The best way to store your hardware wallet backup.

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.
Shuffle the cards to encrypt what's written on their sides.

Pick a 3-digit PIN, and use it to arrange your cards in a particular order.

 

OUR VISION

We’re Here to Level Up Your Seed Phrase Storage

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. It takes 15 to 30 minutes.

02  WRITE YOUR SECRET PHRASE

Write your secret phrase on the sides of the deck. The ink soaks into the cards, so it can't be erased.

03  SHUFFLE THE CARDS

Your secret phrase will be encrypted as you shuffle the cards. Use your PIN to put the cards back in position and read your secret.
