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.

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:
- Import an existing seed on the 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).
A label can be attached to each seed stored in secure memory.
This can be used to provide a short description (in less than 128 characters).
