PERSONAL HSM
FOR SOVEREIGN
SELF-CUSTODY
A personal Hardware Security Module (HSM) is the natural evolution of self-custody.
A portable encryption and signing device designed for both individuals and enterprises, enabling the secure protection of cryptographic secrets without reliance on servers, third-party software, or centralized infrastructures.
​
Cuvex is the first device designed specifically as a personal HSM for sovereign self-custody, focused on securing seed phrases and enabling deliberate, user-verified transaction signing.
WHAT IS AN HSM AND WHY IT MATTERS
Traditional HSMs are devices used by banks, payment processors, and large enterprises to:
​
-
Generate cryptographic keys
-
Encrypt sensitive information
-
Sign critical operations
-
Prevent the extraction of secrets, even under physical attack
​
Until now, this technology has been reserved for corporate environments.
​
Cuvex brings this model to the individual, removing intermediaries and returning cryptographic control to the end user.
WHAT MAKES CUVEX A PERSONAL HSM
Cuvex acts as a personal HSM because it:
-
Encrypts secrets at the hardware level, not in software
-
Never exposes private keys to connected systems
-
Automatically wipes memory after each operation
-
Separates secret generation, storage, and usage
The result is a device that does not custody funds, but instead cryptographically authorizes actions under explicit human control.
WHAT CUVEX IS NOT
It is not custody
It is not a backend.
It is not a server-connected suite.
It is not a wallet that audits balances.
Cuvex does not observe your activity. It only signs when you choose to sign.
WHY A PERSONAL HSM IS SUPERIOR TO A TRADITIONAL HARDWARE WALLET
Traditional hardware wallets prioritize user experience through connected applications, automatic synchronization, and integrated services.
​
This introduces:
​
-
Third-party dependencies
-
Data correlation
-
Additional attack surfaces
​
A personal HSM eliminates these dependencies by design.
