ESP32 hardware wallet

Koopa - a cheap DIY watch-only bitcoin hardware wallet with epaper (only $15!)

This is an untested truley reckless hardware wallet, we take no responsiblity for loss of funds!

Koopa is a bare bones, build your own hardware wallet, based on the very affordable ($5) ESP32, and MH-ET-LIVE epaper module. The project uses Stepan Snigirev's incredible bitcoin library

Koopa is a slightly altered version of Stepan Snigirev's hack at Bitcoin2019
