Connecting ZEUS to your node

You can connect ZEUS to a remote Bitcoin Lightning node running Lightning Network Daemon (lnd), eclair, or Core Lightning using the REST or Sparko API.

You must provide ZEUS with your node’s hostname, port number, and the macaroon you choose to use in hex format. If you need help converting your macaroon to hex format we wrote up a Node.js script that can use here. Alternatively, if you’re running a Unix-based operating system (eg. macOS, Linux) you can run xxd -ps -u -c 1000 /path/to/admin.macaroon to generate your macaroon in hex format.

Tor Connection Guides

ZEUS has support for connecting to you node entirely over the Tor network. You can refer to these guides to set up a Tor hidden service on your lnd node. The instructions are generally interchangeable and typically only require you to change your Tor path.

Starting development

Don’t trust, verify the code with your own two eyes. Then when ready proceed to the steps below based on your platform.

Prerequisites

• Node.js (minimum version: 18.18)

Android

1. install and setup react-native and its related dependencies under “Building Projects with Native Code” on react-native’s Getting Started page
2. if using your phone, enable Developer mode and USB Debugging , then make sure it is connected to your computer by running adb devices
3. install node dependencies with yarn
4. open up your Android simulator or connect your phone and run npx react-native start
5. open a new tab and run npx react-native run-android

iOS

1. install and setup react-native and its related dependencies under “Building Projects with Native Code” on react-native’s Getting Started page
2. install node dependencies with yarn
3. cd ios && pod install
4. open ios/zeus.xcworkspace in Xcode and hit Run.

Contributing

Please be sure to run yarn run tsc to check for type errors, yarn run test to run all tests, and yarn run prettier to run the prettier

If you are making cosmetic changes please test on both Android and iOS as things don’t render exactly the same on both platforms.

If you’re looking for a quick way to get a lightning development environment running, check out Polar.

NOTE: When configuring a new node on Android in dev, the Host field must be 10.0.2.2 - 127.0.0.1 or localhost won’t work.
