The challenge
The custody dilemma has defined digital asset security for years
Cold storage keeps assets safe but slows business down. Hot storage enables speed but exposes assets to hackers. For regulated institutions, such risks are no longer acceptable.
Our solution
Institutional-grade custody without compromise
Custodiex removes the trade-off. Private keys are secured in FIPS-certified Hardware Security Modules (HSMs) within air gapped environments. Keys never leave the hardware unencrypted yet remain available to securely sign transactions in real time.
How it works?
01
Cold Storage Security
Private keys are generated inside certified HSMs in air-gapped environments. Once created, they are wrapped (encrypted) and stored securely outside the HSM, only accessible by being re-imported and unwrapped inside the HSM.
03
Secure Transaction Preparation
When a transaction is requested, a secure process prepares it without ever exposing private keys.
02
Automated Verification
Multiple automated security checks within the cold environment confirm transaction legitimacy without human intervention.
04
Real Time Execution
The transaction is published to the blockchain immediately, while maintaining the full protection of true cold storage.

Why Custodiex?
Certified HSMs in air-gapped environments
Real-time cold storage innovation
Scalable and future-proof architecture
Integration-ready custody layer
Custodiex vs. Online MPC
HSM
Keys generated and used within certified HSMs, never exposed in plaintext
Yes, without exposing private keys
FIPS-certified hardware and NIST-approved algorithms, hardware-based assurance, certifiable
Unlimited vaults and assets
Extremely limited (air-gapped)
Online MPC
Keys split across parties, but remain online
Yes, but online risks remain
Complex to audit
Complex with many parties
Wider, due to online dependencies
This comparison reflects online MPC implementations. Offline MPC can improve security, but does not support real-time availability.
Future-Proof by Design.
Custodiex is built to adapt as standards evolve.
Crypto agile
Supports current cryptographic standards and can adopt new ones as they are approved.
Quantum Safe
Custodiex uses NIST-standardized, quantum-safe cryptography to protect all private keys. Designed to remain adaptable, ready to adopt future algorithms as new standards emerge.
Scalable
Supports an unlimited number of vaults and a wide range of digital assets.
Integration Ready.
Custodiex can operate as a standalone custody layer or connect directly into broader infrastructures. Partners can integrate through standards-based interfaces and build governance or workflows on top of the secure vault foundation.
