https://github.com/micro-bitcoin/uBitcoin The process of building the full hardware wallet will be split across a few tutorials. In this second tutorial, we build a very simple watch-only hardware wallet, which also has an epaper display. The display is capable of showing new addresses, and keeping the address visible even when the unit is powered off! https://github.com/arcbtc/koopa Follow me:
