Swap USDT from BNB Chain to WETH on Ethereum

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

Approve 0x55d398326f99059fF775485246999027B3197955 on BNB Chain. BscScan is the explorer for that 18-decimal peg. Chain id 56, gas in BNB, blocks about 3 seconds. WETH is 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2 on Ethereum. Match it on Etherscan. It is not native ETH. Chain id 1 still charges gas in ETH, with blocks about 12 seconds. The wrapper you receive cannot pay that charge.

USDT leaves BNB Chain. WETH is what can arrive on Ethereum.

The payout cannot pay the fee

WETH at 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2 is an ERC-20. Ethereum gas is a separate native balance. If the receiving wallet has no ETH, the WETH arrives and then sits. This is the central way to misuse the page. The source side is simpler: BNB pays the approval of the Tether peg, and the peg itself is not BNB.

Wrapper contract versus the peg you sent

The input 0x55d398326f99059fF775485246999027B3197955 is Tether's peg, not Binance-Peg ETH and not USDC. The output is canonical WETH, not the 0xEeee marker. Etherscan and BscScan will never show a single combined balance. Read whole tokens on the quote so the 18-decimal peg does not get compared raw with WETH.

Open the native ETH page if you need gas

If the reason for the hop was fee money on Ethereum, native ETH is the right payout and this page is the wrong tool. USDC and DAI pages are the right tool when you wanted a dollar token. How cross-chain bridges work is background for the wait. It is not a locked WETH price.

Two networks, one floor

Sign the approval on chain id 56 only after you accept the minimum WETH. BNB Chain can include the transaction in about 3 seconds and the route can still be unfinished. Ethereum's 12 second blocks are another fact, not a timer for the bridge. Keep ETH waiting on the destination. Do not spend your last BNB on a larger peg balance.

Frequently asked questions

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

Approve 0x55d398326f99059fF775485246999027B3197955 on BNB Chain. BscScan is the explorer for that 18-decimal peg.

Will this WETH show up as spendable ETH in my wallet?

No. Wallets list WETH at 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2 apart from the native ETH balance. Etherscan does the same. The native coin pays gas. The token you sent was 0x55d398326f99059fF775485246999027B3197955 on BscScan. If you needed fee ETH, use the native ETH route instead of this one.

Do I approve WETH on Ethereum before it arrives?

No. The approval you need first is for the BNB Chain peg, and it spends BNB. WETH may need its own approval later, when you want to use it in a pool, and that later approval spends ETH you must already hold. This page does not pre-approve anything on Ethereum. Chain id on the destination is 1.

What if I hold USDC on BNB Chain and not this USDT peg?

This page will not take it. USDC is 0x8AC76a51cc950d9822D68b83fE1Ad97B32Cd580d and has its own route to WETH. Approving the wrong peg does not start the swap. Check 0x55d398326f99059fF775485246999027B3197955 on BscScan before you sign. The payout contract does not change to match whatever stablecoin you happen to hold.
