Crossover Markets operates CROSSx, an execution‑only digital‑asset electronic communication network (ECN) that provides institutions with ultra‑low‑latency trade execution and custom dark and lit liquidity pools. The platform does not offer custody or brokerage services and connects participants via FIX API or a GUI, trading 24/7 with sub‑20 µs matching engine latency. Fees start at 0.01% and decrease with volume, with commissions waived for certain stablecoin pairs.
