What the publisher says

From the SaturnZap repository's README, as published. We do not edit it. Read it on GitHub

A lightweight, CLI-first, non-custodial Lightning Network wallet built for autonomous AI agents. Self-sovereign. Runs its own Lightning node. No full Bitcoin node required.

<!-- mcp-name: io.github.lqwdtech/saturnzap -->

# One-line install (handles uv + the vendored ldk-node wheel)
curl -LsSf https://raw.githubusercontent.com/lqwdtech/SaturnZap/main/install.sh | sh

export SZ_PASSPHRASE="your-secure-passphrase"
sz setup --auto                  # Generate seed + start node + pick LQWD peer
sz service install               # Keep the node running across reboots
sz connect-info --check          # Share the URI with peers/LSPs

Or install with uv tool directly

uv tool install saturnzap \
  --find-links https://github.com/lqwdtech/SaturnZap/releases/expanded_assets/v1.4.1

The --find-links flag is required because ldk-node==0.7.0.post1 is not yet on PyPI; the SaturnZap GitHub Release ships the vendored wheel.

What is SaturnZap?

SaturnZap is an open-source Lightning wallet designed from the ground up for AI agents operating without human supervision. The agent installs SaturnZap, initializes its own Lightning node, opens channels to any peer on the network, sends and receives Bitcoin payments, and autonomously pays for L402-gated APIs.

SaturnZap is a CLI tool. It is not a hosted wallet, not a custodial service, and not a web application. Keys live on the agent's machine. The agent IS the Lightning node.

Two ways to integrate:

  • CLI — call sz commands from any language, parse JSON from stdout
  • MCP Server — connect AI agents directly via Model Context Protocol (stdio)

Documentation: See the docs/ folder for detailed guides on

JSON API reference.

Business Model

SaturnZap has two layers:

CLI — Open Source (MIT)

The sz command-line tool is free and open source under the MIT license. Anyone can install it, fork it, audit it, and build on it. There is no licensing fee, no API key required to use the software itself, and no telemetry.

LQWD (LSP)

SaturnZap ships pre-configured to use LQWD Technologies as its default Lightning Service Provider (LSP). LQWD operates 18 Lightning nodes across 18 countries with deep global channel liquidity.

When an agent uses LQWD's infrastructure, LQWD earns through:

  • Routing fees — sats earned as payments route through LQWD nodes
  • Channel leasing — fees for opening and providing inbound liquidity to agents
  • Managed connectivity — premium peering and reliability for agents that need it

Shortened. The full README is on GitHub.

Nothing above is checked by us. What we check is on the safety report.
