๐ MEV Bids
Returns the full per-relay bid ladder for a single blockโs slot โ every recorded relay bid with its value, arrival time, relay, builder, and source. Intended for research and auditing.
Results are ordered by arrival time and paginated. An optional slot_offset_ms_range filters bids by their slot offset.
Note: MEV relay and timing data is only available on mainnet at this time.
History: Relay bid collection began on 2024-06-03 (UTC). No bids are recorded for slots before that date โ including all pre-Merge blocks โ so the bid ladder is empty for them.
Data freshness: per-slot relay statistics lag the chain head by roughly 4 hours.
Premium Endpoint: This endpoint requires a Scale or Enterprise plan.
