Swap WETH from Polygon to BNB on BNB Chain

Swap WETH from Polygon to BNB on BNB Chain. Polygon WETH leaves Polygon. Native BNB is what can arrive on BNB Chain. Ether exposure becomes the gas coin on chain id 56.

You sell 0x7ceB23fD6bC0adD59E62ac25578270cFf1b9f619. You buy 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE, meaning BNB, not WBNB and not the pegged ETH token. Polygonscan shows WETH leaving. BscScan shows native BNB. POL pays the source. BNB Chain is where that native credit can pay later fees.

Diagram for Swap WETH from Polygon to BNB on BNB Chain — WETH leaves Polygon. BNB is what can arrive on BNB Chain.

WBNB and the peg are other jobs

WBNB is 0xbb4CdB9CBd36B01bD1cBaEBF2De08d9173bc095c. Pegged ETH is 0x2170Ed0880ac9A755fd29B2688956BD959F933F8. This route buys neither. If a contract wants one of those, you picked the wrong output. Native BNB is the spendable gas coin.

Do not approve the gas label

There is no contract behind 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE. On BNB Chain it means BNB. An approval popup for that string is not this route. BscScan should show a native credit.

WETH is not the Polygon fee

Chain id 137 charges POL. Selling WETH does not replace that. Leave POL. About 2 second blocks are not the bridge clock. A wallet of only WETH cannot send.

BNB and the peg can both reprice

WETH against BNB is not a stable pair. The minimum on the quote is the floor. Let an expired quote die and request another. No finish time is stated here.

Frequently asked questions

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

You sell 0x7ceB23fD6bC0adD59E62ac25578270cFf1b9f619. You buy 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE, meaning BNB, not WBNB and not the pegged ETH token.

Does 0xEeee mean WETH on the destination?

No. On BNB Chain, 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE means native BNB. WETH is what you sell on Polygon, at 0x7ceB23fD6bC0adD59E62ac25578270cFf1b9f619. ETH is not WETH, and BNB is not WBNB. BscScan shows the native credit. You do not approve the label. WBNB is a later wrap, only after this native credit.

I need the Binance-Peg ETH token, not BNB. Is this it?

No. The peg is 0x2170Ed0880ac9A755fd29B2688956BD959F933F8 and cannot pay gas. This page pays BNB. If you sign here, you will not see the peg on BscScan. Switch outputs before you approve Polygon WETH. POL is still the source fee. The peg and native BNB are different outputs.

Can I receive WBNB directly?

Not from this quote. WBNB is 0xbb4CdB9CBd36B01bD1cBaEBF2De08d9173bc095c. You would wrap native BNB afterward, which spends a little BNB. If the quote you wanted names WBNB, you are on the wrong page. Polygonscan only shows the WETH debit. Do not expect WBNB to arrive from this page.
