Blockchain.com has launched an institutional trading API that gives clients direct electronic access to its principal liquidity across major cryptoassets, altcoins and stablecoins. The company announced the service on 5 November as an extension of its existing prime brokerage offering.[1]
Clients can obtain all-in executable quotes and trade directly with Blockchain.com through the interface. That describes a principal dealing relationship: the client trades against the provider’s liquidity, rather than using the API as a neutral router to several competing exchanges.[1]
The service operates around the clock and complements the company’s voice and chat OTC desk. Eligible clients can trade without prefunding and select settlement schedules suited to their operations. Eligibility is material: those terms are not an unconditional credit facility for every applicant.[1]
Electronic access expands an existing relationship
Blockchain.com says its institutional prime brokerage business serves more than 1,500 clients. That total covers the wider business, including existing services; the announcement does not say 1,500 institutions have adopted the new API.[1]
The launch gives institutional dealing systems another way to request prices and execute with an existing counterparty. It does not publish a fee schedule, a guaranteed spread or a latency benchmark. The commercial effect will depend on executable pricing and the settlement terms agreed with each client, while automated trading remains an additional channel alongside the OTC desk.[1]
