Implement the @npub1yv3yqhzql8n9sj3zndulzdtx7axlcs6y2k2aun6qau7qmyvr8umsljm9zn concept! Trivial Nostr DM bot that will provide a payment addr (or could be an LN invoice) on request.
Defeat firewalls and other barriers via Nostr simplicity without relying on Tor. Someone could run a fundraising campaign within BTCPay but with no exposed webserver whatsoever. Just pull its associated Nostr DMs and respond.
Simple bot prototype already written in python (see linked github repo).
