Nostr

#[0] I’ve just implemented a zapper on top of LND, and it seems to be producing valid zaps, but they’re not appearing in Damus.

I’m probably missing something, would you mind taking a look?

E.g. I’ve zapped this note: nostr:note1v9qhyek3n6z59qnffunqut0lj0awafaerqk0ghzymy4dejgtnhws5pts8r

Iris seems to show it as zapped 🤔

The event ID of the zap is: 7ce9d7a054d3e1464b27b7f2d8fadd277b58ca0e80fa3638f02f78f590913f8e

Oh! I have a feeling it’s using the base64 preimage, not the hex encoded version!

It doesn’t check preimage. Just make sure rhe 9735 pubkey matches the nostrPubkey on the lnurl endpoint. It also checks description hash

The public key definitely matches.

I expect it’s to do with the description hash then, as I’m probably not serialising the event properly.

Thanks! 🤙🏻

That was totally it, it’s working now!

Thanks for the reference implementation (cln-nostr-zapper) and the detailed NIP, it made it reasonably straightforward to implement 🙇
