Liminal Custody, in partnership with Swiss cybersecurity firm Securosys, has officially launched a new institutional-grade digital asset custody solution called Liminal HSM Vaults. The product integrates Multi-Party Computation (MPC) authorization protocols with certified Hardware Security Modules (HSMs) to create a layered security architecture aimed at banks, custodians, and large enterprises entering the digital asset space.
The solution was demonstrated using Securosys's Primus HSM E-Series, which holds FIPS 140-2 Level 3 certification. The architecture is designed to eliminate single points of failure by distributing transaction authorization across multiple participants while keeping the underlying cryptographic keys secured within the tamper-resistant hardware. The system integrates both online and offline devices into the authorization workflow, allowing compliance, security, and operations teams to be directly involved. It generates cryptographic proofs to verify that each authorization is valid and aligns with an institution's internal policy controls before execution.
The launch addresses a growing institutional demand for custody solutions that meet traditional finance's governance and compliance standards. Citing data from Boston Consulting Group, Liminal notes that assets under management in the institutional digital assets segment could exceed $10 trillion by 2030. Concurrently, the global HSM market is projected to grow at a compound annual growth rate of 14.6% through 2030, driven largely by financial sector demand.
Mahin Gupta, founder and CEO of Liminal Custody, stated the solution combines "the static security of HSM with the distributed security of MPC to deliver a product that stands apart from the rest." Robert Rogenmoser, CEO of Securosys, emphasized that the partnership enables banks to "scale digital asset services responsibly" by leveraging the cryptographic trust of the Primus infrastructure. Liminal Custody is based in Singapore with offices in India, the UAE, and Taiwan, and holds ISO 27001, ISO 27701, and SOC Type 2 certifications. Securosys, headquartered in Zurich, provides HSM solutions to more than half of the world's Tier 1 banks.
