Moonshine

Moonshine is available on iOS & Android

Website: moonshinewallet.com

Moonshine is a homebrewed, open-source, non-custodial, Bitcoin/Litecoin Electrum wallet for iOS & Android.

Built with React Native, Moonshine utilizes Electrum's JSON-RPC methods to interact with the Bitcoin/Litecoin network.

Moonshine's intended use is as a hot wallet. Meaning, your keys are only as safe as the device you install this wallet on. As with any hot wallet, please ensure that you keep only a small, responsible amount of Bitcoin/Litecoin on it at any given time.

If you are looking for secure cold storage solutions please consider purchasing a Trezor or a Ledger

Installation

1. Clone Moonshine and Install Dependencies: git clone https://github.com/coreyphillips/moonshine && cd moonshine && yarn install
2. Start the project:
   • iOS: react-native run-ios
   • Android: react-native run-android

Create Your Own Build

• git clone https://github.com/coreyphillips/moonshine && cd moonshine && yarn install && yarn bundle

Create a Reproducible Build

This method requires docker to create a reproducible build and takes quite some time. However, it will allow you to verify against the most recently available build on Google Play.

A few things to note though. First, this method only works if using the same version that is currently available on the Play Store. Second, you'll need to be sure that you're comparing the correct apk files depending on the device you're using (x86, x86_64, v7a, arm64-v8a). Third, make sure you're building with a clean, unmodified clone of moonshine by following the steps below. Modifying the code in any way will result in a failed apkdiff.py check.

1. Clone and cd into the latest release:
   • basename $(curl -Ls -o /dev/null -w %{url_effective} https://github.com/coreyphillips/moonshine/releases/latest) | { IFS= read -r tag; git clone -b ${tag} https://github.com/coreyphillips/moonshine; }
   • cd moonshine
2. Run docker and create the build. Once built, the apks will be located in "moonshine/android/app/build/outputs/apk/release/":
   • docker run --rm --name moonshine-build -v ${PWD}:/pwd -w /pwd coreylphillips/react-native-android bash -c "source ~/.bash_profile && yarn install && cd nodejs-assets/nodejs-project && yarn install && cd ../../android && ./gradlew clean && cd .. && yarn bundle"
3. Fetch the apk from Google Play using a service of your choice. I've listed a few below:
   • https://github.com/rehmatworks/gplaydl
   • https://github.com/onyxbits/raccoon4
   • (Web-based) https://apkbucket.net/apk-downloader/
4. Use apkdiff.py to compare the apk files. Example usage:
   • python apkdiff.py googleplay.apk local.apk

Altcoin Support

Please be aware and take note that my primary focus is on expanding the core functionality of this wallet and not on adding altcoins. However, for those wishing to add a specific altcoin for personal use, I have created the following guide so that you may fork off in a proper fashion: Altcoin Implementation Guide

If you have any questions regarding this guide I'm always happy to help so don't hesitate to reach out.

Support

Supported Derivation Paths: m/44' | 49' | 84' /0'/0'

Again, if you have any questions, feature requests, etc., please feel free to create an issue on Github, reach out to me on Twitter or send an email to [email protected].
