A core Lightning LSPS implementation

Warning

This is code experimental and using it might result in loss of funds

• The LSP-spec isn't final yet and breaking changes might occur.
• No code in this repository has been formally peer review (yet).

This is a Core Lightning implementation for the Lightning Serverice Provider Specification or LSPS for short.

The LSP-spec standardizes how LSP-clients and LSP-servers interact. LSP-clients can purchase channels from LSP-servers to ensure they are well-connected to the network and can receive payments.

This repository contains

• lsp-primitives: a rust crate with basic primitives to implement an LSP-code
• lsps-client: A Core Lightning plugin that implements an LSP-client
• lsps-server: A Core Lightning plugin that impelments an LSP-server

Current support

Spec	Features	Client-support	Server-support
LSPS0	Transport layer	Yes	Yes
LSPS1	Order a channel	Yes	Yes
LSPS1	Pay order with Lightning	Yes	Yes
LSPS1	Pay order onchain	No	No

This repository aims to provide

• a high quality client implementation for Core Lightning (plugins/lsps0-client)
• a library that can be used to implement your own LSP-client or LSP-server (libs/lsps-primitives)

The LSP-server should not be used in production. It serves as a testing-ground for the LSP-client and has been developped for that purpose. However, I welcome any contribution that helps to make it production ready.
