Inspecting

Executing an inspection for a block will perform the following operations:

  • Retrieve traces, receipts, and block data from the RPC endpoint.
  • Decode the traces using recognized ABIs.
  • Extract structured objects such as transfers and swaps.
  • Store all these elements in the database for future querying.

Examples​

Inspect a single block​

Inspecting block 12914944:

./mev inspect 12914944

Inspect many blocks​

Inspecting blocks 12914944 to 12914954:

./mev inspect-many 12914944 12914954

Inspect all incoming blocks​

Start a block listener with:

./mev listener start

By default, it will pick up wherever you left off. If running for the first time, listener starts at the latest block.

Tail logs for the listener with:

./mev listener tail

And stop the listener with:

./mev listener stop

Backfilling​

For larger backfills, you can inspect many blocks in parallel using kubernetes

To inspect blocks 12914944 to 12915044 divided across 10 worker pods:

./mev backfill 12914944 12915044 10

You can see worker pods spin up then complete by watching the status of all pods

watch kubectl get pods

To watch the logs for a given pod, take its pod name using the above, then run:

kubectl logs -f pod/mev-inspect-backfill-abcdefg

(where mev-inspect-backfill-abcdefg is your actual pod name)
