Read the chain directly. Then act on what it says.
Wallet and token checks on Solana & Robinhood Chain: paste an address, and there is no wallet to connect and nothing to sign. When a check finds something worth fixing, the operation that fixes it is one click away — and your own wallet signs it.
Every tool here started as something found by reading the chain directly, and the research that found it is published in full.
Proof
Each tool started as a question
The research is not marketing for the tools. It is where they came from — someone read the chain, found something the documentation did not mention, and then built the thing that acts on it.

The tools
What you can check, and what you can fix
The checks are read-only: paste an address, and they read public chain data — no wallet connection, nothing to sign. A check is a read, not a promise. It reports what the chain says right now, and plenty of wallets come back clean.
Solana
Eleven read-only checks, then the operations to act on them.
- Check a wallet
- Audit a token
- Reclaim SOL from empty accounts
- Take back the rent surplus
- Unwrap wrapped SOL
- Revoke mint and freeze authority
- Create a token
Robinhood Chain
Chain 4663 — read directly, since the docs leave a lot out.

How to Claim SOL From Empty Solana Token Accounts
Every empty token account still holds the ~0.002 SOL deposit it was opened with, and nothing on the network closes it for you. What "claim SOL" really means, how the deposits stack up, what the SIMD-0437 rent cut leaves behind, and the exact close-and-refund flow — tool, CLI, or wallet.
Solana's 4,096-Byte Transactions: What v1 Breaks and How to Fix It
SIMD-0296 raises the transaction limit from 1,232 to 4,096 bytes via a new v1 wire format — and the day the gate activates, un-upgraded readers start failing with error -32015. What changes, what breaks silently, and the exact fix for each symptom.
