Cryptoticker Google Launches MPC Service for Institutional Crypto Custody
Article Content

- •Service currently in preview, targeting banks, not retail investors.
On October 28, 2026, Google announced its Multi-Party Compute (MPC) service for institutional custody of cryptocurrencies, primarily targeting banks and large financial institutions. The MPC technology allows multiple parties to jointly authorize and sign transactions without any single entity having access to the complete private key. This method enhances security by splitting the private key into fragments stored in different environments, making it nearly impossible for attackers to exploit a single fragment. The service was previewed during a symposium in New York, attended by major financial institutions. Google Cloud's Confidential Space is utilized to ensure secure computation and policy checks before transaction approvals. The MPC service is currently in preview, with limited support available. Retail investors are not the target audience for this service.
