# Google to preview crypto custody security system as AI threats grow

> Google’s Multi-Party Compute service enters private preview to help banks safeguard crypto assets amid rising AI and quantum threats.

## Key Takeaways (TL;DR)

- Google Multi-Party Compute (MPC) is in private preview with several major financial institutions testing it.
- The system splits private-key fragments across environments and enforces transaction policies before signing.
- Commercial availability is planned for early 2027, with future support for post-quantum cryptography.

Google announced a private-preview security service called Google Multi-Party Compute (MPC) at its inaugural digital assets symposium in New York, targeting banks and other financial institutions that handle cryptocurrencies and tokenized assets[CoinDesk](https://www.coindesk.com/tech/2026/10/28/google-to-preview-crypto-custody-security-system-as-ai-threats-grow)(https://www.coindesk.com/tech/2026/10/28/google-to-preview-crypto-custody-security-system-as-ai-threats-grow). The system distributes private-key fragments across separate environments, applies institutional rules, and only signs transactions when policy checks are satisfied, reducing the risk that a single compromised machine can expose assets. Alphabet, Google’s parent company, has begun using MPC to secure its own digital assets on the Ethereum and Solana blockchains, while several unnamed design partners are testing the technology. Google plans to make MPC commercially available in early 2027 and says the architecture can later accommodate post-quantum cryptography, though current protections focus on compromised credentials and unauthorized transfers.

Our read: Google’s entry leverages its cloud infrastructure to offer a purpose-built MPC custody product, shifting the burden of assembling multi-party signing, policy enforcement, and key-recovery from banks to a single provider. By keeping key shares distributed and never storing the full key in one location, the service directly addresses the dominant attack vector—private-key compromise—while positioning itself for future quantum-resistant upgrades.
