This is a client library for ledger-app-hns. It uses primitives from hsd.

$ git clone https://github.com/handshake-org/hsd-ledger.git
$ cd hsd-ledger
$ npm install

When requiring hsd-ledger as a dependency in your project, you MUST also install hsd, either globally (npm i -g hsd) or require hsd as a sibling dependency along side hsd-ledger. This is effectively how peerDependencies worked in npm version 4 through 6, but starting with npm v7, those dependencies are installed, usually a second time, causing instanceof checks to fail.

There are two ways to use this library to interact with a Ledger device:

• using HID from Node.js
• using WebUSB in the browser

Example usage can be found and run using the following files:

• examples/getAppVersion.js - Get the application version number.
• examples/getAccountXPUB.js - Get a BIP44 account xpub.
• examples/getXPUB.js - Get an arbitrary xpub.
• examples/getAddress.js - Get a BIP44 compliant address.
• examples/getPublicKey.js - Get a BIP44 compliant address.
• examples/signTransaction-p2pkh.js - Sign P2PKH transaction.
• examples/signTransaction-p2sh.js - Sign P2SH transaction.
• examples/webusb/index.js - WebUSB.

There is a CLI tool, in the bin directory, that can interact with a Ledger device and an hsd full node. The docs are here.

$ npm test

For all end-to-end tests, a LOG_LEVEL environment variable can be set to control the log output. Possible log levels include: none, info, warning, debug, error, spam.

Note: the end-to-end tests require a connected Ledger Nano S using the seed phrase:

abandon abandon abandon abandon abandon abandon
abandon abandon abandon abandon abandon about

$ npm run test-hid

$ npm run test-hsd
