Sidekick is a new companion app that you can install on a secondary phone to authorize access to your Monero wallets in Monerujo. That way, as long as you keep that phone offline, it works as a DIY hardware wallet.
Features:
Free: no payments or subscriptions to use it.
Open Source: code available for anyone to inspect.
Safer: avoids signaling you out as a hardware wallet owner.
Secure: encrypted Bluetooth communications and wallet files.
Accessible: use your color touchscreen to operate it comfortably.
Fair: provides access to very strong security to anyone with a basic smartphone.
Green: a second life for your unused gadgets.
