GK8 by Galaxy Named Custody Technology Provider for BDACS, Korea’s Leading Regulated Institutional Custodian

BDACS standardizes its institutional platform on GK8’s Impenetrable Vault, uMPC, and policy-driven orchestration

New York / Seoul, September 9, 2025 – GK8, a Galaxy company and institutional digital asset custody platform, today announced that BDACS, a leading regulated institutional digital asset custodian in Korea, has selected GK8 as its custody technology provider to power its institutional digital asset offering.

Through GK8’s category-defining Impenetrable Custody architecture – featuring its Impenetrable Vault, uMPC (Unlimited Multi-Party Computation), and Policy-Engine that enables the platform to be tailored to meet regulatory requirements of each jurisdiction – BDACS will deliver secure, compliant, and scalable custody services to Korean institutions. The platform will also integrate with Galaxy’s validator infrastructure to enable institutional staking, while also leveraging GK8’s Tokenization Wizard for the issuance and management of tokenized assets, including stablecoins and money market fund tokens.

This collaboration extends Galaxy’s growing footprint in Korea. Together with BDACS, Galaxy is developing a full suite of institutional services – including custody, staking, lending, and risk management – while building ETF infrastructure and liquidity through Galaxy’s global network. The partnership, announced earlier this year, is expected to gain momentum as the regulatory landscape in Korea continues to evolve.

“Institutions in Korea are demanding custody technology that is both secure and built for scale,” said Lior Lamesh, Co-Founder & CEO at GK8 by Galaxy. “By choosing GK8, BDACS is giving its clients the strongest possible foundation – combining ironclad security with institutional-quality governance and full regulatory alignment.”

“Our mission is to set the standard for institutional digital asset infrastructure in Korea,” said Harry Ryoo, CEO at BDACS. “With GK8’s custody technology, we can deliver the security, policy control, and operational efficiency our clients expect – while expanding access to institutional prime services like staking through Galaxy through battle-tested infrastructure.”
