Swap WETH from Polygon to USDT on BNB Chain
Swap WETH from Polygon to USDT on BNB Chain. Polygon WETH leaves Polygon. Tether USDT is what can arrive on BNB Chain. The Tether you receive is the 18 decimal contract, not Ethereum's 6 decimal USDT.

POL pays chain id 137. See how to bridge assets between chains if a wrapped token and a stablecoin feel like one transfer.

Frequently asked questions
What is the best way to swap WETH from Polygon to USDT on BNB Chain?
Debit 0x7ceB23fD6bC0adD59E62ac25578270cFf1b9f619. Credit 0x55d398326f99059fF775485246999027B3197955. XAUConnect compares live routes and lets your own wallet sign.
Is 0x55d3 the same token I might hold on Ethereum?
No. Ethereum Tether is 0xdAC17F958D2ee523a2206206994597C13D831ec7 with 6 decimals. This route buys 0x55d398326f99059fF775485246999027B3197955 on chain id 56 with 18 decimals. You sell Polygon WETH at 0x7ceB23fD6bC0adD59E62ac25578270cFf1b9f619. BscScan and Polygonscan are separate. Etherscan is not in this hop. Eighteen decimals here are not the six decimals of Ethereum Tether.
What if I wanted Circle USDC?
Then do not use this page. Circle on BNB Chain is 0x8AC76a51cc950d9822D68b83fE1Ad97B32Cd580d. Tether and Circle are different issuers even when both say one dollar. Read the output contract before you approve WETH on chain id 137. Circle and Tether do not satisfy the same deposit instruction.
Why did the swap ask for POL if I am selling WETH?
Because chain id 137 takes POL for gas, not WETH. ETH is not WETH, and WETH is not POL. The native label 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE means POL on Polygon. Keep a remainder. The bridge itself has no finish time on this page. WETH cannot cover a shortfall of native POL.
