6 decimal stablecoin becomes the gas coin on chain id 56.

You sell 0xc2132D05D31c914a87C6611C10748AEb04B58e8F. You buy 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE, which means BNB on this destination, not WBNB. Polygonscan shows the Tether debit. BscScan shows native BNB. There is no approval of the gas label. How cross-chain bridges work covers why that label changes meaning with the chain.

WBNB is the wrong finish

0xbb4CdB9CBd36B01bD1cBaEBF2De08d9173bc095c is the wrapped contract. This page pays native BNB, which can pay fees. If a router demanded WBNB, wrap afterward or change the quote. Signing here and expecting the wrapper is the wrong route.

You leave Tether on purpose

Keeping dollars on BNB Chain would mean USDT at 0x55d398326f99059fF775485246999027B3197955 or Circle USDC at 0x8AC76a51cc950d9822D68b83fE1Ad97B32Cd580d. Both are 18 decimals. This route buys BNB instead. Price can move.

POL must survive the send

The source fee is POL on chain id 137. Tether cannot pay it. About 2 second Polygon blocks are not the bridge clock. Leave POL even though the thing you want on the other side is a gas coin.

No bytecode behind the receive address

Do not hunt for a BNB token contract equal to the gas label. BscScan shows a native credit. An approval popup for 0xEeee means you left this route.

Frequently asked questions

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

You sell 0xc2132D05D31c914a87C6611C10748AEb04B58e8F. You buy 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE, which means BNB on this destination, not WBNB.

Is the arriving BNB an ERC-20 I must approve?

No. 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE is native BNB on chain id 56. There is no approval. BscScan shows a native credit. WBNB at 0xbb4CdB9CBd36B01bD1cBaEBF2De08d9173bc095c is a different asset. The token you sold is Polygon Tether, visible on Polygonscan. Do not approve the gas label. WBNB is a later wrap if a pool demands it.

Will my Tether balance on BNB Chain increase?

No. This quote does not buy 0x55d398326f99059fF775485246999027B3197955. It buys BNB. If you needed Tether, you are on the wrong page. Circle USDC at 0x8AC76a51cc950d9822D68b83fE1Ad97B32Cd580d is also a different output. Read the quote before you sign. Dollar outputs are different pages, and each names a different contract.

What if the minimum in BNB looks thin?

Do not sign a floor you will not accept. USDT against BNB can move while the quote sits open. Request a new one. About 3 second blocks on BscScan describe the destination chain, not when the bridge leg finishes. Refresh the quote and read the new floor before you sign.
