Here is a boilerplate plugin to help you write your own. This guide walks you through the plugin.
You can follow it best by forking the repository app-plugin-boilerplate (opens in a new tab).
cd .. git clone --recurse-submodules https://github.com/LedgerHQ/app-plugin-boilerplate
There is no need to build it right now, only after adding tests. For now, in
app-plugin-boilerplate/ there are these folders:
ethereum-plugin-sdk: This repository contains information shared by the Ethereum app and your plugin, such as structure definitions, utility functions, etc.
glyphs: plugin icons as displayed on the device. We will get to it later, but you can read about it here.
src: the actual source code (in C).
tests: the test folder (using the Ragger testing framework).
.github/workflows: the CI workflows which are a requirement to submit your plugin. To have more details you can refer to this section.
There is the
Makefile directly in the repository root. You need to open
Makefile and change the plugin infos including
APPNAME to suit your plugin name (e.g., Paraswap, 1inch, Lido),
APPVERSION for plugin version and other various infos.
