Google Cloud Builds Institutional Crypto Custody with MPC Key Splitting
- —MPC distributes key shares so the full private key is never assembled in one place
- —Institutions can set transaction limits, destination restrictions and approval thresholds
- —Currently in private preview, with commercial launch targeted for early 2027
- —Alphabet already uses the service to secure assets on Ethereum and Solana
Why it matters: Google enters institutional custody, competing with Fireblocks, BitGo and Fordefi as banks expand into digital assets and key compromises drive crypto theft.
