Overview

PAX delivers more 𝛼 with its in-silicon exchange and HFT technology. The PAX on-chip λ API provides deterministic nanosecond tick-to-trade latency. HFT λ traders experience non-adverse counterparty selection by pairing with free-tier traders who access PAX using our zero-cost and rebated API.

Using our patented technology, PAX is building a new generation of exchange co-lo facilities that unite HFT with exchange.
