OPENING
Google Multi-Party Compute (MPC), a security service to help banks and other financial institutions safeguard and move cryptocurrencies and tokenized assets, is in private preview and not yet generally available, with commercial availability planned for early 2027. The service splits a private key into shares held in separate environments and brings MPC-based signing, transaction policies and key recovery into one purpose-built service, so the complete key is never stored in one place.
KEY DETAILS
- Google Multi-Party Compute (MPC), a security service to help banks and other financial institutions safeguard and move cryptocurrencies and tokenized assets, is in private preview and not yet generally available, with commercial availability planned for early 2027.
- The service splits a private key into shares held in separate environments and brings MPC-based signing, transaction policies and key recovery into one purpose-built service, so the complete key is never stored in one place.
- Google is showcasing the service at its digital assets symposium in New York on Wednesday, October 28, 2026.
- Several design partners and financial institutions are testing the technology, and Alphabet has begun using it to secure its own digital assets on Ethereum and Solana; Google has not named the institutions or disclosed pricing.
WHY IT MATTERS
Banks get a Google-built option to hold and move digital assets. (Analysis, not a confirmed fact.)
IMPORTANT CONTEXT
- MPC is an established custody technique: several distinct key shares must work together to authorize a transaction, reducing the risk from a single compromised machine.
- Google previously published guidance for building MPC-based digital-asset systems on its Confidential Space infrastructure, but says it has not offered a dedicated MPC custody product before.
- Google's existing key-protection services include Cloud Key Management Service and Cloud HSM.
