lunlumo

A python3 GUI for Monero with automated cold transaction signing via QR code streams.

by u/NASA_Welder

Current Features

Full Monero GUI for desktop Linux and Raspberry Pi (armv7)
Automated Cold signing via QR code stream + webcam between Hot(watch-only wallet) and air-gapped (full wallet) machines
Send / Receive normally via daemon connection with Hot full wallet
Account Switching
Subaddress selection and generation
Comes with a python wallet-cli wrapper library that can be used standalone for your other needs (API not stable yet, but certainly useable)

Roadmap

Multisig cold-generation and cold-signing automation
Wallet meta-data transfer and backup (saving/transferring address book and subaddress info separately from keys for transfer/backup/merge)
GUI features added for monero cli functions
Scan address via QR code. (Just hadn't gotten to this, yet)
Integration with android / iOS apps
arbitrary file transfer via QR in a standalone library
Formal API for cli-wrapper library
Bundle all dependencies with source for easier trust verification.

Dependencies

lunlumo wraps the monero-wallet-cli. You must download the offical binaries from www.getmonero.org Note: The goal is to eventually provide all dependencies via this github account for simpler trust verification.

The following assumes Ubuntu Mate:

sudo apt-get install python3-tk # this comes standard on some distributions, including ubuntu mate for raspi.
sudo -H pip3 install Pillow --upgrade # >= 3.4
sudo apt-get install libzbar0 libzbar-dev
sudo -H pip3 install setuptools --upgrade
sudo -H pip3 install zbarlight
pip3 install --upgrade pip
sudo apt-get build-dep python-pygame
sudo apt install python-dev
sudo -H pip3 install pygame
sudo usermod -a -G video timepi # raspi only

Hardware / Setup

The GUI can be used standalone, on an internet connected computer for normal transaction usage, however, lunlumo's intended purpose is to allow cold transaction signing via QR code stream between 2 computers.
