The Challenge
What the client was facing
The client's existing custody process was largely manual, requiring staff to move funds between hot and cold storage by hand — slow, error-prone, and impossible to scale past a handful of supported assets. As the exchange prepared to list 40+ assets and pursue a new operating license, they needed automated, auditable custody infrastructure that satisfied both security and regulatory reviewers.
The Solution
How Hurain Technologies solved it
Hurain Technologies designed a multi-layer custody architecture combining HSM-backed key management, multi-signature approval workflows, and automated hot/warm/cold rebalancing triggered by real-time liquidity thresholds. We integrated the settlement layer with the exchange's matching engine and built full audit logging for every custody event to support the client's licensing submission.
