TL;DR:
Liminal Custody launched a new institutional custody solution called Liminal HSM Vaults, developed in partnership with Securosys, a Swiss company specializing in cybersecurity and encryption. The product combines the company’s patent-pending Multi-Party Computation (MPC) authorization protocol with Securosys’s hardware security modules (HSM), backed by FIPS 140-2 Level 3 certification.
The solution was demonstrated using the Securosys Primus HSM E-Series. According to Boston Consulting Group data cited by the company, assets under management in the institutional digital assets segment could exceed $10 trillion by 2030. Meanwhile, the global HSM market projects a compound annual growth rate of 14.6% through that same year, a trend attributed primarily to financial sector demand for certified cryptographic infrastructure.
Liminal HSM Vaults integrates online and offline devices within the authorization flow, incorporating compliance, security, and custody operations teams directly into transaction processes. The system generates cryptographic proofs that allow the HSM to verify that each authorization is valid, was correctly issued, and aligns with each institution’s internal policy controls. The architecture aims to eliminate single points of failure and guarantee sovereignty over cryptographic keys.
Mahin Gupta, founder and CEO of Liminal Custody, noted that 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, highlighted that the partnership enables banks to “scale digital asset services responsibly” by leveraging the cryptographic trust offered by the Primus infrastructure.
Liminal Custody operates from Singapore, maintains offices in India, the United Arab Emirates, 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 Tier 1 banks worldwide.
