Swap ETH from Arbitrum One to USDT on BNB Chain

Swap ETH from Arbitrum One to USDT on BNB Chain. Native ETH leaves Arbitrum One and BSC USDT arrives on BNB Chain.

The spend is native ETH on Arbitrum One, sentinel 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE. Not WETH. Chain id 42161, Arbiscan, not Nova. Reserve gas. The receive contract is 0x55d398326f99059fF775485246999027B3197955 on BNB Chain, eighteen decimals. BscScan is the explorer. That is not six-decimal Ethereum Tether. Chain id 56 charges BNB for gas. Blocks are about 3 seconds, and the bridge does not inherit that as a deadline.

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

BSC USDT uses a different unit

Ethereum Tether, 0xdAC17F958D2ee523a2206206994597C13D831ec7, has six decimals and lives on chain id 1. This route can credit 0x55d398326f99059fF775485246999027B3197955 on chain id 56, with eighteen decimals. A wallet that imports the Ethereum address onto BNB Chain will not see this balance. Add the BscScan contract explicitly. Compare whole USDT on the quote with the ETH you are selling, and expect a market price, not a fixed redeem.

Leave ETH behind on the way out

Selling the gas coin means the max button is a trap. Keep enough native ETH for the transaction on chain id 42161. Wrapped ether at 0x82aF49447D8a07e3bd95BD0d56f35241523fBab1 is a separate balance and will not be debited. If you only hold WETH, switch to a WETH route or unwrap first and still reserve a fee.

Destination gas is a different ticker

USDT on BNB Chain does not pay fees. BNB does. This output is the token contract, not the sentinel, so you do not receive the fee coin. BNB Chain pages are the right place to remember chain id 56 before you paste a receive address from an exchange that only accepts a different USDT deployment.

Wrong for pegged ETH, BNB, or Circle USDC

You will not receive 0x2170Ed0880ac9A755fd29B2688956BD959F933F8. You will not receive native BNB. You will not receive Binance-Peg USDC at 0x8AC76a51cc950d9822D68b83fE1Ad97B32Cd580d. You will not receive Arbitrum Tether. The page is wrong on Nova and wrong if the goal was to keep ETH exposure rather than sell it for a dollar token.

Frequently asked questions

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

The spend is native ETH on Arbitrum One, sentinel 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE. Not WETH.

Can I import Ethereum USDT on BNB Chain and see this balance?

No. Ethereum USDT is 0xdAC17F958D2ee523a2206206994597C13D831ec7. This route names 0x55d398326f99059fF775485246999027B3197955 on chain id 56, eighteen decimals. Check BscScan. You spend native ETH, sentinel 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE, on Arbitrum One. The contracts are not substitutes. Confirm that address on the explorer before you sign, and refresh the quote if it has expired.

Does the route include BNB for the next transfer?

No. Gas on BNB Chain is native BNB. The output is a USDT contract, so a wallet with zero BNB can hold the tokens and still fail to send them. You must keep ETH on chain id 42161 to sign the sell. About 3 seconds is a block time, not a promise that both gas gaps are solved.

What if the wallet shows WETH instead of ETH?

Then this is the wrong page. WETH is 0x82aF49447D8a07e3bd95BD0d56f35241523fBab1. This quote spends the native sentinel on chain id 42161, not Nova. Unwrap only if you intend to sell ETH, and leave a fee. Otherwise open the WETH version of the route so the contract you hold is the one debited.
