MEV Timing Aggregate

Returns the overall MEV timing posture and histogram for a set of validators over a fixed evaluation window. The validator set may be selected by identifiers, dashboard, withdrawal/deposit address, or entity/sub-entity.

Use case guide: Compare MEV Timing shows how to profile validator cohorts and interpret their timing distribution.

Protocol caveat: The 1200 ms and 2600 ms timing bands apply to pre-Glamsterdam slots. Glamsterdam introduces ePBS and restructures slot production, so post-fork classifications may change.

Data provenance: Timing statistics are derived from offchain relay APIs and streams. Relay-reported timestamps, identities, and bid coverage are not independently verifiable from onchain data; coverage gaps or inconsistent reporting can affect results.

Currently only the 180d rolling window is available (see evaluation_window).

Note: MEV relay and timing data is only available on mainnet at this time.

History: Relay bid collection began on 2024-06-03 (UTC). The evaluation window only reflects data from that date onward.

Data freshness: validator timing profiles are rebuilt nightly over a rolling 180-day window.
