Swap ETH from Arbitrum One to USDT on Solana

Swap ETH from Arbitrum One to USDT on Solana. Native ETH leaves Arbitrum One and SPL USDT arrives on Solana.

Spend the sentinel 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE on Arbitrum One, native ETH, not WETH. Chain id 42161, Arbiscan, not Nova. Leave gas. Receive Es9vMFrzaCERmJfrF4H2FYD4KCoNkY11McCe8BenwNYB. Solscan shows that Tether mint. Phantom holds it. No ERC-20 approval on Solana. Do not use a 0x recipient. Slots near 400 milliseconds are not a credit promise.

Diagram for Swap ETH from Arbitrum One to USDT on Solana
ETH leaves Arbitrum One. USDT is what can arrive on Solana.

Tether's mint, Phantom's account

Es9vMFrzaCERmJfrF4H2FYD4KCoNkY11McCe8BenwNYB is not 0xFd086bC7CD5C481DCC9C85ebE478A1C0b69FCbb9 and not Ethereum's 0xdAC17F958D2ee523a2206206994597C13D831ec7. Same issuer family, different runtime. Solscan is the check. An exchange page that says ERC-20 USDT wants an EVM chain and will not see this SPL balance. The deposit instructions have to say Solana.

Reserve ETH, then change wallets

The max button on Arbitrum ETH will starve the fee. WETH is not sold. After you sign, the thing to watch is Phantom, not the EVM wallet you signed with. Solana will not display a 0x transaction as an SPL credit. If you never open the Solana wallet, you will think the route failed.

No destination approval, still a destination fee

You do not approve the USDT mint. You may still need native SOL so the token account can be used. Wrapped SOL at So11111111111111111111111111111111111111112 is not included. The minimum USDT is a price against ETH. Refresh it. Nova cannot host the source signature.

Wrong asset if you wanted Circle or SOL

Circle's Solana mint is a different page. Wrapped SOL is a different page. This one sells ETH for Tether's SPL mint. It is wrong for WETH holders, wrong for X-Chain style confusion from other networks, and wrong for any recipient that is not a Solana address. Before you sign, compare 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE with Es9vMFrzaCERmJfrF4H2FYD4KCoNkY11McCe8BenwNYB on their explorers and stop if either address on the quote differs. A stale minimum is a reason to ask for a fresh quote rather than signing the old one. Sign only on the source chain id named in this article, with the wallet network checked.

Frequently asked questions

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

Spend the sentinel 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE on Arbitrum One, native ETH, not WETH. Chain id 42161, Arbiscan, not Nova.

Is Solana USDT the Arbitrum USDT contract?

No. The mint is Es9vMFrzaCERmJfrF4H2FYD4KCoNkY11McCe8BenwNYB, on Solscan. Arbitrum Tether is 0xFd086bC7CD5C481DCC9C85ebE478A1C0b69FCbb9, and you are not spending it. You spend native ETH on chain id 42161. Phantom receives the SPL mint. There is no ERC-20 approval on Solana. Confirm that address on the explorer before you sign, and refresh the quote if it has expired.

Where should I look after I sign?

In Phantom, at the Solana address you entered, and on Solscan for that mint. The Arbitrum wallet will show ETH leaving. It will not show the USDT credit. A 0x destination cannot hold the mint. A slot near 400 milliseconds is not a reason to watch Etherscan for the result.

Does this include SOL for fees?

No. The output is the USDT mint, not So11111111111111111111111111111111111111112. Native SOL pays Solana fees. You also must reserve ETH on Arbitrum because the sentinel balance is both the asset and the fee. WETH will not replace that reserve. Confirm that address on the explorer before you sign, and refresh the quote if it has expired.
