Key notary — showcase
MF Keys
MXKeys is the Matrix federation key notary of the ecosystem. It runs as a separate product on its own host; this page is a description and pointer only — no keys or API are served here.

What the notary does
- Resolves a target homeserver via
.well-known, SRV, explicit host:port or IP literal. - Fetches
/_matrix/key/v2/server, enforces canonical JSON and verifies each Ed25519 self-signature. - Adds the notary's perspective signature and caches the verified response in PostgreSQL and memory.
- Minimal default surface; transparency, analytics, trust policy and clustering are opt-in modules.
The notary API and the Matrix server_name stay on mxkeys.org. This subdomain never serves keys or an API.
