The zerohash platform supports three core pillars: Trade, Transact, and Tokenize. Through a single integration, customers can launch regulated crypto buy, sell, and custody services; enable 24/7 stablecoin-based funding, payouts, and settlement; and issue and manage tokenized assets with built-in compliance, risk controls, and reporting.
