Swap BNB from BNB Chain to POL on Polygon

Swap BNB from BNB Chain to POL on Polygon. You send native BNB on BNB Chain and you receive native POL on Polygon.

Both sides use 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE. On BNB Chain, chain id 56, the marker is BNB. On Polygon, chain id 137, it is POL. BscScan shows the BNB leaving. Polygonscan shows the POL arriving. There is no ERC-20 approval on either gas coin. Blocks on BNB Chain are about 3 seconds. This is not WETH, not the ETH peg, and not a dollar token.

BNB leaves BNB Chain. POL is what can arrive on Polygon.

One placeholder, BNB leaving and POL arriving

The string is not a coin that hops. It means whichever gas coin the chain uses. You sell BNB and you buy POL. Both can move. The Binance-Peg ETH contract is not an input. If that is all you hold, this page will not take it. Leave some BNB, or the source fee fails.

Received POL can pay Polygon fees

Because the payout is the gas coin, you do not need old POL in the wallet for the new balance to be usable. That is the difference from landing in USDC, USDT, or WETH. Polygonscan will not show an ERC-20 page for this credit. Do not search the marker as if it had holders.

Dollar tokens and WETH if you did not want POL

Those payouts are other pages from the same BNB balance. This one is the wrong tool if a desk asked for Tether or Circle, or if a pool asked for Polygon WETH. The bridge guide is the hop, not a BNB to POL rate. Nothing freezes the amount.

Read the POL floor on a moving pair

The estimate and the minimum are different lines. Sign against the minimum. A 3 second block on chain id 56 does not freeze POL. Confirm the wallet network before the signature, then look for the result on Polygonscan with chain id 137 selected. If the floor is too small, do not sign.

Frequently asked questions

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

Both sides use 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE. On BNB Chain, chain id 56, the marker is BNB.

Why are the two addresses identical if BNB and POL differ?

0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE stands in for the native gas coin. BscScan's native coin on chain id 56 is BNB. Polygonscan's native coin on chain id 137 is POL. There is no ERC-20 approval on either side. The ETH peg on BNB Chain is a separate token and is not part of this route.

Do I need POL in the wallet before the swap?

No. The POL from this route can pay fees after it arrives. You do need BNB left on chain id 56 to pay the source fee. If you spend the entire BNB balance, the send cannot be mined and no POL is created. Polygonscan is where the native credit belongs.

Can I undo the swap if POL falls after I sign?

No. A confirmed BNB transfer is not reversed here, and the price is not insured. Read the minimum POL first. The 3 second block is only BNB Chain. It is not a promise about how much POL Polygonscan will show, or about when that credit appears.
