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

Approve 0x2170Ed0880ac9A755fd29B2688956BD959F933F8. BscScan lists that peg on chain id 56. Gas is BNB, blocks about 3 seconds. The peg is not BNB. Tether on Arbitrum One is 0xFd086bC7CD5C481DCC9C85ebE478A1C0b69FCbb9. Match it on Arbiscan. Chain id 42161, not Nova. ETH pays the fees there. USDT does not. The ARB token does not. Ethereum mainnet USDT is a different contract.

Approve the peg and keep BNB aside

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

Arbitrum Tether is its own contract

0xFd086bC7CD5C481DCC9C85ebE478A1C0b69FCbb9 is what Arbiscan should show. It is not Circle's native USDC and not mainnet USDT. Six decimals versus the peg's 18 is a display gap. Read the quote. Hold ETH in the same wallet or the USDT cannot be forwarded. Nova will stay empty.

Native USDC, ETH, and ARB are other pages

If the desk asked for Circle, this Tether payout is the wrong tool. If you needed ETH to pay gas, it is the wrong tool. If you meant to sell BNB, it is the wrong input. How bridges work is the wait, not a locked dollar amount.

BscScan for the peg, Arbiscan for Tether

Watch the peg leave on BscScan. Watch Tether arrive on Arbiscan, chain id 42161. A 3 second block is not a finish time. Read the minimum USDT before you sign. If the floor is poor, do not sign. Do not reuse a destination from a chat. Nova will not show this Tether, and ARB will not pay the fee.

Frequently asked questions

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

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 Arbitrum?

No. You send the peg 0x2170Ed0880ac9A755fd29B2688956BD959F933F8 and you receive Tether at 0xFd086bC7CD5C481DCC9C85ebE478A1C0b69FCbb9. BscScan shows the send. Arbiscan shows the USDT on chain id 42161, not Nova. ETH is a separate coin you need for gas. BNB paid only the source fee.

Is this the USDT contract from Ethereum mainnet?

No. Mainnet Tether lives on chain id 1. This contract is Arbitrum One only. Check Arbiscan, not Etherscan. If you paste a mainnet address and expect this USDT, the route is the wrong tool. Keep ETH beside the token after it arrives. The ARB token will not pay the fee.

Will the peg's 18 decimals match USDT one for one?

Do not compare raw integers. The peg uses 18 decimals and this 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.
