# Ethereum Fraud Detection System
This Space demonstrates a **Graph Neural Network (GraphSAGE)** model designed to detect illicit activities on the Ethereum blockchain.
## 🧠 Model Overview
The model operates on an inductive basis, meaning it learns to aggregate information from a node's local neighborhood (transactions in/out) to generate embeddings and predict the likelihood of fraud.
* **Architecture:** GraphSAGE (Graph Sample and Aggregate).
* **Input Features:** Transaction volume, degree (in/out), time-based features, and graph properties (PageRank, etc.).
* **Output:** A probability score (0-1) indicating the likelihood of the address being involved in criminal activity (Phishing, Hack, Scam).
## 📊 How to use
1. Enter an Ethereum address (must be present in the analyzed snapshot dataset).
2. The system looks up the pre-calculated risk score from the model inference.
3. It visualizes the **Ego Graph** (1-hop neighborhood) to show who this wallet interacts with.
