Swap ETH from Arbitrum One to USDT on Ethereum

Swap ETH from Arbitrum One to USDT on Ethereum. Native ETH leaves Arbitrum One and Tether USDT arrives on Ethereum.

Spend the gas sentinel 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE on Arbitrum One, chain id 42161. That is native ETH, not WETH, and Arbiscan is the explorer for the network you are leaving. Keep some of that ETH for the fee. The contract you can receive is Tether at 0xdAC17F958D2ee523a2206206994597C13D831ec7 on Ethereum. Open it on Etherscan. Chain id 1 produces blocks about every 12 seconds. That cadence is not a promise about USDT showing up.

Ethereum Tether is a fussy contract

0xdAC17F958D2ee523a2206206994597C13D831ec7 is the long-standing Tether deployment on Ethereum, six decimals. It does not behave like a textbook ERC-20 in every wallet because its approve function does not return a boolean. Receiving it is still a normal credit. Trouble shows up later, when you try to spend that USDT and a wallet misreads the approval. If a later spend looks stuck, check the allowance on Etherscan before you blame the bridge.

Leave gas behind on Arbitrum One

You are selling native ETH, which is also the fee token on chain id 42161. The full balance is not available to the quote. WETH at 0x82aF49447D8a07e3bd95BD0d56f35241523fBab1 will not be touched, and it will not pay the fee either. Nova uses a different chain id. If the wallet is pointed there, you are not on the network this route debits, no matter what the ETH ticker says.

Price can move while the quote sits

ETH against USDT is a market, not a fixed redemption. The minimum on the quote is your bound. When the quote goes stale, the bound goes with it. Request a new quote and read the new USDT floor. Tether aims at a dollar. ETH does not. A quiet hour and a violent hour are different trades even when the contract addresses stay the same. Do not sign a minimum you have not reread.

Not Circle, not DAI, not wrapped ether

This page is wrong if you wanted Circle USDC at 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 or Maker DAI at 0x6B175474E89094C44Da98b954EedeAC495271d0F. It is wrong if you wanted WETH on Ethereum, and wrong if you wanted to keep native ETH and only move chains. Ethereum will show Tether, not a gas balance, as the asset this quote can add.

Frequently asked questions

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

Spend the gas sentinel 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE on Arbitrum One, chain id 42161. That is native ETH, not WETH, and Arbiscan is the explorer for the network you are leaving.

Which USDT address should Etherscan show?

0xdAC17F958D2ee523a2206206994597C13D831ec7. That is Tether on Ethereum, six decimals. Arbitrum Tether, 0xFd086bC7CD5C481DCC9C85ebE478A1C0b69FCbb9, is a different contract and is not the receive asset here. You are spending native ETH, sentinel 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE, on Arbitrum One. Match both sides before you approve anything later. Confirm that address on the explorer before you sign, and refresh the quote if it has expired.

Why might a later USDT approval look odd?

The Ethereum USDT contract's approve call does not return a boolean the way many ERC-20s do. Some wallets show a warning even when the allowance was set. Check the allowance on Etherscan for 0xdAC17F958D2ee523a2206206994597C13D831ec7 before you send a second approval. Receiving USDT on this route does not itself require that approval.

Is this the same as wrapping ETH on Arbitrum?

No. Wrapping locally would mint WETH at 0x82aF49447D8a07e3bd95BD0d56f35241523fBab1 and you would stay on Arbitrum One. This route sells native ETH and can credit Tether USDT on Ethereum, chain id 1. If you wanted WETH on Ethereum, this is the wrong output. Keep fee ETH on chain id 42161 so the sell can be signed.
