​
Update cadence

Most signals refresh within minutes. For time-sensitive threats, ChainGuard prioritizes real-time feeds and applies short cache windows so you see changes quickly.

​
Provider validation

Signals are never trusted in isolation. ChainGuard cross-checks multiple sources, down-weights stale feeds, and applies internal heuristics before a decision is surfaced.

​
Privacy considerations

Only the minimum metadata needed for enrichment is sent to providers. You should not expect any provider to receive wallet secrets or full browsing history.
