lnbits-flask

This is a barebones flask web application that accepts lightning payments and withdrawals.

It wraps calls to an LNBits wallet, configured in flaskapp.py:

 lnbits_kwargs = {
  "host": "http://YOUR LN NODE TOR ADDRESS.onion",
  "walletid": "YOUR LNBITS WALLET ID HERE",
  "adminkey": "YOUR LNBITS ADMIN KEY HERE",
  "invoicekey": "YOUR LNBITS INVOICE KEY HERE",
  "tor": True
 }

LNBits behind Tor (e.g. Umbrel node)

Set tor=True, if LNBits host is an onion address.

You must have Tor running on the flask host.

You must have pysocks installed, to support Tor connection via socks5 proxy.

Requirements

  • LNBits wallet
  • Python module: pysocks
  • Python modules: bolt11 (https://github.com/nievk/bolt11 - for decoding bolt11 invoices, to check withdrawal amounts)
  • Tor running on host

How to run

  • Install requirements above
  • Customize lnbits_kwargs in flaskapp.py
  • $ python3 flaskapp.py

It's possible to add payment detection on QR invoice page, using LNBits webhooks and flask_socketio... but that was left out to keep the example simple.
