A Python library that detects cryptocurrency arbitrage opportunities across 120+ exchanges in ~50 countries using graph algorithms like Bellman-Ford, built on top of ccxt. Created as a 2017 proof-of-concept and no longer maintained.

Use cases

  • find crypto arbitrage opportunities across exchanges
  • detect price differences for one trading pair on multiple exchanges
  • find profitable trading cycles on a single exchange
  • scan exchanges by country for arbitrage
  • build a crypto arbitrage bot in python

When to choose

  • you want a ready-made arbitrage detection algorithm over ccxt-supported exchanges
  • you need Bellman-Ford negative-cycle detection for trading graphs
  • you're learning how crypto arbitrage works

When to avoid

  • you need maintained, production-ready trading software
  • you require up-to-date exchange API compatibility
  • you want guaranteed execution or order placement - it only detects opportunities
