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:

  • 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).

  • Import secrets such as:
    • Mnemonic phrase;
    • Masterseed;
    • JSON file;
    • Authentikey;
    • Trusted Pubkey;
    • Various passwords.
  • Export secrets;
  • And list your secrets.

Security

Seedkeeper aims to provide you the best and usable solution to store your secrets.

We don’t mess around with security, which is why your card comes with a range of features to increase the overall security of your equipment while providing unparalleled ease of use.

PIN CODE

Your Seedkeeper card is protected by a PIN code: a 4-16 characters password used to unlock it.

Any sensitive command requires to unlock the device using your personal PIN code.

After the wrong PIN is input several times (typically 4), the device bricks itself and cannot be used anymore!

SECURE PAIRING

The secure pairing allows 2 devices (Seedkeeper, Satochip or any compatible device in the future)
to authenticate each other and generate a shared secret key to communicate securely.

This will allow them to safely exchange seeds and other data.

ENCRYPTED EXPORT

A seed can be exported in two ways, as defined during seed creation:

– In plaintext: the seed is shown in plaintext on the SeedkeeperTool and can be copied to any wallet;

– In encrypted form: the seed is encrypted for a specific device based on the authentikey and can only be exported for that device.
