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

Spend 0x912CE59144191C1204E64559FE8253a0e49E6548 on Arbitrum One. Arbiscan, chain id 42161, not Nova. Hold ETH, because ARB is not gas. The mint is So11111111111111111111111111111111111111112. Solscan and Phantom. Wrapped SOL is not an ERC-20, so you do not approve it. A 0x recipient cannot hold it. Slots near 400 milliseconds are not a fill promise.

A governance sale into wrapped SOL

People open this page when they hold ARB and need SOL in Phantom. The output is the wrapped mint, which wallets often label SOL. Native lamports are what pay fees, so you may unwrap after arrival. You do not receive an ARB mint. Voting weight leaves with the tokens you sell. If a proposal is soon, keep the ARB and fund SOL another way.

Address format is the first filter

Phantom's address is the recipient. The Arbitrum address is only the signer on chain id 42161. Mixing them strands the intent before a route exists. How cross-chain bridges work is useful background, and it still assumes you can tell an SPL mint from an ERC-20. So111 will not appear on Arbiscan.

ETH for the approval, then a market quote

0x912CE59144191C1204E64559FE8253a0e49E6548 may need allowance, paid in ETH. The minimum wrapped SOL expires when the quote expires. ARB and SOL both float. Do not treat equal-looking decimals as a one-for-one redeem. SOL uses nine decimals. ARB uses eighteen. Read the quote.

Wrong when ARB is the asset you must keep

Stop if you are relocating the governance token. Stop for Circle USDC or SPL USDT. Stop for Nova. Stop if the wallet balance is WETH or native ETH. Stop if you expected an ERC-20 approval on Solana. That call does not exist for this mint. Before you sign, compare 0x912CE59144191C1204E64559FE8253a0e49E6548 with So11111111111111111111111111111111111111112 on their explorers and stop if either address on the quote differs. Keep the source fee token in the wallet after you choose the trade size. Gas on the source chain is separate from the asset you hope to receive.

Frequently asked questions

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

Spend 0x912CE59144191C1204E64559FE8253a0e49E6548 on Arbitrum One. Arbiscan, chain id 42161, not Nova. XAUConnect compares live routes and lets your own wallet sign.

Is the output ARB on Solana or SOL?

Wrapped SOL. The mint is So11111111111111111111111111111111111111112, checked on Solscan, held in Phantom. You sell ARB at 0x912CE59144191C1204E64559FE8253a0e49E6548. There is no ERC-20 approval on Solana. Native lamports, not the wrapped mint alone, pay fees. A 0x address cannot receive the mint. Confirm that address on the explorer before you sign, and refresh the quote if it has expired.

Does this preserve my ARB vote?

No. Sold tokens leave chain id 42161. They are not bridged as ARB and they do not vote from Phantom. Keep what you need. The credit is wrapped SOL, which has no ARB governance rights. Nova is not the network that holds the remainder. Confirm the address on the explorer before you sign.

Why is ETH required to buy SOL?

Because the signature is on Arbitrum One, and that chain charges ETH, sentinel 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE. ARB cannot pay it. The SOL mint cannot pay it. A slot near 400 milliseconds is a Solana fact, not a waiver of the source fee. Fund ETH, then watch Phantom for So111.
