# /eth/v1/validator/sync\_committee\_selections

Submit sync committee selections to a DVT middleware client. It returns the threshold aggregated sync committee selection. This endpoint should be used by a validator client running as part of a distributed validator cluster, and is implemented by a distributed validator middleware client. This endpoint is used to exchange partial selection proofs (slot signatures) for combined/aggregated selection proofs to allow a validator client to correctly determine if any of its validators has been selected to perform a sync committee contribution (sync aggregation) duty in a slot. Validator clients running in a distributed validator cluster must query this endpoint at the start of each slot for all validators that are included in the current sync committee. Consensus clients need not support this endpoint and may return a 501.
