Lark App
The Lark application is a command line app for interacting with USB hardware wallets in Bitcoin related functions.
It uses the Lark Java library at https://github.com/sparrowwallet/lark, which in turn is a port of the Python library HWI.
The Lark command line application is designed to be a drop-in replacement for HWI, with a subset of commands implemented.
Documentation on the commands is available by running it with --help.
Running
Depending on your operating system, once extracted/installed, Lark can be run from the command line as follows:
Linux
> lark/bin/lark
Note that on Linux, udev rules may need to be installed if you are not using the .deb/.rpm installation package.
macOS
> Lark.app/Contents/MacOS/Lark
Windows
> lark/lark.exe
Example usage
Show usage:
lark --help
Enumerate all connected hardware wallets

Running from source
If you prefer to run Lark directly from source, it can be launched from within the project directory with
./runlark
Java 22 or higher must be installed.
Building
To clone this project, use
git clone --recursive git@github.com:sparrowwallet/larkapp.git
or for those without SSH credentials:
git clone --recursive https://github.com/sparrowwallet/larkapp.git
In order to build, Lark requires Java 22 or higher to be installed. The release binaries are built with Eclipse Temurin 22.0.2+9.
Other packages may also be necessary to build depending on the platform. On Debian/Ubuntu systems:
sudo apt install -y rpm fakeroot binutils
The Lark binaries can be built from source using
./gradlew jpackage
When updating to the latest HEAD
git pull --recurse-submodules
The release binaries are reproducible (pre codesigning and installer packaging).
