Rug Check Safety Scanner
Paste any SPL token mint and we'll inspect its authorities, metadata and holder distribution on-chain — no wallet signature required.
Enter a token mint above to run a full safety scan: mint & freeze authority, metadata mutability and top-holder concentration.
Solana rug check and token safety scanner
A rug check is the fastest way to gauge the safety of a Solana token before you buy, ape in or add it to a list. This scanner reads a mint's on-chain data — its authorities, metadata and holder distribution — and distills the result into a single safety score out of 100. It is read-only and requires no wallet signature, so scanning is risk-free. Use it to spot the technical red flags behind most rug pulls: tokens whose supply can still be inflated, accounts that can be frozen, mutable metadata, or a handful of wallets sitting on most of the supply.
What the safety checks mean
The most important signals are the mint authority and freeze authority. A revoked mint authority means no one can print additional supply; a revoked freeze authority means no one can freeze your tokens in place. The scan also reports whether the on-chain metadata is immutable (the name and image cannot be swapped later), the token standard, and the supply and decimals. Finally it measures holder concentration — the share of supply held by the top 1 and top 10 accounts — because a tiny number of whales can crash a price instantly. Bear in mind some large accounts are liquidity pools or exchange wallets rather than insiders, so read concentration in context.
How to use it and a safety note
Paste any SPL Token or Token-2022 mint and scan it before interacting — especially before swapping into it or providing liquidity. Treat the score as a screening tool, not a verdict: a clean result means the obvious on-chain risks are absent, but it cannot judge off-chain promises or future team behavior, so always do your own research. Launching your own token? Mint it with revoked authorities using the token creator, then seed a market with the Raydium liquidity tool, and distribute tokens safely with the multisender.

Rug check FAQ
What is a Solana rug check?
A Solana rug check is an automated safety scan of an SPL token that inspects its on-chain properties — mint and freeze authorities, metadata mutability and holder concentration — to flag risks before you buy or interact with it. It reads public on-chain data only and never asks for a wallet signature, so running a scan is completely safe.
What does the scanner check for?
It checks whether the mint authority is revoked (so no new supply can be printed), whether the freeze authority is revoked (so your tokens cannot be frozen), whether the metadata is immutable, the token standard (SPL Token or Token-2022), the total supply and decimals, and how concentrated the top holders are. Each result feeds an overall safety score out of 100.
What is mint and freeze authority?
The mint authority is the address allowed to create new tokens; if it is not revoked, the team can inflate supply at any time. The freeze authority can freeze individual token accounts, blocking holders from moving their tokens. Revoked authorities are generally a positive safety signal, while active authorities mean you are trusting the team not to abuse them.
Why does holder concentration matter?
If a few wallets hold most of the supply, those holders can crash the price by selling — a common rug pattern. The scanner shows the share held by the top 1 and top 10 accounts so you can judge concentration. Keep in mind that some large accounts are liquidity pools or exchange wallets rather than single insiders.
Does a passing scan mean the token is safe?
No. The rug check is an automated on-chain heuristic, not financial advice and not a guarantee. A clean score means the obvious technical red flags are absent, but it cannot detect social engineering, off-chain promises or future team behavior. Always do your own research and never invest more than you can afford to lose.
