A heterogeneous Graph Attention Network trained on the Elliptic++ Bitcoin transaction graph — 203K transactions and 822K wallet addresses — served live from Neo4j and an MLflow model registry. Every number on this site is a real query against a running graph database and a real model, not a static demo.
Elliptic++ CSVs loaded into a heterogeneous Neo4j graph of Transaction and Wallet nodes.
A 2-layer HeteroGAT beats a logistic-regression baseline on test PR-AUC, tracked and registered in MLflow.
FastAPI fetches a transaction's real Neo4j neighbourhood and scores it with the registry's champion model, live.
