GK8

GK8, a subsidiary of Galaxy Digital (TSX:GLXY), operates as a cybersecurity firm specializing in high-security custodian technology for digital assets. The company was established in Tel Aviv, Israel, in July 2018 by Lior Lamesh (CEO) and Shahar Shamai (CTO). Both founders cultivated their expertise in cybersecurity within elite units of the Israeli Prime Minister's Office, where they were tasked with protecting the nation's strategic assets. Their decision to start GK8 stemmed from identifying significant security vulnerabilities in the digital asset market after successfully hacking a popular crypto wallet. The company targets institutional clients such as banks, hedge funds, exchanges, and other financial institutions, providing them with an on-premise, end-to-end platform for managing and safeguarding digital assets.

The company's journey includes a seed funding round of $4 million and a Series A round that brought its total funding to over $10 million. In November 2021, the crypto lender Celsius acquired GK8 for $115 million. Following Celsius's bankruptcy filing, Galaxy Digital acquired GK8 in February 2023 for approximately $44 million, integrating its team and technology. Lamesh and Shamai continue to lead Galaxy's custodial technologies business, and the acquisition added a Tel Aviv office and nearly 40 employees, including cryptographers and blockchain engineers, to Galaxy's operations.

GK8's core offerings are its patented "Impenetrable Vault," a cold storage solution, and a proprietary multi-party computation (MPC) vault, which it refers to as uMPC. The Impenetrable Vault's main feature is its ability to create, sign, and send blockchain transactions without any internet connectivity, utilizing a unidirectional outbound connection. This air-gapped design is intended to eliminate cyberattack vectors. The MPC vault facilitates automated, high-frequency transactions by splitting private key shares among multiple parties. Together, these products offer a hybrid solution for both secure offline storage and operational flexibility for activities like DeFi, staking, and tokenization. In April 2024, GK8 launched a "Tokenization Wizard," a user-friendly interface for creating and managing tokenized real-world assets on various blockchains. The company's business model is based on providing these custody technology solutions to financial institutions, which will also be integrated into Galaxy's own prime brokerage platform, GalaxyOne.
