Your right, it wasn’t a useful response.

My badly made point was that LNbits is just a client to post market place products to relays. I’m sure other clients will come along that do it (I hope so) - if not already. No reason a simple mobile app can’t post marketplace products for example.

Not sure if there are any NIPs out there for onchain (or otherwise), and I haven’t heard of a client that supports anything other than Lightning. Maybe when marketplaces become more prevalent it would be a good use case for Monero.
