Swap ETH from Base to SOL on Solana

Swap ETH from Base to SOL on Solana. Native ETH leaves Base, and SOL arrives as the wrapped SOL mint on Solana.

You sell Base ETH, chain 8453, the gas coin marked 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE. Basescan shows the account. Leave a fee remainder. There is no ERC-20 approval on that coin. The destination mint is So11111111111111111111111111111111111111112, the wrapped SOL mint routes use for SOL. Solscan shows it. It is not an ERC-20 on Base. Phantom holds it. MetaMask does not. Native SOL pays Solana fees. Solana has no ERC-20 approval.

The mint that stands in for SOL

So11111111111111111111111111111111111111112 is the canonical wrapped SOL mint, not a novelty ticker. Quotes use it when the asset you buy is SOL. Wallets often show that balance as SOL. Native SOL is still what pays fees, and a quote for the mint is not a promise that spare fee SOL remains after you arrive. If you wanted a 0x token named SOL on Base, this page is the wrong network.

You are spending Base gas

ETH pays the send and is the asset sold. A full balance can fail. WETH at 0x4200000000000000000000000000000000000006 is not accepted. You do not receive ETH on Solana. You receive the wrapped SOL mint in a Solana wallet. Trade on Solana is that receiving side. No duration is promised.

What to refuse

Refuse the quote if you needed a stablecoin. Refuse it if you only needed to keep ETH on Base. Refuse it if the minimum SOL is too small. Basescan records ETH leaving. Solscan records the wrapped SOL mint. Those hashes are not the same object.

Frequently asked questions

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

You sell Base ETH, chain 8453, the gas coin marked 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE. Basescan shows the account.

Is So111 an ERC-20 I hold in MetaMask?

No. So11111111111111111111111111111111111111112 is the wrapped SOL mint on Solana. The asset you sell is native ETH on Base, 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE, chain 8453. MetaMask cannot store the mint. Use Phantom and confirm it on Solscan. Solana does not use ERC-20 approvals. Native SOL pays fees and is separate from the mint.

Does this include extra SOL for fees?

The mint is how the route represents SOL, and native SOL pays Solana fees. The quote's minimum is the amount, not a fee reserve. You still need leftover ETH on Base to broadcast the send. Have a Solana wallet ready before you sign, or the credit has nowhere to land.

I wanted USDC on Solana, not SOL. Is this it?

No. Circle's Solana USDC is EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v. Tether is Es9vMFrzaCERmJfrF4H2FYD4KCoNkY11McCe8BenwNYB. This page delivers the wrapped SOL mint. If the order is a dollar, leave it. SOL will not satisfy a stablecoin payment. Pick the Circle or Tether mint if the invoice names a dollar on Solana.
