The technology also incorporates institutional transaction controls designed to help prevent unauthorized transfers. While the internal workings of the product are yet to be disclosed, Google faces stiff competition from industry first movers offering institutional custodial services, including Fordefi, BitGo and Fireblocks.
“Digital asset adoption and tokenization are at an inflection point,” said Rich Widmann, director of digital assets strategy at Google Cloud. “As regulated financial institutions begin adopting blockchains and tokenization, they need scalable, proven infrastructure to secure their clients’ assets.”
Several financial institutions are reportedly testing the service, although Google has not disclosed their identities. Alphabet, Google's parent company, has also begun using the technology to secure its own digital assets on Ethereum and Solana. According to industry sources, Google is eyeing an official rollout in early 2027.
Quantum computing remains a longer-term concern
Google's announcement comes as cryptocurrency companies face growing pressure to address vulnerabilities in the cryptographic systems that secure digital assets.
In March 2026, Google Quantum AI researchers warned that future quantum computers could break elliptic-curve cryptography, which underpins critical security mechanisms across much of the cryptocurrency industry.
The researchers estimated that certain quantum computing systems could eventually attack this cryptography using substantially fewer resources than previously estimated. Google has urged the industry to prepare for post-quantum cryptography, setting a 2029 timeline for its own transition efforts.
Google's new MPC service could eventually support post-quantum cryptography. However, its current focus is protecting against compromised credentials and unauthorized transactions, rather than directly eliminating quantum-computing vulnerabilities.
Google's entry comes on the heels of a laundry list of hacks and security breaches that have rocked the digital asset landscape. Since the start of the year, 230 crypto protocols have suffered hacks, putting 2026 on course to be the worst year on record for the industry.
