CREATE
BTC WALLET

Do you have a seed phrase that was created by a third party? Do you fully trust it?
 

Create a 100% offline BTC wallet, participating in the entropy process of the seed phrase manually and physically, using the "Dice and Coin" standard, which ensures the highest quality seed phrase creation.


Software-generated seed phrase systems have proven unreliable, with documented cases of errors caused by iterative processes.

BE FREE

Experience the journey of traveling with nothing and having it all; you encrypt your seed phrase with military-grade cryptography and store it on NFC cards.

Export the binary of your cryptogram from the mobile app and decrypt it using the Cuvex desktop app, without needing a Cuvex device.

Firmware, software, and hardware are fully verifiable. Visit our GitHub

  • The Cuvex device uses AES-256-GCM encryption to provide maximum security, ensuring that your crypto seed phrase is fully encrypted and stored on a completely isolated Cuvex NFC card.

    The device does not retain any data after processing, and it does not connect to networks, the cloud, or any peripherals ensuring your crypto seed remains private and secure at all times.

  • The AES-256-GCM encryption algorithm and the device’s hardware architecture guarantee the creation of a cryptogram of the highest quality. The device does not store any information; all processes are performed without any connection to external devices and without an internet connection. Storage on a Cuvex NFC card is inherently secure, since only the encrypted cryptogram can be accessed and it is encrypted before being stored to the card.

    AES-256 is considered one of the most secure encryption algorithms available today. According to several published studies, a modern supercomputer would require more than 10,000 years to break an AES-256 cipher. This is the same encryption standard used for military and government-level protection.

    Our code is public, and anyone can audit it. Despite the device including a secure hardware element to process information, no data is ever stored on it. The only requirement is that you remember your passwords if you forget them, neither we nor anyone else can help you recover your secret.

  • Any card containing a Cuvex cryptogram can be decrypted using any Cuvex device, provided you have the passwords used during the encryption process. If you lose access to these passwords, neither we nor anyone else can assist you in decrypting your secret.

    The AES-256-GCM algorithm, implemented via hardware, is a military-grade encryption standard widely used across public and private industries.

  • Yes, you can even encrypt plain text not linked to crypto assets.
    With Cuvex, you can encrypt any secret, private key, or seed.
