Swap USDT from BNB Chain to WETH on Arbitrum One

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

Approve 0x55d398326f99059fF775485246999027B3197955. BscScan lists that 18-decimal peg on chain id 56. Gas is BNB. Blocks are about 3 seconds. WETH is 0x82aF49447D8a07e3bd95BD0d56f35241523fBab1. Match it on Arbiscan, chain id 42161, not Nova and not Ethereum mainnet. The wrapper cannot pay gas. ETH has to be in the receiving wallet already. The ARB token cannot fill that gap.

USDT leaves BNB Chain. WETH is what can arrive on Arbitrum One.

Tether's peg in, Arbitrum's wrapper out

The contract you approve is only 0x55d398326f99059fF775485246999027B3197955. You are not spending BNB and you are not spending the USDC peg. The result is WETH, so you take ether price risk. If you wanted native ETH, native USDC, or ARB, stop. The approval itself spends BNB and does not credit Arbiscan.

This WETH address is One, not mainnet

0x82aF49447D8a07e3bd95BD0d56f35241523fBab1 will not match Ethereum's WETH page. Arbiscan is the right explorer. Nova is the wrong chain. Without native ETH on chain id 42161, the wrapper cannot move and cannot be unwrapped. USDT did not pay that ETH, and ARB will not pay it either.

Open the native ETH page if you need fees

Fee money is the gas coin, not this contract. Dollar payouts are the native USDC page. How cross-chain bridges work explains the wait. It is not a locked WETH price. If you never needed Arbitrum One, sell the peg on BNB Chain.

Three balances before this is usable

BNB on chain id 56 for the send. ETH on chain id 42161 for the next transaction. A minimum WETH you still accept. A 3 second source block does not supply the missing ETH. Sign only if that floor is enough. Recheck the Arbiscan address if one character looks wrong. The ARB token will not cover a missing ETH balance on chain id 42161.

Frequently asked questions

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

Approve 0x55d398326f99059fF775485246999027B3197955. BscScan lists that 18-decimal peg on chain id 56. XAUConnect compares live routes and lets your own wallet sign.

Will this WETH show up as spendable ETH?

No. Wallets list 0x82aF49447D8a07e3bd95BD0d56f35241523fBab1 apart from native ETH. Arbiscan does the same on chain id 42161. The peg you sent was 0x55d398326f99059fF775485246999027B3197955 on BscScan. If you needed fee ETH, use the native ETH route. Nova is not where this wrapper lands.

Do I approve WETH on Arbitrum before it arrives?

No. The first approval is for the BNB Chain peg, and it spends BNB. WETH may need its own approval later, when a pool asks for it, and that later approval spends ETH you must already hold. This page does not pre-approve anything on Arbitrum One. Chain id there is 42161.

What if I hold the USDC peg rather than this USDT?

This page will not take it. The USDC peg has its own route to Arbitrum WETH. Approving the wrong contract does not start the swap. Check 0x55d398326f99059fF775485246999027B3197955 on BscScan. The payout stays 0x82aF49447D8a07e3bd95BD0d56f35241523fBab1 only on this route. Check BscScan first.
