BTCIOT - DIY Bitcoin Hardware Wallet, Part 1 *Goomba* (only $5!)
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:

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.
