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 Created as a 2017 proof-of-concept and no longer maintained.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
