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 range.evaluation_window). Omit range to use it.
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.
Authorizations
Body
Free selectors available to all users:
- validator_identifiers: One or more validator indices or public keys to filter by.
- dashboard_id: Your beaconcha.in dashboard ID (requires a free account).
Premium selectors for Scale & Enterprise plans (https://beaconcha.in/pricing):
- withdrawal: The validator's withdrawal credential or the Ethereum wallet address used for withdrawals.
- deposit_address: The Ethereum wallet address used for the validator's deposit.
- entity: The name of the assigned entity (e.g., "Lido", "Coinbase"). Optionally include
sub_entityfor more specific filtering. Matching is case-sensitive.
Note: The set of validators matched by deposit_address and withdrawal selectors is updated once per epoch (~6.4 minutes). Newly deposited validators may take up to one epoch to appear in query results.
Note: The set of validators matched by entity selector is updated once per day.
