Swap ETH from Arbitrum One to SOL on Solana

Swap ETH from Arbitrum One to SOL on Solana. Native ETH leaves Arbitrum One and the wrapped SOL mint is what can arrive.

Both gas coins are involved, and they are not the same object. Spend 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE on Arbitrum One, native ETH, not WETH. Arbiscan, chain id 42161, not Nova. Reserve a fee. The Solana mint is So11111111111111111111111111111111111111112. Solscan and Phantom. No ERC-20 approval. Not a 0x recipient. Slots near 400 milliseconds are not a bridge timer.

Two gas systems, one wrapped mint

ETH pays Arbitrum. SOL pays Solana. This quote sells the first and can credit the wrapped form of the second. So11111111111111111111111111111111111111112 is not native lamports until it is unwrapped. It is not the EVM sentinel, even though both represent a gas coin in casual speech. If you needed fee lamports specifically, confirm the unwrap in Phantom rather than assuming the mint spends itself.

Do not sell the last wei

The source asset is the source fee. Leave ETH. WETH is a different row. The SOL you hope to see cannot travel backward and pay chain id 42161. How cross-chain bridges work is the right picture for two runtimes. An EVM address on the receive line breaks the picture immediately.

A market between ETH and SOL

Neither asset is a stablecoin. The minimum on the wrapped mint is the bound, and it expires. Eighteen decimals on ETH do not map neatly onto SOL's nine decimals by eye. Use the quote. Refresh it. Nova is the wrong source chain while you do that reading.

Wrong if a dollar mint was the goal

Circle's Solana USDC and Tether's SPL USDT are other pages. This one is wrapped SOL. It is wrong for Arbitrum WETH holders, wrong for a local wrap that should stay on chain id 42161, and wrong for anyone watching Etherscan for a Solana mint.

Frequently asked questions

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

Both gas coins are involved, and they are not the same object. Spend 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE on Arbitrum One, native ETH, not WETH.

Is So111 the same as ETH because both are gas?

No. You spend native ETH, sentinel 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE, on Arbitrum One. You can receive wrapped SOL, mint So11111111111111111111111111111111111111112, in Phantom. Solscan is the explorer. Wrapped SOL is not an ERC-20. Native lamports pay Solana fees. There is no approve call on Solana. Confirm that address on the explorer before you sign, and refresh the quote if it has expired.

Why reserve ETH if the goal is SOL?

The signature happens on chain id 42161, which charges ETH. SOL cannot pay that fee, and it does not exist there. Leave a cushion. WETH will not substitute. A slot near 400 milliseconds on Solana does not pay Arbitrum gas. Nova is not the source.

Can my MetaMask address receive the SOL?

Not the 0x account. You need a Solana address from Phantom or a similar wallet. MetaMask's EVM account cannot hold the So111 mint. Watch the Solana wallet after you sign, not only the Arbitrum balance that decreases. Confirm that address on the explorer before you sign, and refresh the quote if it has expired.
