Struct ChallengeStore 

pub struct ChallengeStore { /* private fields */ }

In-memory store for pending authentication challenges.

Challenges are created during multi-step authentication (e.g., wallet signing) and consumed on the client’s response. Each challenge is one-time-use and expires after the configured TTL.
