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/uBitcoin The process of building the full hardware wallet will be split across a few tutorials. In this first tutorial, we build a very simple watch-only hardware wallet. As part of the building process, we learn about the difference between deterministic/non-deterministic wallets, key derivation and entropy. https://github.com/arcbtc/goomba Follow me:
