So I decided to start building an open source hardware wallet....specifically for Denarius (D) I decided upon the ESP32 platform chip due to its powerful feature set enabling the use of cryptographic functions and cheap cost. We have options of Wifi and Bluetooth if needed, though the focus will be around not enabling these on the board. The code is very basic as this is my first time with playing with MCUs and development micro controller boards. Everything will be released in due time as well as this post updated, this thread will serve as a historical and discussion venue. Some early prototyping with a breadboard + ESP32 Dev Board + 128x32 OLED display Some serial console output of some transaction signing attempts on chip
