Swap POL from Polygon to ETH on BNB Chain

Swap POL from Polygon to ETH on BNB Chain. Native POL leaves Polygon. Binance-Peg ETH is what can arrive on BNB Chain. You do not receive BNB, and you do not receive native ether.

Sell 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE, POL on chain id 137. Buy 0x2170Ed0880ac9A755fd29B2688956BD959F933F8. That peg is not WETH and cannot pay gas. Polygonscan shows the POL debit. BscScan shows the peg. You will need BNB already if you want to move it. BNB Chain charges that later fee in BNB, not in the peg.

Gas in, token out, gas still required

You spend POL, which is gas on Polygon, and receive a BEP-20 that is not gas on BNB Chain. If the job was to fund BNB, this route is wrong. The native label on chain id 56 is the BNB route.

WETH is not hiding in the peg

Ethereum WETH is 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2. ETH is not WETH. The peg is a third contract. Etherscan will not show this credit. BscScan will, under the peg address, not as native BNB.

Keep POL for the send

Wrapped POL at 0x0d500B1d8E8eF31E21C99d1Db9A6444d3ADf1270 is the wrong balance. Native POL pays the fee and is the asset. About 2 second blocks are chain id 137 only. Do not spend the last unit.

Volatile pair

POL against pegged ETH can move before you sign. Take the minimum or refresh. No finish time is published for the bridge. About 3 seconds is a BNB Chain block, visible later on BscScan.

Frequently asked questions

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

Sell 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE, POL on chain id 137. Buy 0x2170Ed0880ac9A755fd29B2688956BD959F933F8. XAUConnect compares live routes and lets your own wallet sign.

Does this arrival pay BNB Chain gas?

No. 0x2170Ed0880ac9A755fd29B2688956BD959F933F8 is the peg, not BNB. BNB is 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE on chain id 56, and this quote does not buy it. Keep BNB in the destination. BscScan should show the peg token, not a native credit. About 3 second blocks are not the bridge. Native BNB is a different quote entirely.

Is the source label the same coin as the peg?

No. 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE means POL on Polygon. The peg is a BEP-20 with its own contract. You do not approve POL. Polygonscan shows a native debit. If you are approving WMATIC, you are selling the wrong asset for this page. Wrapped POL will not complete this send.

What if I wanted native ETH on Ethereum?

Then leave this route. Ethereum is chain id 1, explorer Etherscan, blocks about 12 seconds, and the gas label there means ETH. This page ends on BNB Chain. ETH is not WETH, and the peg is not native ETH either. Start from the Ethereum output if that is the chain you need.
