This is a custom firmware for the Solo Key that turns it into a cryptocurrency hardware wallet.
This is not fully featured and HAS NO WAY TO BACK UP YOUR KEYS
- This is experimental software - it might break at any moment and you'll lose your coins
- There is, as of yet, no way to back up your wallet - you lose the key, you lose the coins
- In order to flash this, you need an unlocked version of the Solo key, which removes firmware signing. A bad actor can just reflash your key with firmware that exposes the private key.
