Events from the execution layer p2p network

  • Public Parquet Files

Tables

mempool_transaction

Each row represents a transaction that was seen in the mempool by a sentry client. Sentries can report the same transaction multiple times if it has been long enough since the last report.

Availability

Data is partitioned daily on event_date_time for the following networks:

  • mainnet: 2023-07-22 to 2024-11-30
  • holesky: 2024-01-08 to 2024-11-30
  • sepolia: 2024-01-08 to 2024-11-30
