Note: Only the third mint function is labelled as v2 because the first two share the same selector and behave identically.

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-nft" folder and build the ".elf" files.

cd LedgerHQ-app-plugin-nft/tests       # go to the tests folder in LedgerHQ-app-plugin-nft
./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 "LedgerHQ-app-plugin-nft" and run the script "test"

cd LedgerHQ-app-plugin-nft/tests       # go to the tests folder in LedgerHQ-app-plugin-nft
yarn                            # install dependencies
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 in ledger-app-builder
