Validator

Attestation Slots

Returns all slot numbers where the specified validators were assigned attestation duties, grouped by slot. Each result shows a slot number and the count of your validators that attested in that slot. This is useful for tracking when your validators attested and identifying slots where they may have missed attestations. For example, querying one epoch with 200 validators returns up to 32 results (one per slot in the epoch) rather than 200 individual validator-slot pairs.
