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.
