Depth Metrics

The mathematical risk scoring formula and programmatic API integration behind depth measurement.

Mathematical Weight Formulation
Total Risk Depth = (Static × 0.4) + (Behavioral × 0.3) + (Payment × 0.2) + (Sybil × 0.1)
Static Risk (40%)
EVM Bytecode & SWC Vulnerabilities
Behavioral Risk (30%)
Transfer Graph & Rhythm Density
Payment Risk (20%)
x402 Economic Receipt Authenticity
Sybil Risk (10%)
Louvain Multi-Cluster Community
Developer API & SDK Integration
