Over the past 2 years, I have been developing a cold wallet that is:
. affordable to anyone,
. easy to use and transmit to my heir in a trust-minimized fashion.

It only requires a dedicated Android device (any repurposed old Android device will do) that is meant to be kept offline once our app is installed.

The wallet has not been publicly released yet and can only handle btc and eth for now.

Before releasing it publicly, I would appreciate if other people could test it and give me their first impressions. And don't worry, I will send you a few satoshis so that you can test my cold wallet with my money and not yours! ;-) Thanks for your support and good vibes.
