Swap ETH from BNB Chain to USDT on Polygon

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

Approve 0x2170Ed0880ac9A755fd29B2688956BD959F933F8. BscScan lists that peg on chain id 56. Gas is BNB, blocks about 3 seconds. The peg is not BNB. Tether on Polygon is 0xc2132D05D31c914a87C6611C10748AEb04B58e8F. Match it on Polygonscan. Chain id 137. POL pays the fees there. USDT does not. Ethereum USDT is a different contract on a different explorer.

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

Approve the peg, leave BNB for the fee

The ETH ticker on BNB Chain is 0x2170Ed0880ac9A755fd29B2688956BD959F933F8. This route will not spend your BNB balance except as gas. If the peg balance is zero, stop. Native ETH on Ethereum is not an input either. The approval is a BNB Chain transaction, chain id 56, and it does not credit Polygon by itself.

Polygon Tether is its own contract

0xc2132D05D31c914a87C6611C10748AEb04B58e8F is what Polygonscan should show. It is not Circle's native USDC and not Ethereum USDT. Six decimals versus the peg's 18 is a display gap, not a missing fee. Read the quote. Hold POL in the same wallet or the USDT cannot be forwarded.

Native USDC, POL, and WETH are other pages

If the desk asked for Circle, this Tether payout is the wrong tool. If you needed POL to pay gas, it is the wrong tool. If you meant to sell BNB, it is the wrong input. How bridges work is the background for the wait. No USDT figure is promised.

BscScan out, Polygonscan in

Watch the peg leave on BscScan. Watch Tether arrive on Polygonscan. Etherscan is the wrong site for both. A 3 second BNB Chain block is not a Polygon finish time. Read the minimum USDT before you sign. If the floor is poor, do not sign, and do not reuse a destination address from a chat. POL still has to be waiting in that wallet.

Frequently asked questions

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

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

Does the ETH name mean I receive ETH on Polygon?

No. You send the peg 0x2170Ed0880ac9A755fd29B2688956BD959F933F8 and you receive Tether at 0xc2132D05D31c914a87C6611C10748AEb04B58e8F. BscScan shows the send. Polygonscan shows the USDT. POL is a separate coin you need for gas on chain id 137. BNB paid only the source fee. POL is extra.

Is this the USDT contract from Ethereum?

No. Ethereum Tether lives on chain id 1. This mint is Polygon only, 0xc2132D05D31c914a87C6611C10748AEb04B58e8F. Check Polygonscan, not Etherscan. If you paste an Ethereum address and expect this USDT, the route is the wrong tool. Keep POL beside the token after it arrives.

Will the 18-decimal peg match USDT one for one on-chain?

Do not compare raw integers. The peg uses 18 decimals and Polygon USDT uses 6. The quote speaks in whole tokens. The minimum there is the floor, and this page does not promise a price. BNB Chain blocks near 3 seconds do not lock that minimum.
