Swap USDT from Solana to ETH on Arbitrum One

Swap USDT from Solana to ETH on Arbitrum One. Tether's SPL mint leaves Solana, and native ETH is what can arrive to pay gas on Arbitrum One, not on Nova and not on mainnet.

The mint is Es9vMFrzaCERmJfrF4H2FYD4KCoNkY11McCe8BenwNYB. Phantom and Solscan handle it with no ERC-20 approval. ETH is 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE on chain id 42161. Arbiscan shows the native balance. WETH is 0x82aF49447D8a07e3bd95BD0d56f35241523fBab1 and is a different route. Ethereum mainnet is chain id 1, about 12 second blocks, Etherscan. WBTC is not an output and is not native bitcoin.

The sentinel means L2 gas, not a token you import

Close any screen that treats 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE as an ERC-20. Read the ETH row on chain id 42161. If the app wants WETH, this page stops short. If the app wants mainnet gas, this page fills the wrong tank. Nova is a third miss. ARB, the governance token, will not substitute for the fee you are trying to buy.

Keep SOL, because the ETH is not here yet

Tether's mint does not pay Phantom. Native SOL does. A zero SOL balance ends the hop before Arbiscan matters. There is no allowance to revoke. MetaMask cannot show the mint leaving. Arbitrum One is where you look afterward, with an EVM wallet. The ETH you receive is the budget for the L2 actions that follow.

Do not borrow Ethereum's 12 second block as a timer

That cadence is chain id 1. Arbitrum One has its own blocks, and the bridge has a wait this page will not name. Solscan can show the mint gone while the ETH row is still old. Wait on the destination address. A second signature sells more Tether. Confirm the wallet is not sitting on Nova while you refresh.

A stable route is calmer when fees were not the shortage

USDT to USDC keeps Circle on Arbitrum. USDT to WETH buys the wrapper. USDT to ARB buys governance risk. This page buys ETH. Take ether's price only if the minimum still covers the gas you need. Otherwise keep the dollar, on Solana or on Arbitrum, and do not cross for a fee coin you will not use.

Frequently asked questions

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

The mint is Es9vMFrzaCERmJfrF4H2FYD4KCoNkY11McCe8BenwNYB. Phantom and Solscan handle it with no ERC-20 approval.

Is the arrival WETH or native ETH on Arbitrum One?

Native ETH, quoted as 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE on chain id 42161, not Nova. WETH is 0x82aF49447D8a07e3bd95BD0d56f35241523fBab1. Tether's mint left Solana. Check the ETH row on Arbiscan. If a contract wants the wrapper, this route is the wrong one. Switch the wallet to the destination chain before you judge the balance.

Will this ETH pay mainnet or Nova fees?

No. It pays Arbitrum One only. Ethereum is chain id 1, about 12 second blocks, explorer Etherscan. Nova is separate. SOL paid the Phantom side. There is no ERC-20 approval on Es9vMFrzaCERmJfrF4H2FYD4KCoNkY11McCe8BenwNYB. Keep SOL so the mint can leave. Do not send a second time while the first transfer is still open.

When is buying ETH from Tether the wrong job?

When you needed USDC, ARB, or WETH, or when the empty gas tank is on Ethereum mainnet. This page is for Arbitrum One fees. Read the minimum ETH and skip the quote if that floor will not cover the transactions you already have waiting. Confirm the contract on the explorer before you sign.
