Susanoh is an AI-powered RegTech middleware designed to protect game economies from Real Money Trading (RMT) and money laundering without the risk of "false positive" bans. By adding a single API endpoint, developers deploy a Two-Tier Honeypot Architecture that isolates illicit funds while keeping innocent players safe. First, L1 High-Speed Screening flags anomalies in real-time. Flagged accounts enter a RESTRICTED_WITHDRAWAL state, where they can still deposit funds—creating a honeypot effect—but receive a 423 Locked error upon withdrawal. Next, L2 Deep Context Analysis via Google Gemini evaluates chat and trade history to provide a risk_score and clear reasoning. With D3.js visualizations to expose "Smurfing" networks and a stack featuring FastAPI and React, Susanoh ensures an explainable, secure, and developer-friendly defense system.
