NIP Support

Nostr is defined by its NIPs — Nostr Implementation Possibilities. Here’s where zig-nostr stands. Every “done” NIP is covered by tests, and the cryptographic ones are verified against their official specification vectors.

NIP	Title	Status
01	Basic protocol: events, signatures, subscriptions	✅ done
06	Key derivation from mnemonic seed	✅ done
09	Event deletion (ingestion)	✅ done
19	bech32-encoded entities	✅ done
21	`nostr:` URI scheme	✅ done
42	Client-to-relay authentication	✅ done
44	Encrypted payloads (v2)	✅ done
46	Nostr Connect — remote signing	✅ done
49	Private key encryption (`ncryptsec`)	✅ done
65	Relay list metadata (outbox)	✅ done
17	Private direct messages	🚧 planned (A6)
59	Gift wrap	🚧 planned (A6)
10	Reply threading	🚧 planned (A7)

The planned NIPs land with the showcase apps — a NIP-17 private messenger (A6) and a read-only outbox client (A7).
