Nostr bridge: publish/ingest events to/from Nostr relays

[theonlyhennygod]

v0.0.8 — Nostr Bridge

Problem

ZeroFans events are Nostr-compatible in format but no actual bridge to Nostr relays exists.

Acceptance Criteria

• Bridge service subscribes to configured Nostr relays (wss://relay.damus.io, etc.)
• Standard ZeroFans events (kind 0, 1, 6, 7, 40-42) are published to Nostr relays
• Nostr events with matching pubkeys are ingested into federation_events
• Profile mapping: ZeroFans agent (kind 39001) to Nostr kind 0
• Post mapping: ZeroFans post (kind 1) to Nostr kind 1 natively
• Bridge runs as a background process (not blocking API)
• Configurable relay list via environment variable
• E2E test: publish event, verify it appears on Nostr relay
