A novel solution to an inherently digital problem

Secure your seed phrase backup by physically encrypting it with a simple shuffle.

​

Chaindeck is a unique deck of 100 cards offering the best way to store your seed phrase. 

Two hands holding Chaindeck cards for seed phrase backup storage. The cards are inside a paper sleeve and being pulled out.

OUR VISION

We’re Here to Level Up Your Seed Phrase Storage

Pick a 3-digit PIN, and use it to arrange your cards in a particular order.
 
After writing your seed phrase on the sides of the deck, shuffle the cards thoroughly to encrypt what's written.

Watch your seed phrase turn into gibberish as you shuffle the cards.

Following the initial shuffling, you can introduce false markings on empty spaces to improve the security of your Chaindeck.

HOW DOES IT WORK?

A smarter way to protect your seed phrase

01  CHAIN YOUR DECK

Pick a 3-digit PIN and follow the instructions to arrange the cards in a specific order. 

02  WRITE YOUR SECRET PHRASE

Place the chained cards in the sleeve to easily hold the deck. Using a black marker, write your secret phrase on the sides of the deck.

03  SHUFFLE THE CARDS

Your secret phrase will be encrypted as you shuffle the cards.
