I know my previous nostr-based payment metadata solution didn't really get adoption from other PC20 apps - so me and Dovydas (npub1gfn…mk8j) have come up with a much simpler solution for LNAddress payment metadata:
https://github.com/Podcastindex-org/podcast-namespace/pull/734
TLDR - we use the BOLT11 invoice description field to add a rss::payment prefix along with a URL that returns the full metadata in a x-rss-payment header.
From today all LNAddress payments sent from Fountain will use this metadata approach - so feel free to start testing!
