Google to Preview MPC-Based Crypto Custody System at New York Summit
Current overview (not historical)
Google will preview its MPC-based crypto custody system at the November New York Digital Asset Summit. The system distributes private key shards across environments and uses a policy engine to check institutional rules before transaction signing, aiming to prevent single-point key leaks and support post-quantum upgrades. Google states the service will commercialize in early 2027 and is currently in private preview with several financial institutions as design partners.

Report first recorded Oct 28, 19:34
Google will unveil a multi-party computation service designed to help financial institutions safeguard and transfer cryptocurrencies and tokenized assets, with commercial availability planned for early 2027. The system distributes private-key fragments across separate environments and applies institutional rules before transactions are signed, reducing the risk that one compromised machine could expose assets. Several major financial institutions are already testing the technology as design partners.
