Swap USDT from Polygon to ETH on BNB Chain

Swap USDT from Polygon to ETH on BNB Chain. Tether USDT leaves Polygon. Binance-Peg ETH is what can arrive on BNB Chain. The word ETH here is a BEP-20, not gas, and not Ethereum WETH.

Sell 0xc2132D05D31c914a87C6611C10748AEb04B58e8F. Buy 0x2170Ed0880ac9A755fd29B2688956BD959F933F8. Native BNB is a different line. Polygonscan shows Tether. BscScan shows the peg. Chain id 56 blocks in about 3 seconds. Polygon is only the network you sign on.

Three assets people call ETH

Native ETH pays Ethereum. WETH is 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2. This route buys neither. It buys the BNB Chain peg. If your balance is on chain id 1, Etherscan is the wrong explorer and this page is the wrong route.

The peg will not start the next transaction

BNB pays chain id 56. If the goal was gas, buy the native label instead. Arriving with only 0x2170Ed0880ac9A755fd29B2688956BD959F933F8 leaves you unable to move it. That is the wrong output for a gas top-up.

Tether does not come along

BNB Chain USDT is 0x55d398326f99059fF775485246999027B3197955. This quote does not buy it. You leave the dollar peg and take pegged-ETH price exposure. Read the output before you approve 0xc2132D05D31c914a87C6611C10748AEb04B58e8F.

POL remains the source fee

Chain id 137 charges POL, about 2 second blocks. Those blocks are not the bridge. Leave POL. The destination fee, if you move the peg later, is BNB and is not included.

Frequently asked questions

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

Sell 0xc2132D05D31c914a87C6611C10748AEb04B58e8F. Buy 0x2170Ed0880ac9A755fd29B2688956BD959F933F8. XAUConnect compares live routes and lets your own wallet sign.

Does BscScan treat this peg as Ethereum?

The contract 0x2170Ed0880ac9A755fd29B2688956BD959F933F8 can be named like Ethereum and still be a BEP-20 on chain id 56. It is not native ETH and not WETH. BNB is the only gas coin there. Read the contract on BscScan, not the ticker alone. The name can say Ethereum and still be the peg.

Is Polygon USDT the same as BNB Chain USDT?

No. You sell 0xc2132D05D31c914a87C6611C10748AEb04B58e8F. BNB Chain Tether is 0x55d398326f99059fF775485246999027B3197955, and this route does not buy it. Polygonscan shows the debit. If you wanted to keep Tether, choose that output instead of the peg. Keeping a dollar peg means Tether or Circle, not this output. Pick one before you sign.

What pays fees after the peg arrives?

BNB, not the peg and not POL. The native label on chain id 56 is 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE. This quote does not buy it. About 3 second blocks are not a bridge finish time. Fund BNB separately if you need to transfer the peg. The peg itself never becomes gas.
