Google Cloud outlines MPC service for institutional Bitcoin custody
Summary
Google Cloud is developing a preview MPC service for institutional Bitcoin custody, allowing multiple parties to authorize and sign transactions without any one party holding the complete private key. Updated documentation describes rules that can assess transaction amounts, destination address types and change outputs. The update came ahead of a Google Cloud MPC event featuring speakers from major financial institutions. Google’s release notes date the service to August 2026; its launch timeline and availability remain unclear.
