Opening a channel by using a PSBT

This document describes how to open a channel with c-lightning by using a PSBT as the funding transaction for my learning. If you use lnd please go to here that is well documented. Also, here is the c-lightning offical document for each command that are shown below.

1. Start a funding process

fundchannel_start is a lower level RPC command that allows a user to initiate channel establishment with a connected peer. Assume my node is already connected to 02b861cc95a061d0536a2e6d96992274c284490bc1e3782d5b59004a2aba7767a7. Below the command returns the funding_address and the scriptpubkey for the channel funding output with 200000 sats.

	from glclient import TlsConfig, Scheduler, Signer

	seed=b'my-seed'
	cert = "my-cert"
	key = "my-key"

	node_id = bytes.fromhex("02a5b6a3fe53c39edb348818b4a145c830db90cbc410ac52ce16e985e7f0b37e86")
	network = "mainnet"
	tls = TlsConfig()
	tls = tls.identity(cert, key)
