### @cardano-foundation/ledgerjs-hw-app-cardano

JS library for communication with Ledger Hardware Wallets running the [Cardano ADA Ledger Application](https://github.com/cardano-foundation/ledger-app-cardano).

See [`doc/overview.md`](doc/overview.md) for architecture and [`doc/testing.md`](doc/testing.md) for how to run tests.

### Example code

Example code interacting with `hw-app-cardano` is provided in `example-node` directory.
You can execute it with the `yarn run-example` command.

### Tooling

This repo uses Corepack with Yarn 4. If `yarn audit` does not work locally, use:

```bash
corepack yarn npm audit --all --no-deprecations --recursive
```

On Linux, `corepack yarn install` may require system packages for `node-hid`:

```bash
sudo apt-get update
sudo apt-get install -y libusb-1.0-0-dev libudev-dev
```
