Understand the project

Practical overview

When it fits

Use Hub when a Lightning wallet or node needs to be controlled by NWC-compatible applications, or when a self-hosted desktop, web or Docker-based control layer is needed.

Who it is for

  • Bitcoin and Lightning users managing a self-hosted node or wallet
  • Nostr application users who need an NWC-connected Lightning backend
  • Developers building or testing Lightning services with documented local and Docker workflows

Documented uses

  • Connect Damus, Amethyst or another NWC-compatible application to a Lightning node or wallet
  • Operate a desktop Lightning control application on macOS, Windows or Linux
  • Run the HTTP mode through Docker or a supported Linux or Mac environment
  • Configure embedded or external Lightning backends
Before you choose

Requirements & limits

The repository is public and identifies the project as Apache-2.0 licensed. Documented platforms include macOS, Windows, Linux, Docker and web mode.

  • NWC compatibility is required for connected applications to control Hub.
  • The default Lightning backend is embedded LDK; LND, Phoenixd, Cashu and CLN are also listed as supported external backends.
  • Desktop and HTTP modes have different documented platform paths.
  • An always-online machine is described for connections to a Lightning address and receipt of online payments.
  • Development requires Go, Node, npm and Yarn; Wails and platform-specific dependencies are needed for Wails development.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Set up Hub for local HTTP development

Prepare and launch the HTTP mode locally from the repository.

Before you start

  • Go, Node, npm and Yarn
  • A copied .env configuration file
  • Frontend files available for embedding
  • A Lightning Polar setup with two LND nodes for the documented server setup

Steps

  1. Copy .env.example to .env and edit the configuration.

  2. Create a Lightning Polar setup with two LND nodes and enable the Polar LND section in .env.

  3. Compile the frontend, or create frontend/dist/tmp so embeddable files are available.

  4. Build the HTTP binary, place it with .env in a temporary directory, and run the binary.

Expected outcome

A locally launched HTTP-mode Hub process using the repository's documented setup path.

Guide limitations

  • The instructions describe development and local execution, not a production deployment.
  • The Polar LND setup is part of the documented server-development procedure.
  • No successful execution or compatibility result is established by these instructions.
