Rug-check a Solana token before the chart lies to you
One mint address returns the signals a rug pull can't fake: live authorities, a sold-out dev wallet, bundled supply, whale concentration, cloned tickers — each one hard-caps the grade.
A rug pull never announces itself on the chart — the pump looks identical whether the contract is clean or a trap. What a rug can't hide is on-chain: who holds the mint's authorities, whether the dev wallet already sold, how the launch was funded, and how concentrated the supply is. A rug check reads those facts directly and grades them with hard caps, so a pretty candle can't out-score a live freeze authority.
The signals, and what each one means
Every check lands as a hard cap on the safety grade — not a weighted average a strong pump can overwhelm. The caps exist because each of these is, by itself, a reason a token can go to zero:
| Signal | Why it caps the grade |
|---|---|
| Freeze authority live | Your tokens can be frozen — the classic can't-sell honeypot |
| Mint authority live | Supply can inflate — a dilution rug that doesn't need a sell |
| Token-2022 danger extension | Transfer taxes, default-frozen accounts, permanent delegates |
| Dev wallet sold out | The creator exited their own launch — the soft-rug pattern |
| Bundled launch | Insider wallets filled the creation block — coordinated exit risk |
| Whale concentration | Top-10 over 70% on a thin book — one wallet is the market |
| Clone ticker | A known symbol on the wrong mint — impersonation, not the token |
Grades are earned, not assumed
Unverified is not clean — a token whose authorities can't be read caps itself rather than borrowing trust. New launches work under a receipts rule: they climb toward an A only as four facts verify — authorities confirmed, concentration known and bounded, a dev wallet still holding but not dominant, and an organic launch pattern. A pumping chart earns a C at best until those receipts land.
What a rug check is not: a guarantee. It proves what the contract and wallets did, not what the dev plans next — liquidity can still be pulled from a clean-authority token. How liquidity locks work covers that half of the rug surface.

Frequently asked
How do I rug-check a Solana token?
Paste the mint address into the scanner — it reads the token's authorities, dev wallet, launch pattern and holder concentration on-chain, then applies hard caps: live freeze authority, a sold-out dev, bundled supply or a cloned ticker each pin the grade regardless of how the chart looks.
What does a rug check actually detect?
The on-chain signals a rug can't fake: live mint or freeze authority, dangerous Token-2022 extensions, a dev wallet that sold out, insider wallets bundling the creation block, whale concentration on thin liquidity, and tickers cloned off known tokens.
Is the rug checker free?
Yes — paste a mint, get the grade. No signup, no wallet connection, and the same check the scanner runs is what powers the safety caps across the app's token cards.
Does a clean rug check mean the token is safe?
No — it means none of the detectable trap doors are present. Liquidity can still be pulled and devs still sell; treat a clean grade as 'no known trap found', size accordingly.
What if a token can't be verified?
It reads unverified and the grade caps itself — unknown authorities are never treated as clean. A token that can't be positively cleared doesn't get the benefit of the doubt.
