Client library for lightningd

Project description

pylightning: A python client library for lightningd

This package implements the Unix socket based JSON-RPC protocol that lightningd exposes to the rest of the world. It can be used to call arbitrary functions on the RPC interface, and serves as a basis for plugins written in python.


pylightning is available on pip:

pip install pylightning

Alternatively you can also install the development version to get access to currently unreleased features by checking out the c-lightning source code and installing into your python3 environment:

git clone
cd lightning/contrib/pylightning
python3 develop

This will add links to the library into your environment so changing the checked out source code will also result in the environment picking up these changes. Notice however that unreleased versions may change API without warning, so test thoroughly with the released version.


Using the JSON-RPC client

Generate invoice on one daemon and pay it on the other
from lightning import LightningRpc
import random

# Create two instances of the LightningRpc object using two different c-lightning daemons on your computer
l1 = LightningRpc("/tmp/lightning1/lightning-rpc")
l5 = LightningRpc("/tmp/lightning5/lightning-rpc")

info5 = l5.getinfo()

# Create invoice for test payment
invoice = l5.invoice(100, "lbl{}".format(random.random()), "testpayment")

# Get route to l1
route = l1.getroute(info5['id'], 100, 1)

# Pay invoice
print(l1.sendpay(route['route'], invoice['payment_hash']))

Writing a plugin

Plugins are programs that lightningd can be configured to execute alongside the main daemon. They allow advanced interactions with and customizations to the daemon.

#!/usr/bin/env python3
from lightning import Plugin

plugin = Plugin()

def hello(plugin, name="world"):
    """This is the documentation string for the hello-function.

    It gets reported as the description when registering the function
    as a method with `lightningd`.

    greeting = plugin.get_option('greeting')
    s = '{} {}'.format(greeting, name)
    return s

def init(options, configuration, plugin):
    plugin.log("Plugin initialized")

def on_connect(plugin, id, address):
    plugin.log("Received connect event for peer {}".format(id))

plugin.add_option('greeting', 'Hello', 'The greeting I should use.')
