Swap SOL from Solana to ETH on Arbitrum One

Swap SOL from Solana to ETH on Arbitrum One. SOL leaves Solana, and native ETH is what can arrive to pay gas on Arbitrum One. The two fee coins do not share a wallet.

SOL is So11111111111111111111111111111111111111112 in the quote, the wrapped mint. Phantom signs, Solscan shows it, native SOL pays the source fee, and there is no ERC-20 approval. ETH is 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE on chain id 42161, not Nova. Arbiscan shows the native row. This is not WETH, not mainnet ETH on chain id 1, about 12 second blocks, Etherscan, and not WBTC.

Wrapped SOL in, native ETH out, nothing imported

Do not paste the mint into an EVM box and do not import the sentinel as a token. Read the ETH line on chain id 42161. If you sell every native SOL, Phantom cannot pay for the sale. The ETH you want cannot pay that Solana fee in advance. WETH at 0x82aF49447D8a07e3bd95BD0d56f35241523fBab1 is the wrapper route if a contract refuses native ETH.

Mainnet and Nova are the two wrong maps

A request for chain id 1 gas is a different bridge. A wallet on Nova will not show this ETH. Arbitrum One is the only arrival. About 12 second blocks describe Ethereum, not this hop. WBTC is not delivered, and WBTC is not native bitcoin. If someone asked for bitcoin or for mainnet ether, stop.

Solscan empty is not Arbiscan full

The debit can complete while the credit is still in the bridge. This page will not clock that gap. Do not sign a second time because Phantom dropped and MetaMask, on the wrong network, shows nothing. Switch to 42161 and watch the destination address. There is no ERC-20 approval on the mint to undo.

Buy this ETH only for Arbitrum transactions

If you need SOL fees, selling SOL is backwards. If you need USDC or USDT, a dollar route is calmer. If you need ARB, you are buying a governance token, not gas. The minimum ETH should cover the L2 actions you already intend. Refuse a floor that leaves you short on the chain you just paid to enter.

Frequently asked questions

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

SOL is So11111111111111111111111111111111111111112 in the quote, the wrapped mint. Phantom signs, Solscan shows it, native SOL pays the source fee, and there is no ERC-20 approval.

Why are the SOL and ETH addresses different styles?

SOL is the wrapped mint So11111111111111111111111111111111111111112 on Solscan, held in Phantom, with no ERC-20 approval. ETH is 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE on Arbitrum One, chain id 42161, shown on Arbiscan. Native SOL still pays the source fee. The balances cannot pay each other's chains. Confirm the contract on the explorer before you sign.

Can this ETH pay Ethereum mainnet?

No. Mainnet is chain id 1, about 12 second blocks, explorer Etherscan. This ETH pays Arbitrum One, not Nova. If mainnet gas was the goal, this route is the wrong destination. Leave enough SOL in Phantom that the source transaction can still be signed. Keep the destination gas token or the arrival cannot move.

What if the contract wants WETH?

Use the WETH route. Native ETH will not match 0x82aF49447D8a07e3bd95BD0d56f35241523fBab1 until you wrap, and wrapping needs ETH for gas. If the ABI names the wrapper, this page is incomplete. Check Arbiscan for whichever asset you chose to receive. The quote minimum is the floor, and a thin floor is a reason to stop.
