Cold storage device for crypto: Security for your seed phrase

We have designed and patented Cuvex, a cold encryption device, meaning it has no connection to the internet or any other device.
With Cuvex, you can create an AES 256 cryptogram that even a supercomputer would take more than 10,000 years to break.
You can securely store your private keys, crypto seed phrase or secrets on NFC cards quickly, cost-effectively and without risk.
Cold Encryption for Seed Phrase recovery hardware. In addition, Cuvex allows you to establish a multi-signature access control to reach the seeds.
This means that the people you configure will need to access your seeds simultaneously, providing an extra layer of security.
It's the perfect solution, for example, if you are practicing AutoCustody for a corporate crypto asset wallet, an investment fund, or a family fund.
Our Welcome Pack includes everything you need, whether you already have Cryptoasset Wallets or if this is your first Self-Custody, Sovereign, and Secure device.

This is the first time I'm heading out on a trip feeling chill. Managed to leave one card at home and always carry the other with me. I don't even sweat it if someone finds them because the info isn't visible anymore, unlike when it was all written down. One less thing to worry about!”

Anthony - USA

The shipping was super fast and the packaging was top-notch! It arrived without a single dent, looking all incredible!

Grace- USA

I don't understand how I could go so many years without one of these. Having my savings written down on a piece of paper is nonsense, now I have copies everywhere and the most wonderful thing is that the key is in my head, that is unconfiscatable and faithful to the true spirit of Satoshi.

Rui - Portugal

I was amazed by how simple it is to encrypt your seed; decrypting it felt like magic. Big props to the Cuvex team for making things easy for those of us who advocate for self-custody.

Alexander - Swiss

When I tried updating the firmware, I hit a snag, so I went straight to the user manual on their website and they had a video that explained everything super clearly. I was able to fix it in no time. My device is an Android, and the push notifications can be a bit of a hassle

Benjamin - USA

The multi-signature solution is killer. We're three partners in the company, and now each of us has their own card and password.

Gian - India

I've really liked the app's functionality for creating a wallet from scratch. I knew other ways, but they required technical know-how. This solution is fantastic and even fun. The best part is being able to transfer the words to the card via NFC, super quick. Good job!

Thomas - USA

More intuitive than I expected, easy to use, but if I had to nitpick, I'd wish it had some biometric feature so I wouldn't even need to remember the password. Well, there's my two cents. I guess they're probably thinking about it.

David - Spain

I am extremely satisfied with both the product and the support from the team. When I received the product, I had some doubts about how to get started with it as I had not thoroughly read the manual. However, the team still provided me with all the guidance I needed.
