Swap WETH from Polygon to USDC on BNB Chain
Swap WETH from Polygon to USDC on BNB Chain. Polygon WETH leaves Polygon. Circle USDC is what can arrive on BNB Chain. You are not moving Ethereum WETH, and the USDC you receive uses 18 decimals.
Sell 0x7ceB23fD6bC0adD59E62ac25578270cFf1b9f619. Buy 0x8AC76a51cc950d9822D68b83fE1Ad97B32Cd580d. Gas on the source is POL. Gas on the destination is BNB, which this USDC cannot replace. Polygonscan and BscScan are the two records. BNB Chain will not treat this USDC as the fee coin.
Polygon WETH is not the peg and not mainnet WETH

Frequently asked questions
What is the best way to swap WETH from Polygon to USDC on BNB Chain?
Sell 0x7ceB23fD6bC0adD59E62ac25578270cFf1b9f619. Buy 0x8AC76a51cc950d9822D68b83fE1Ad97B32Cd580d. XAUConnect compares live routes and lets your own wallet sign.
Is this the Binance-Peg ETH token?
No. The peg is 0x2170Ed0880ac9A755fd29B2688956BD959F933F8. This route sells Polygon WETH at 0x7ceB23fD6bC0adD59E62ac25578270cFf1b9f619 and buys Circle USDC at 0x8AC76a51cc950d9822D68b83fE1Ad97B32Cd580d. ETH is not WETH. BscScan should show USDC, not the peg. The sell is Polygon WETH and the buy is 18 decimal Circle USDC. Nothing else is in this quote.
Why does the USDC integer look enormous?
BNB Chain USDC uses 18 decimals. Polygon WETH also uses 18, but the price is not one for one. Read the quote. BscScan's raw value is not a bonus. Polygonscan shows the WETH debit on chain id 137. POL pays that side. Compare human amounts on the quote, not the raw log.
Can I move the USDC with no BNB?
No. 0x8AC76a51cc950d9822D68b83fE1Ad97B32Cd580d is not gas. Native BNB is the label 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE on chain id 56. This route does not buy it. Keep BNB in the destination or the USDC waits. About 3 second blocks are not the bridge. BNB has to already be there if you want to transfer the USDC.
