IOTA ESP32 Wallet

Now that CClient v1.0.0-beta is released, IOTA can implement a hardware wallet based on it. I will, in this blogpost, briefly explain the architecture of the IOTA Wallet on ESP32 and I will demonstrate the wallet application.

Introduction

The CClient library is meant to apply the Tangle into IoT ecosystems. It is able to communicate with small devices. The ESP32 is a good candidate because it has built-in wireless connectivity.

But what’s the ESP32?

  • It is a 32bit SoC (System on Chip) based on the Xtensa LX6
  • It is able to operate at 160 or 240 MHz with the memory size of 512KB
  • It provides two development frameworks: arduino-esp32 and esp-idf. Even if both of them are good, I prefer the esp-idf as my development framework since it’s native to the ESP32.

The IOTA ESP32 Wallet

The wallet architecture consists of three parts:

  • Hardware: the Xtensa LX6 processes and peripherals
  • FreeRTOS: real-time system, network, and HAL support
  • Wallet application: IOTA CClient library, SNTP client, and Console service.

The system time will be reset on reboot every time, so we need to get the correct timestamp via SNTP client. The console service allows you to interact with IRI node through the terminal.

You can follow the README.md to create your IOTA wallet using ESP32 microcontroller.

A MESSAGE FROM THE BOARD

As planned Sergey Ivancheglo, better known as Come-from-Beyond/CFB, submitted his resignation letter on the 26th of June and stepped down from the Board of Directors. Since then he has handed over some backlogged work in the role of an unofficial advisor to the Foundation but holds no position in the organization.
As everyone knows, CFB has been and continues to be one of the most prolific and influential people in crypto and has served an absolutely pivotal role in the IOTA project. We fully support his decision to depart and are very grateful to Sergey for all his contributions to the Foundation and look forward to a fruitful collaboration with him in his role as an independent developer.
