Google to launch Multi-Party Compute service for crypto wallets

Google Cloud is reportedly preparing Multi-Party Compute, a service that splits crypto wallet private keys into fragments stored across separate systems. It is in private preview with major financial players, and Alphabet uses it to secure its Ethereum and Solana holdings. General availability is planned for early 2027.

• Keys are split into fragments, some can be kept offline for recovery
• Users can set how many fragments authorize a transaction
• Transaction policy checks run in Confidential Spaces containers
• Alphabet uses the service for its Ethereum and Solana
