BTCIOT - DIY Bitcoin Hardware Wallet, Part 2 Koopa (only $15!)

Let's build a hardware wallet using a durable, cheap and accessible ESP32!This project was made possible by Stepan Snigirev hack at Bitcoin2019 and his excellent Arduino bitcoin library:https://github.com/micro-bitcoin/uBit...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/koopaFollow me:https://twitter.com/BTCSocialistFollow Stepan Snigirev:https://twitter.com/StepanSnigirev
