SOL.repair

Reclaim SOL from empty token accounts.

If you have used Solana for a while, you have probably racked up a bunch of old token accounts from airdrops, swaps, and spam tokens. Every one of them holds about 0.00186 to 0.00204 SOL as rent, depending on when the account was created, and you can't spend it until the account gets closed.

This site finds those accounts in your wallet, shows you exactly how much you can get back, and closes them in one or a few quick transactions that you approve in your own wallet.

What it is

A non-custodial web app. That means:

• It never touches your private keys or seed phrase.
• It never holds your funds.
• It builds a transaction and your wallet shows you what it does. You sign it or you don't. Nothing happens without your approval.
• The transaction closes your empty token accounts and sends the rent straight back to your own wallet.
• There is a 1% success fee on what you recover. It is a transfer to the published fee address inside the same transaction, visible in your wallet before you approve. It pays for keeping this thing running.

The code that builds the transaction is right here. Read it. If you don't trust it, don't use it.

What it is not

• Not a swap tool. It doesn't trade your tokens for anything.
• Not a custody service. It never has your money, so there is nothing to run off with.
• Not financial advice. It's a utility that runs one specific on-chain operation and nothing else.

The fee ledger

The site has a public fee ledger at /fees. It lists every fee transfer into the fee wallet, straight from chain data, with the amount, the transaction signature, and the date. Every row links to the transaction on Solscan, so you can verify any of it yourself. Mainnet and devnet are listed separately, and test transactions are labeled as tests.

The page is display only. It reads the chain in your browser and it never changes anything. It does not show the wallet addresses behind the fees, just the amounts and the signatures. An automated audit re-checks the rule against the chain every six hours, so a fee that does not conform gets caught by more than one pair of eyes.

What gets closed

Token accounts (classic SPL Token and Token-2022) that pass all of these:

1. Zero token balance. If an account holds any tokens at all, it gets left alone. The app enforces this and so does the Solana program, so it's checked twice.
2. Not actively delegated.
3. Close authority still with your wallet. Some accounts created by other programs can only be closed by those programs, so they are skipped.
4. Not wrapped SOL.
5. In the "initialized" state.

Fail any one of those and the account is skipped, no exceptions. NFTs and any account holding tokens are protected by the zero-balance rule.

Running it locally

Node.js 20 or newer.

npm install
npm run dev

Then open http://localhost:3000.

The app defaults to Solana devnet and the UI shows DEVNET right on it so you can't mistake it for mainnet. Mainnet is an explicit config change, not the default.

The network and RPC endpoint are set with environment variables. Copy .env.example to .env.local and edit what you need. The example file explains each variable. The short version is that NEXT_PUBLIC_SOLANA_NETWORK picks the network and NEXT_PUBLIC_MAINNET_RPC_ENDPOINT optionally points mainnet at a dedicated RPC provider instead of the public endpoint.

Tests

npm test

The suite covers the account eligibility rules, transaction building, fee math, and the repair flow. It runs against local fixtures, never the live chain, so it is safe to run anywhere.

Tech stack

Next.js (App Router), TypeScript, Tailwind CSS, @solana/web3.js v1, and the @solana/wallet-adapter-react suite.

Why web3.js v1 instead of v2: v2 is Anza's current recommendation, but the wallet adapter libraries haven't fully caught up to it yet (see the open compatibility issues). Wallet compatibility is part of the security of this app, so v1 is the lower-risk choice right now. The Solana-specific code is isolated under src/lib/solana/, so moving to v2 later won't mean a rewrite.

Security model

• Non-custodial. The app never has access to your private keys.
• Transactions are built in the browser and signed in your wallet. The app can't sign on your behalf.
• Wallet addresses are never read from URLs or query parameters. Only the connected wallet's public key is used.
• Recovered SOL always goes back to the connected wallet.

Status

Live at https://sol.repair on Solana mainnet. There is a 1% success fee on recovered SOL, taken as a transfer inside the repair transaction, so it is always visible in your wallet before you approve. Details in the Terms of Service on the site.
