nutzap and zap (in)compatibility

[alltheseas]

problem statement

@alexgleason raised a point in examination of nutzaps, these are not compatible with zap-zaps

So we looked into adding nutzaps to Ditto. The biggest problem is that it's not backwards compatible with regular zaps. And almost nobody implements it. Even though a lot of people talk about it. So it's a chicken and egg problem. Primal needs to implement it first, then it will be worth everyone else adding.

open questions

Besides advocacy, convincing most popular app(s) to adopt standard XYZ, is there a way to make nutzaps and zaps interoperable?

You can send NIP-57 zaps FROM a NIP-60 wallet.

Is it possible to amend NIP-57 to allow zaps from NIP-57 to NIP-60 wallets? Does this make sense?

@alltheseas I think it's possible for nutzap users to join a service, similar to nip05, which will enable them to enter their cashu wallet information and get a normal lightning address. I don't think anybody has done this yet.

EDIT: I discovered this after making my original post.

This is great, as it does not require modification of NIPs, and asking dozens of clients to update their implementations.

If from the end user perspective all of this is automated under the hood of the cashu wallet, then the challenge of onboarding and user friction is eliminated.

for reference, here is an example user story "auto-generate LN wallet for users onboarding to Damus" https://github.com/damus-io/damus/issues/1623

I don't even know where to begin here
