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.

Solana WebSockets That Stay Connected but Miss Updates
Measured on mainnet on 5 November 2026: a finalized logsSubscribe stream on Agave 4.4 never scanned 3% of slots and missed one finalized transaction in thirty, with no error and no disconnect. Why programSubscribe and logsSubscribe read one slot per update, why confirmed is better but not complete, the open fix, and the reconciliation loop that catches the gap.
Two Tokens, One Stock: The Weekend Arbitrage Nobody Ran
Eleven Uniswap v4 pools on Robinhood Chain swap Ondo and Robinhood tokens for the same stock at a stored rate. Read from the chain for their first week: one account set them up and can change the rate, they carried 0.05% of the tokens’ trading, and on the first weekend no Ondo token was bridged in or out.
When a Solana Feature Activates but Its Program Migration Fails
SIMD-0690 makes the runtime hash a replacement program before swapping it in. Replayed on the real p-ATA buffer from mainnet: the hash matches, every failure leaves the gate active and the Associated Token Account program unchanged, and if the gates activate out of order Agave and Firedancer deploy different bytes.
