Google crypto security preview

Highlights

Google will preview a crypto security service using MPC technology at its digital assets symposium, with major financial institutions and Alphabet itself testing the system on Ethereum and Solana.
Chainalysis data shows 43.8% of cryptocurrency stolen in 2024 involves compromised private keys, with blockchain hack losses totaling $16.69 billion as of June, underscoring institutional demand for key protection.
Recent AI-enabled crypto scams average $3.2 million per operation in 2025, much higher than $719,000 for non-AI scams, amplifying institutional cybersecurity concerns.

Product rollout and security design

As first reported by CoinDesk, Google is set to showcase the service at its inaugural digital assets symposium in New York City on Wednesday. Several design partners and major financial institutions are testing the technology, while Alphabet is already using it to secure some of its own digital assets on the Ethereum and Solana blockchains.

The system splits private-key fragments across separate environments and applies institutional rules before transactions are signed. Google says this reduces the risk that a single compromised machine could expose assets, while customers retain control of their key material and the company cannot access it in unencrypted form, even when key shares are stored on Google's infrastructure.

Google has not identified the financial institutions involved in testing, disclosed which digital assets Alphabet is protecting, or set out pricing for the service. The company says it has not previously offered a dedicated MPC custody product for cryptocurrencies, although its existing production offerings include Google Cloud Key Management Service and Cloud HSM for cryptographic key protection.

Rising hack losses shape institutional demand

Private-key security remains a central challenge for institutions entering digital assets because anyone who gains control of a wallet's key may be able to move funds without authorization. Google says the service is built to address compromised credentials and unauthorized transactions, and it adds that the platform can eventually support post-quantum cryptography.

The market backdrop highlights the scale of the threat. Chainalysis says compromised private keys account for 43.8% of cryptocurrency stolen in 2024, while DeFiLlama data shows blockchain projects have lost a cumulative $16.69 billion to hacks and exploits as of June this year, with roughly 40% tied to private-key compromises.

Google is also framing the launch against more sophisticated cyber risks involving AI and quantum computing. Chainalysis says crypto scams linked to AI-tool vendors extract an average of $3.2 million per operation in 2025, versus $719,000 for scams without such links, while recent attacks including a March breach at Resolv and a June incident affecting Humanity Protocol underscore the operational risks facing institutional digital-asset platforms.

In our earlier coverage of the surge in global cybersecurity funding, we highlighted how capital flowed into fewer but much larger late-stage rounds, lifting total investment even as deal counts declined. We also noted that AI-driven and identity-security firms attracted the most attention, alongside accelerated consolidation through major acquisitions—signaling that enterprise security concerns were intensifying and shaping spending priorities.
