MEV-Boost Builder Bids Archive

I’m excited to announce the release of our MEV-Boost Bids Archive!


  • All builder bids across all MEV-Boost relays
  • Data freely available under the CC-0 license
  • Uploaded nightly (at UTC 2am)
  • Data since 2024-06-03

Two files per day:

  • All bids (about 10M entries per day)
  • Top bids only (~1M entries per day)

The data is collected via three methods:

  • GetHeader polling
  • Data API polling
  • Ultrasound websocket stream

These are the collected fields:

Big thanks to @sui414 @sukoneck @Fred @facuzeta and many more for their help and support!

is there parquet support? The bidarchive link looks like it only shows

There is no Parquet support right now, and also not really planned.

We would definitely consider merging a PR if someone would create one.

For reference

  • relayscan bidarchive produces the final CSV in this bash script:
    • The way to go about adding Parquet support would probably be a standalone Golang tool/command to convert the CSV into Parquet.
  • see also the mempool dumpster Parquet support here: [1], [2]
