How Risk Scoring Works

Each contract is scored independently. The overall score is the highest individual contract score. Scores are additive — multiple risk factors compound.

Risk Levels

Low RiskScore 0–20Verified, well-known, no red flags
CautionScore 21–40Minor concerns — review flags
WarningScore 41–70Significant risk factors detected
DangerScore 71+Multiple high-risk factors

Scoring Factors

⚠ This is automated heuristic analysis, not a security audit. Scores can be wrong — a low score does not guarantee safety, and a high score does not guarantee malice. Always do your own research.
