Accessible and secure Bitcoin cold storage

IcyWallet is a Bitcoin cold storage wallet that doesn’t require sight. It aims to be the simplest and most secure Bitcoin cold storage solution with a total emphasis on accessibility. Just plug in headphones and a keyboard, or a refreshable braille display, and get going.

Project Status

As of February 3, 2019, core API work is under development. This will serve as the backbone for both the web and terminal interfaces. Watch this space for updates, or keep an eye on the GitHub repoisotry to view the latest in-progress code.


  • 100% free and open source
  • Boots directly into the wallet app with functioning audio and braille support (via BRLTTY)
  • All interactions designed to create the best possible accessible experience
  • Generates hierarchical deterministic wallets with mnemonic seeds for safe backup
  • Generates SegWit addresses

How It Works

The IcyWallet software is designed to run on a Raspberry Pi, specifically one that will never be connected to the internet (a so-called air gapped device). In theory you could run the software on anything, but everything has been designed with the Pi in mind. IcyWallet will securely generate private keys and store them on the device, and issue a mnemonic seed for safe and convenient backup.
