So far I‘ve got the server side of NIP-01 covered as sending, subscribing, filtering and notices.
they're probably missing a lot of info.
Oh, how clever. We could use that for the SDK. 👀
Theoretically, hear me out, hold up. 🤔
Anyone who used the NIP could adopt this as their acceptance test. Amiright?
And you could identify breaking changes with this?
Where are you writing these? On a private repo? Only found an archived cucumber repo, in your GitHub account.
