To install and activate a plugin you need to stop your lightningd and restart it with the plugin argument like this:

lightningd --plugin=/path/to/plugin/directory/


  • The must have executable permissions: chmod a+x
  • A plugin can be written in any programming language, as it interacts with lightningd purely using stdin/stdout pipes.

Automatic plugin initialization

Alternatively, especially when you use multiple plugins, you can copy or symlink all plugin directories into your ~/.lightning/plugins directory. The daemon will load each executeable it finds in sub-directories as a plugin. In this case you don't need to manage all the --plugin=... parameters.


To simplify plugin development you can rely on pyln-client for the plugin implementation, pyln-proto if you need to parse or write lightning protocol messages, and pyln-testing in order to write tests. These libraries can be retrieved in a number of different ways:

  • Using pip tools: pip3 install pyln-client pyln-testing
  • Using the PYTHONPATH environment variable to include your clightning's shipped pyln-* libraries:
export PYTHONPATH=/path/to/lightnind/contrib/pyln-client:/path/to/lightnind/contrib/pyln-testing:$PYTHONPATH

Writing tests

The pyln-testing library provides a number of helpers and fixtures to write tests. While not strictly necessary, writing a test will ensure that your plugin is working correctly against a number of configurations (both with and without DEVELOPER, COMPAT and EXPERIMENTAL_FEATURES), and more importantly that they will continue to work with newly release versions of c-lightning.

Writing a test is as simple as this:

  • The framework will look for unittest filenames starting with test_.
  • The test functions should also start with test_.
from pyln.testing.fixtures import *

pluginopt = {'plugin': os.path.join(os.path.dirname(__file__), "")}

def test_your_plugin(node_factory, bitcoind):
    l1 = node_factory.get_node(options=pluginopt)
    s = l1.rpc.getinfo()
    assert(s['network'] == 'regtest') # or whatever you want to test

Tests are run against pull requests, all commits on master, as well as once ever 24 hours to test against the latest master branch of the c-lightning development tree.

Running tests locally can be done like this: (make sure the PYTHONPATH env variable is correct)


Additional dependencies

Additionally, some Python plugins come with a requirements.txt which can be used to install the plugin's dependencies using the pip tools:

pip3 install -r requirements.txt

Note: You might need to also specify the --user command line flag depending on your environment.
