Blockchain.com has formally launched an API-powered trading service for institutional clients, expanding its prime brokerage capabilities with automated 24/7 access to its principal crypto liquidity. Announced in London on November 5, 2026, the new offering is designed for hedge funds, family offices, corporate treasuries, and quantitative asset managers that want direct electronic execution without relying solely on manual OTC channels.
The API gives eligible institutions access to all-in executable quotes, transparent pricing, and direct execution with Blockchain.com. A key feature is that qualifying clients can trade without pre-funding, with settlement schedules that can be aligned to their internal treasury cycles. The system runs continuously seven days a week and is compatible with order management systems and existing execution platforms, reducing operational complexity.
Marc Sischka, Global Head of OTC Trading at Blockchain.com, said institutions want direct, seamless access to deep liquidity and execution capabilities, and the API gives them greater control while maintaining personalized service. The automated channel does not replace Blockchain.com’s voice and chat OTC desk; it operates in parallel for complex or illiquid block trades.
Blockchain.com serves more than 1,500 institutional clients and provides OTC spot and derivatives trading, custody, staking, and yield generation. Since 2011, it has supported over 95 million wallets, 44 million confirmed accounts, and more than $1.1 trillion in crypto transactions across more than 70 jurisdictions.
