Core Features of Our Reputation Engine
Our reputation engine provides a multi-dimensional risk assessment layer for on-chain activity, enabling FinTechs and Web3 platforms to automate compliance, reduce fraud, and build trust at scale.
01
Multi-Dimensional Risk Scoring
Analyze wallet behavior across 50+ on-chain dimensions including transaction patterns, DeFi interactions, NFT history, and counterparty exposure. We deliver a single, interpretable risk score (0-1000) for real-time decisioning.
