Why Cuvex?
Safest Seed Phrase Recovery
Stored with Cuvex
Seed becomes an encrypted secret into NFC Card.
Distributed storage in many copies as you wish.
Multi-signature for seed or secret encryption.
NFC Card Durability is around 10 years.
This is real sovereign and secure self-custody.
Seed Phrase Stored as Clear Text
Writing in paper is vulnerable, humidity, water, fire...
Carving in steel does not prevent theft.
Taking a picture is enough for a thief.
Uploading to the Cloud opens the door to hacking.
Giving it to third partys is not self-custody.

You have true custody and ownership of your Cryptoassets, only if you have access to your seeds or private keys Offline
We have designed and patented Cuvex, to create a cryptogram with your private keys that a
supercomputer could take more than 10,000 years to break.

What you can do with Cuvex?
Manage Cards
Read via NFC the UID of your cards and assign them an "Alias”.
Register the Alias in the "Cuvex App" secure element and keep a private inventory.
Encrypt
Encrypt with AES 256, your private keys, seeds or the coordinates of your buried treasure ;).
Establish mono or multi-signature access control and record the cryptogram into NFC card. All this, without internet connection and without depending on anyone else.
Decrypt
Read any Cuvex card with any Cuvex device, either to access your secret or for control purpose. You will need the mono or multi-signature password to decrypt the secret.
Display the seed in text / QR, so you can sign transactions in your Hardware Wallet.
Clone Cards
You can make as many copies of Cuvex cards as you need. A clone of a card simply copies the Cryptogram to another card. It does not decrypt it nor does it allow you to modify anything. You can send copies to different physical locations, guaranteeing redundancy.
Update
Our App informs you when there is a firmware update.
The device links via BLE with our App, through P2P encryption.
After receiving the update, the Cuvex
device disable the Bluetooth module. The Firmware update is performed in cold after digital signature validation.

Multi-signature security access to your private keys and seeds
Mono-signature or multi-signature access, whether you guard your own Wallet, or if you guard one shared with family or partners, you can establish up to six people necessary to decrypt the cryptogram of your seed.
Each necessary person will establish their own Password and will be asked to decrypt.
It guarantees that all authorized persons are necessary to decrypt and
visualize the private key or encrypted seed.
The Cuvex device will show you the seed or private key in text or QR format.

Storage and cloning of cryptograms on NFC cards
The engraving of your cryptogram on an NFC card guarantees you a durable, safe and economical custody.
You can clone copies of the cryptogram of your seeds at the lowest cost of today without limits, with a memory life of up to 10 years.
No one can have visual access to them, you will no longer have them written
down on paper or carved in steel, but even if your cards are lost or stolen, the AES 256 cryptogram protects your information with the maximum security that the industry allows today.

Don't trust Cuvex!
Trust nobody
We can tell you about the three years of research and development, about how we have managed to patent our technology globally, about the several million dollars invested, and that you have full access to the source code...
All of this and much more is true, but for you, at this moment, they are just words.
You are about to encrypt your seed phrase using a system that relies on a physical device, which naturally raises a critical question: What happens if I lose, damage, or, for any reason, cannot access this device? How do I retrieve my seed phrase and decrypt the cryptogram?
We’ve worked hard and innovated to address this concern. We have developed a desktop application that enables the decryption of any cryptograms created with version 1.1.0 or later of the Cuvex device firmware, without requiring a Cuvex device.

Complete independence!
All you need to do is download the desktop application from our GitHub. You also have the option to download the complete source code for the desktop application as an additional backup.
This solution gives you complete independence from Cuvex for the future. However, it’s essential to strictly follow the app verification steps and make sure you’re installing and running the original, unaltered software.
Please start by consulting our "Desktop App Manual" to fully understand how it works, how to verify the app, and what security precautions to take when using it. There’s no more secure environment for encrypting and decrypting your secrets than the Cuvex device and the cryptogram-encoded cards. With this new tool, you gain greater freedom and full independence from Cuvex, but it should only be used when truly necessary.
