I built an open source Bitcoin AML forensics tool in TypeScript that runs on Android

ChainTrail — Open Source Bitcoin AML Forensics I spent the last few weeks building ChainTrail, a real-time Bitcoin transaction monitoring and AML forensics platform. The interesting part?

Live demo: https://cary-uncompensated-joanie.ngrok-free.dev Key features Live mempool stream via mempool.space WebSocket Transaction graph tracer using PostgreSQL recursive CTEs Interactive D3.js graph visualization 1,258+ threat intel entries (WannaCry, Lazarus Group, Silk Road, OFAC) ML risk scoring 0-100 with feature extraction Address clustering using Union-Find heuristic Pattern detection: layering, smurfing, fan-out, peeling chain Case management with PDF report export Ethereum support with Tornado Cash detection Webhook alerts via Telegram and Discord Tech stack Backend: Node.js + TypeSc
