Swap WETH from Arbitrum One to SOL on Solana

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

Sell 0x82aF49447D8a07e3bd95BD0d56f35241523fBab1. Arbiscan, chain id 42161, not Nova. Keep native ETH for gas. The mint is So11111111111111111111111111111111111111112. Solscan and Phantom. Wrapped SOL is not an ERC-20, so there is no destination approval. A 0x recipient fails. Slots near 400 milliseconds are not a promise. Unwrapping WETH on Arbitrum does not mint this.

WETH withdraw is not a bridge to So111

Calling withdraw on 0x82aF49447D8a07e3bd95BD0d56f35241523fBab1 returns ETH on Arbitrum One. You stay on chain id 42161. This route can credit the wrapped SOL mint instead. That mint is not native lamports until Phantom unwraps it. It is not Ethereum WETH and not the EVM sentinel. Solscan is the only explorer that should show the credit.

Two wrapped assets, two fee coins

You sell an ERC-20 and you may receive an SPL mint that wallets label SOL. Fees on the source are still ETH. Fees on the destination are native SOL, which may require an unwrap if you only hold So111. Do not spend the last ETH on Arbitrum while trying to create SOL. Solana will not accept the Arbitrum WETH address as a mint.

Price, not a wrap ratio

One WETH does not redeem for one SOL. The minimum expires. Decimals differ. Read the quote in whole units. If you unwrap WETH first, this page's input disappears and you should switch to the native ETH route, still reserving gas.

Wrong if a stable mint was the point

Circle USDC and Tether USDT on Solana are other pages. Native ETH holders are the wrong input. Nova is the wrong source. An EVM exchange deposit is the wrong recipient. Watching Arbiscan for So111 will show you nothing useful. Before you sign, compare 0x82aF49447D8a07e3bd95BD0d56f35241523fBab1 with So11111111111111111111111111111111111111112 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. Gas on the source chain is separate from the asset you hope to receive.

Frequently asked questions

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

Sell 0x82aF49447D8a07e3bd95BD0d56f35241523fBab1. Arbiscan, chain id 42161, not Nova. XAUConnect compares live routes and lets your own wallet sign.

Does unwrapping Arbitrum WETH give me SOL?

No. Withdraw on 0x82aF49447D8a07e3bd95BD0d56f35241523fBab1 pays ETH on chain id 42161. This route can credit So11111111111111111111111111111111111111112 in Phantom. That is wrapped SOL, seen on Solscan, not an ERC-20. There is no approve call on Solana. Native lamports are what pay fees after an unwrap. Confirm the address on the explorer before you sign.

Can I send So111 to my Arbitrum address?

No. The recipient has to be a Solana address in Phantom or a similar wallet. A 0x string cannot hold the mint. Arbiscan is only for the WETH you sell. A slot near 400 milliseconds does not make the address formats compatible. Confirm the address on the explorer before you sign.

What must sit beside WETH before I start?

Native ETH for gas, sentinel 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE, on chain id 42161, not Nova. WETH cannot pay the fee. The SOL you want cannot pay it either. Leave a cushion, then watch Phantom for the wrapped mint. Confirm that address on the explorer before you sign, and refresh the quote if it has expired.
