Swap ARB from Arbitrum One to USDT on Ethereum

Swap ARB from Arbitrum One to USDT on Ethereum. ARB leaves Arbitrum One and Tether USDT arrives here on Ethereum.

The governance token you sell is 0x912CE59144191C1204E64559FE8253a0e49E6548. Read it on Arbiscan. Chain id 42161, Arbitrum One, not Nova. It is not the gas coin. Keep native ETH, sentinel 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE, for the fee. Tether you can receive is 0xdAC17F958D2ee523a2206206994597C13D831ec7 on Ethereum. That is the contract to open on Etherscan. Chain id 1, about 12 seconds per block, and that block time is not a fill promise.

Ethereum USDT, including its approve quirk

0xdAC17F958D2ee523a2206206994597C13D831ec7 is Tether on Ethereum, six decimals. Receiving it does not require you to approve it. Spending it later might. That contract's approve function omits the boolean return some wallets expect, so a follow-up approval can throw a confusing warning. Verify allowance on Etherscan before repeating it. None of that changes the identity of the token: it is Tether, not Circle, and not the ARB you sold.

ARB allowance is the permission that matters

If the route has no allowance on 0x912CE59144191C1204E64559FE8253a0e49E6548, the wallet will ask for one on chain id 42161. Pay it in ETH. Do not grant that permission from a Nova session. Do not confuse ARB with Arbitrum WETH at 0x82aF49447D8a07e3bd95BD0d56f35241523fBab1. The tickers are unrelated. A governance balance and a wrapped ether balance can sit in the same wallet and only one of them funds this quote.

The dollar amount is a market

ARB does not redeem at a fixed USDT rate. Liquidity, fees, and price all sit in the minimum. When the quote expires, so does the number. Tether can trade a hair away from one dollar as well, so two moving pieces are possible. Read the USDT floor in whole tokens, remembering six decimals, and ignore raw integer comparisons with eighteen-decimal ARB. Ethereum is where that Tether balance would live.

Not a bridge of the ARB token itself

If the plan is to hold ARB on Ethereum, this route is wrong because the output is USDT. If the plan is Circle USDC or Maker DAI, it is also wrong. If the plan is native ETH or WETH on mainnet, it is wrong. If you only wanted USDT on Arbitrum One, the local Tether contract is 0xFd086bC7CD5C481DCC9C85ebE478A1C0b69FCbb9 and this page is aimed at a different chain.

Frequently asked questions

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

The governance token you sell is 0x912CE59144191C1204E64559FE8253a0e49E6548. Read it on Arbiscan. XAUConnect compares live routes and lets your own wallet sign.

Does this route move ARB to Ethereum unchanged?

No. ARB at 0x912CE59144191C1204E64559FE8253a0e49E6548 is what you sell on Arbitrum One. The asset that can arrive is Tether USDT at 0xdAC17F958D2ee523a2206206994597C13D831ec7 on Ethereum. You will not see an ARB balance on Etherscan from this quote. If governance on the destination was the goal, stop and pick a different output.

Why might a future USDT approval warn me?

Ethereum USDT at 0xdAC17F958D2ee523a2206206994597C13D831ec7 does not return a boolean from approve. Wallets sometimes flag that call even when the allowance updated. Read the allowance on Etherscan before you fire a second approval. This route's receive step does not need that approval. The approval you may sign now is for ARB on Arbitrum One.

What pays gas if I hold only ARB?

Nothing on this route. Gas is native ETH on chain id 42161, sentinel 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE. ARB cannot substitute. Add ETH on Arbitrum One before you approve 0x912CE59144191C1204E64559FE8253a0e49E6548. Arbitrum Nova is the wrong chain id for that ETH. The fee is not refunded as USDT. Confirm the address on the explorer before you sign.
