Swap WETH from Polygon to ETH on BNB Chain

Swap WETH from Polygon to ETH on BNB Chain. Polygon WETH leaves Polygon. Binance-Peg ETH is what can arrive on BNB Chain. Both are called ETH by someone, and they are different contracts on different chains.

Sell 0x7ceB23fD6bC0adD59E62ac25578270cFf1b9f619. Buy 0x2170Ed0880ac9A755fd29B2688956BD959F933F8. Ethereum WETH at 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2 is not either side. The peg does not pay gas. BNB does. Polygonscan shows the WETH debit. BscScan shows the peg. How cross-chain bridges work separates a local wrap from this hop.

Same nickname, two ledgers

Polygon WETH is not the BEP-20 peg, and neither is mainnet WETH. ETH is not WETH. If you wanted native BNB, the gas label is the right output and this page is wrong. If you wanted to stay on Polygon, do not bridge.

The peg cannot pay chain 56

0x2170Ed0880ac9A755fd29B2688956BD959F933F8 sits in the token list. Fees come from BNB. A destination wallet with no BNB can receive the peg and then stall. About 3 second blocks are the chain, not the bridge finish.

POL still leaves Polygon

Approving 0x7ceB23fD6bC0adD59E62ac25578270cFf1b9f619 does not pay chain id 137. POL does. Blocks there are about 2 seconds. Leave a remainder. WETH is not a fee token on Polygon.

Price on both sides

WETH and the peg both track ether, but the quote is not a promise of one for one after fees. Read the minimum. Refresh if it expires. Etherscan is the wrong explorer for both the debit and the credit.

Frequently asked questions

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

Sell 0x7ceB23fD6bC0adD59E62ac25578270cFf1b9f619. Buy 0x2170Ed0880ac9A755fd29B2688956BD959F933F8. XAUConnect compares live routes and lets your own wallet sign.

Is this an unwrap of WETH into ETH?

No. Unwrapping, where it exists, stays on one chain. Polygon has no native ETH. This route sells 0x7ceB23fD6bC0adD59E62ac25578270cFf1b9f619 and can credit the peg 0x2170Ed0880ac9A755fd29B2688956BD959F933F8 on chain id 56. ETH is not WETH. BscScan shows the peg, not a native ETH balance. A native ETH line will not appear there.

Will the peg pay my next BNB Chain transaction?

No. Gas is BNB, the native label 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE on chain id 56. This quote does not buy that label. Keep BNB in the destination or the peg cannot move. About 3 second blocks describe BNB Chain only, not the bridge. Fund BNB in that wallet before the peg has to move.

What if I hold Ethereum WETH?

Then this page is the wrong route. Ethereum WETH is 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2 on chain id 1. You must be on Polygon, chain id 137, holding 0x7ceB23fD6bC0adD59E62ac25578270cFf1b9f619, with POL for gas. Polygonscan is the debit explorer. Mainnet WETH will not sell on this page. Stay on Polygon for the debit.
