Operate a C-lightning node

Core Lightning API Reference (all methods)

Prerequisites

• Running a Bitcoin full node on the same computer.
• Install C-lightning

Config lightningd

Create or open file ~/.lightning/config

bitcoin-datadir=/mnt/Bitcoin/
bitcoin-cli=bitcoin-cli
log-file=log.debug
log-level=debug
daemon
network=bitcoin
rgb=f6ae99
alias=PickAName
bind-addr=LAN ip
announce-addr=WAN ip or dns

Start node

Just start lightning daemon by:

lightningd

Operations

Get info

lightning-cli getinfo

gives you number of channels and peers. If 0 you should start by connecting to at least one node

lightning-cli listaddresses

new address

lightning-cli newaddr p2tr

Send on-chain

lightning-cli withdraw bc1... all

on-chain funds

lightning-cli listfunds

Connect to peer

This is free, it's just the peer and gossip connection kind of like the bitcoind does by itself, nothing to do with payments yet

Go to 1ML and find a suitable node

lightning-cli connect 0217890e3aad8d35bc054f43acc00084b25229ecff0ab68debd82883ad65ee8266@23.237.77.11:9735

List peers

lightning-cli listpeers

List channels

This might give you shit loads of channels, but it verifies that you are online

lightning-cli listchannels

Close channel

Will become a unilateral close after the timeout

Example for 10 minutes timeout

lightning-cli close 976bbeb5f244cbc9b9669dc97620b459444f3712b8eebca0309c7292bfa5add7 600

Add this to config

clnrest-port=9738
clnrest-host=172.24.0.5
