Why Cuvex?

Safest Seed Phrase Recovery

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. 

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.

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.
