Evidence reviewed
Regulation / role

GK8 was acquired by Galaxy after the transaction announced in 2022 and completed in February 2023. Galaxy now refers to its Custody Infrastructure platform as formerly known as GK8.

Security assurance

Galaxy/GK8 documents Cold Vault technology that enables transaction signing without internet connectivity and MPC controls for operational flexibility.

Asset protection

The technology can support institutional custody or self-custody architectures, but the legal custodian and asset-segregation framework depend on the deploying institution.

Institutional services

GK8 technology, now presented within Galaxy Custody Infrastructure, combines always-offline Cold Vault architecture with MPC and institutional digital-asset operations tooling.

Procurement caveat: Corrected legacy context: Galaxy announced the acquisition in December 2022 and completed it in February 2023. Current Galaxy materials describe the platform as Galaxy Custody Infrastructure, formerly known as GK8.

Custody ecosystem — self-custody / wallet infrastructure

GK8 is retained because its technology is relevant to institutional custody architecture, but it is not classified here as the legal third-party custodian. GK8 supplies institutional custody/self-custody technology and key-management infrastructure; it should not be presented as the regulated legal custodian by default.
