What is Seedkeeper?

Seedkeeper is a smartcard device that can be used to securely store seeds and other sensitive data for long term protection.

Traditionally, cryptocurrency users have used a simple pen and paper to keep a backup copy of their hardware wallet seed.

While this simple method works relatively well, it has also signifiant drawbacks:

  • A piece of paper can be easily lost, damaged or destroyed;
  • The seed is usually written in plaintext, since encryption is not practical.

With a Seedkeeper, seeds are stored in the smartcard secure memory and can only be accessed by their legitimate owner using a short, easy-to-remember, secret PIN code. Seedkeeper is easy to use yet powerful; it is robust yet affordable; and last but not least, it is completely open-source.

Seedkeeper can be conveniently used in combination with a Satochip hardware wallet to serve as a secure backup.
And you can use multiple Seedkeeper backups without compromising security!

Overview

The main purpose of a Seedkeeper is to securely store and backup seeds.

On a basic level, here are the main actions you can perform on a Seedkeeper:

  • Generate a new (random) mnenomic with the tool and store it on your Seedkeeper card;
  • Generate a new (random) masterseed directly on the Seedkeeper;
  • Export a seed stored in the Seedkeeper to setup a new Satochip hardware wallet.

A Seedkeeper can store several seeds in its secure memory (up to a dozen).

    • Mnemonic phrase;
    • Masterseed;
    • JSON file;
    • Authentikey;
    • Trusted Pubkey;
