Ledger squid Plugin

This is a plugin for the Ethereum application which helps parsing and displaying relevant information when signing a squid transaction.

Prerequisite

Clone the plugin in a new folder.

git clone https://github.com/blooo-io/LedgerHQ-app-plugin-squid.git

Then in the same folder clone two more repositories, which is the plugin-tools and app-ethereum.

git clone https://github.com/LedgerHQ/plugin-tools.git                          #plugin-tools
git clone --recurse-submodules https://github.com/LedgerHQ/app-ethereum.git     #app-ethereum

Build

Go to the plugin-tools folder and run the "./start" script.

cd plugin-tools  # go to plugin folder
./start.sh       # run the script start.sh

The script will build a docker image and attach a console. When the docker image is running go to the "LedgerHQ-app-plugin-squid" folder and build the ".elf" files.

cd LedgerHQ-app-plugin-squid/tests    # go to the tests folder in app-plugin-squid
./build_local_test_elfs.sh            # run the script build_local_test_elfs.sh

Tests

To test the plugin go to the tests folder from the "app-plugin-squid" and run the script "test"

cd LedgerHQ-app-plugin-squid/tests    # go to the tests folder in LedgerHQ-app-plugin-squid
yarn test                             # run the script test

Continuous Integration

The flow processed in GitHub Actions is the following:

• Code formatting with clang-format
• Compilation of the application for Ledger Nano S, Nano S+ and Nano X in ledger-app-builder
• Execution of the provided end to end tests
