RugCheck is a token security scanner built for the Solana ecosystem. It analyses a token's on-chain properties: including mint authority status, freeze authority, LP lock status, holder concentration, and token extension risk flags: and produces a risk score.

RugCheck is used by investors to quickly assess whether a token has obvious red flags before purchasing. A token with revoked mint and freeze authority, locked LP, and no suspicious extensions scores better than one where the creator retains all privileges.

RugCheck integrations are commonly displayed in token analytics platforms and trading interfaces as a quick-reference safety score. The platform also provides detailed breakdowns of each risk factor.
