Plugin App for Ricochet Exchange integration in Ledger Live

Prerequisite

Be sure to have your environment correctly set up (see Getting Started) and ledgerblue and installed.

If you want to benefit from vscode integration, it's recommended to move the toolchain in /opt and set BOLOS_ENV environment variable as follows

BOLOS_ENV=/opt/bolos-devenv

and do the same with BOLOS_SDK environment variable

BOLOS_SDK=/opt/nanos-secure-sdk

Compilation

make DEBUG=1  # compile optionally with PRINTF
make load     # load the app on the Nano using ledgerblue

This plugin uses the ethereum-plugin-sdk. If there's an error while building, try running git pull --recurse-submodules in order to update the sdk. If this fixes your bug, please file an issue or create a PR to add the new sdk version :)

If you need to update the sdk, you will need to do it locally and create a PR on the ethereum-plugin-sdk repo.

Tests & Continuous Integration

The flow processed in GitHub Actions is the following:

Remote VM tests execution

You can test the plugin using a remote development host, if you deal with an unsupported CPU architecture (Ex.: Apple M1). Your server must have a GUI Desktop installed.

Zemu does not support anymore X11 so all screenshots are generated in the snapshot-tmp folder.

Once you replicated the required plugin setup on the remote VM, install the dependencies

cd tests
yarn

Then execute tests:

yarn test
