New Cuvex 2.0 Now on sale in preorder

Maintaining the same robustness in security while adding new functionalities

We are thrilled to announce that our second model is already in the works!

We have put a lot of effort into listening to our customers and thinking carefully about how to implement all

possible improvements to our initial model. As a result of this effort, we present to you Cuvex 2.0.

Cuvex 2.0

New features

Biometric access with fingerprint

Firmware update process via USB-C cable from our Cuvex App for Smartphones.

Cuvex 2.0 acquires Hardware Wallet capabilities with the new AirGap PSBT signing functionality.

Deliveries for the first half of 2025


Access control to Multi-Signature and Single-Signature

cryptograms through fingerprint recognition

We have implemented an additional layer for accessing encrypted secrets: the biometrics of the rightful owner.


We have integrated a state-of-the-art biometric sensor capable of creating the template of the fingerprints of authorized users necessary to access the decrypted cryptogram.


 Now Multi-Signature and Single-Signature users can choose to add, in addition to the password used for encryption, a biometric access control.


This functionality allows for using a single password for encryption, even if multiple people are required to be present for decryption. The system will request, in addition to the password, each of the fingerprints of the individuals required to decrypt and view the encrypted secret.


Firmware update process via USB-C cable from our Cuvex App for Smartphones.

We have removed the Bluetooth module installed in the hardware.


 We have done this for two reasons:


* To improve firmware installation times 


* To provide our customers with what they have requested.
