Hive wallet application framework for Ledger Nano S/X

When installed on a Ledger Nano S/X device, this application will deserialize transactions and display them on the hardware wallet for secure validation by the user. If the user accepts the transaction, this application will then sign the transaction with the key specified by the user.

There is a pre-compiled binary available in the bin/ folder and attached to each public Github release. However, you may optionally choose to compile the Hive Ledger Nano S/X application manually with help of the provided run script. Usage instructions and examples are contained within this README as well as in the test/ folder.

Latest Stable Release

https://github.com/netuoso/ledger-app-hive/releases/tag/v1.0.0

Building the Development Version

• Clone this repository
  • git clone https://github.com/netuoso/ledger-app-hive
• Install Docker if not already installed
  • ./run.sh install_docker
• Pull the latest ledger-app-hive docker image
  • ./run.sh update
• Start the Docker container
  • ./run.sh start
• Build the ledger-app-hive application
  • ./run.sh build VERSION # replace VERSION with 1.4,1.5,1.6 based on your Ledger Nano S firmware

Loading the Compiled Development App on a Ledger Nano S

• Connect the Ledger Nano S to your computer
• Install the Ledger python3 module
  • pip install ledgerblue
• Load the application onto the Ledger Nano S
  • ./run.sh load VERSION # replace VERSION with 1.4,1.5,1.6 based on your Ledger Nano S firmware

Building and loading the App with Ledger-Vagrant

This works only for Ledger Nano S with 1.6.x Firmware installed. To use it, you will need Vagrant and VirtualBox. For USB passthrough, VirtualBox Extension Pack should also be installed.

git clone https://github.com/christophersanborn/ledger-vagrant
cd ledger-vagrant
vagrant up

You can now connect with

vagrant ssh

You need the following packages

sudo apt-get install libsecp256k1-dev  libffi-dev automake libgmp-dev  build-essential libtool python3-pkgconfig
SECP_BUNDLED_EXPERIMENTAL=1 python3 -m pip --no-cache-dir install --no-binary secp256k1 secp256k1
pip3 install ledgerblue

Clone the source code with:

cd apps/
git clone https://github.com/netuoso/ledger-app-hive

and compile it with:

cd apps/ledger-app-hive
make clean
make

Connect your Nano S and enter your pin. Now you can upload the app with:

make load

A make delete removes it again. The following shuts down the machine (from the host)

vagrant halt

Testing the Application

• Navigate to the test directory
  • cd test
• Run the getPublicKey.py script python3 required
  • python getPublicKey.py
• Run the signTransaction.py script python2 required
  • python signTransaction.py

Example Testing Output

• getPublicKey:
