Solana Wash Trades Detector

This project fetches on-chain Solana DEX trades data from Bitquery, labels potential wash-trades based on a set of defined rules, trains an XGBoost model, and deploys an interactive Streamlit dashboard to visualize suspicious trades and compute risk metrics.

How It Works​

  1. Data Collection: Live Solana DEX trades are fetched from Bitquery using GraphQL APIs.
  2. Trade Labeling: A set of defined rules (e.g., self-trading, repeated trading loops, price spoofing) is applied to label trades as potentially suspicious (wash trades).
  3. Model Training: A machine learning model (XGBoost) is trained on the labeled data to learn patterns indicative of wash trading.
  4. Visualization: A clean and interactive dashboard built with Streamlit displays incoming trades, volume metrics, risk concentration, and predicted suspicious activity in real time.
