Low-latency cross-platform arbitrage written in Rust.
Watches 10,000+ Polymarket and Kalshi markets for mispriced pairs.
Paper-only Python scanner that watches live Polymarket order books for moments when the YES and NO asks plus fees add up to less than $1, checks that the depth is real, and simulates the fills. Has one engine for BTC 5-minute windows and one for the wider active market set, with Streamlit and FastAPI dashboards. Any edge it reports is simulated, not verified.
