Yeah lnaddress/lnurlp is what we want to move towards, but the boost metadata issue has been tricky. Keysend lets you attach arbitrary metadata (TLVs) along with your payment, which is how boosts work right now. The payments and boost metadata arrive directly to your wallet/node without any third-party involvement. Lnurlp doesn't have the same flexibility and only gives you a 200 character comment field to use, which is too small for our purposes. We basically need a service or api or something to store the metadata for each payment and there's no agreement on how that should work. Nostr solved this problem by having the lnurlp server post the metadata back to Nostr as a zap receipt whenever receiving a payment. There's still some ambivalence about using Nostr or any third-party service in the podcast world.

Unfortunately you have to pick one or the other. Alby and Fountain are basically the only two that support keysend, but they're the two that most podcasters use right now. Other wallets like Strike or Primal only support lnaddress and don't support keysend. You can look up the keysend info for a person through the well-known url. For example, my well-known ([email protected]) is at https://getalby.com/.well-known/keysend/ericpp . That gives you my lightning node pubkey and a custom key/value for my wallet (basically a wallet id). You can then use the pubkey, custom key, and custom value to create a valueRecipient tag:

There is a small issue with your feed. The value recipient types should be lnaddress rather than lightning-address: https://sessions.soapbox.pub/rss.xml . Also, the podcasting world hasn't fully figured out the switch from keysend to lnaddress. So if you want to see boost information (sender name, total unsplit amount, message, etc), you have to use keysend rather than lnaddress. I think Fountain might work regardless since it also posts this info to Nostr?

I like the way Nostrudel does it. You shouldn't need to be prompted for a signature until you're actually do something that requires a signature.
