Google Prepares Crypto Custody Service for Banks, With Ethereum and Solana in Focus
Google is preparing to launch a digital asset custody and transaction-signing service designed to help banks and financial institutions secure cryptocurrencies as cyber threats targeting the sector continue to evolve. The service, called Google Multi-Party Compute (MPC), is currently in preview and is expected to become commercially available in early 2027, according to CoinDesk.
The technology is designed to reduce the risks associated with storing and using private keys, which control access to cryptocurrency holdings. Alphabet, Google's parent company, is also reportedly using the technology to protect its own digital assets on the Ethereum and Solana networks.
How Google's Multi-Party Compute Technology Works
Google MPC divides a private key into multiple pieces and distributes them across separate systems rather than keeping the entire key in one location. The approach is intended to make it more difficult for an attacker to gain control of digital assets if an individual device or system is compromised.
Under a potential deployment, a bank could store one portion of a key on Google Cloud, another on its own hardware, and additional portions with a separate cloud provider. The required components would then work together to authorize and sign transactions.
By distributing key components, the system aims to reduce the security risks associated with a single point of failure. Financial institutions handling digital assets could use this approach to separate control of critical credentials across different environments.
Transaction Controls Aim to Limit Unauthorized Transfers
The service is designed to address more than private-key storage. According to the announcement described in the report, Google MPC can also support rules governing how digital assets are transferred, including transaction limits, approved recipient addresses, and multi-factor authentication requirements.
These controls could help financial institutions enforce internal security policies and reduce the likelihood of unauthorized transactions. Combining distributed key management with transaction restrictions provides an additional layer of protection for digital asset operations.
Security Risks Remain Despite Distributed Key Storage
Although distributing private keys can reduce the consequences of a compromised device or system, the approach does not eliminate every threat. Users could still unknowingly approve malicious transactions, meaning operational safeguards and careful transaction verification remain important.
The planned commercial release in early 2027 would give banks and financial institutions another potential option for managing cryptocurrency custody and transaction signing. However, the service's effectiveness will depend on how it is implemented and integrated into each institution's security procedures.
