Swap ETH from BNB Chain to POL on Polygon

Swap ETH from BNB Chain to POL on Polygon. You send Binance-Peg ETH on BNB Chain and you receive native POL on Polygon.

Approve 0x2170Ed0880ac9A755fd29B2688956BD959F933F8. BscScan shows that peg on chain id 56. Gas for the approval is BNB, blocks about 3 seconds. The peg is not the gas coin. On Polygon the marker 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE means POL. Polygonscan shows the native credit, chain id 137. That POL can pay later fees. It is not WETH and not a dollar token.

The peg is sold, BNB only pays

This input is 0x2170Ed0880ac9A755fd29B2688956BD959F933F8 and nothing else. A wallet full of BNB and empty of the peg cannot use the page. You still need some BNB so the approval is mined. The trade takes POL price risk. If you wanted USDC or USDT on Polygon, you are on the wrong payout.

POL is the native marker on chain id 137

0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE is not an ERC-20 on Polygonscan. Here it means POL. The same marker on BNB Chain would mean BNB, which is not what you are sending. The received POL can pay Polygon fees, so you do not need a prior POL balance for the credit to be usable.

WETH and dollar tokens if POL was a mistake

Polygon WETH is a contract, not this marker. Native USDC and USDT are contracts too. Open those pages if that is what the destination needs. The bridge guide explains the hop in general. It does not lock the POL amount, and a fast BNB Chain block is not a completion time.

Switch the wallet to Polygon before you look

BscScan will show the peg leaving chain id 56. The POL will not appear there. Set the wallet to chain id 137 and use Polygonscan. Read the minimum POL before you sign. If you would not hold that much POL against the peg you are selling, do not sign.

Frequently asked questions

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

Approve 0x2170Ed0880ac9A755fd29B2688956BD959F933F8. BscScan shows that peg on chain id 56. XAUConnect compares live routes and lets your own wallet sign.

Does the ETH ticker on BNB Chain turn into POL one for one?

No. You sell the peg at 0x2170Ed0880ac9A755fd29B2688956BD959F933F8, and the quote prices it into POL. The destination marker is 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE, which means POL on Polygonscan. Nothing locks that price. Gas on the send is BNB, on chain id 56. BNB is only the fee.

Will I still need extra POL after this route?

The payout is POL, so it can pay fees once it arrives. You do not need a prior POL balance for that. You do need BNB to approve the peg. Polygonscan shows a native credit, not WETH. If you wanted WETH specifically, this page is the wrong tool.

Can I send BNB on this page and still get POL?

Not on this page. BNB uses the gas-coin marker as the input and has a separate route. This page approves 0x2170Ed0880ac9A755fd29B2688956BD959F933F8 only. If BscScan shows BNB and no peg, stop. Signing an empty approval does not start the swap. Look twice.
