Latch.Identity (latch v0.1.0)

Copy Markdown

Resolves an atproto handle to a verified identity.

Resolution is bidirectional per the atproto identity spec, the handle is resolved to a DID and the DID document is fetched independently, and the docment's claimed handle must match the handle we started from. Neither direction alone is trusted, otherwise anyone could point DNS at a victim's DID.
