  • Configure filters for a stated Ethereum mempool use case.
  • Include ABI decoding in the filter setup.
  • Keep the monitoring criteria attached to the incoming request.

  • 1Connect 2chat and Blocknative once in the Notis portal.
  • 2Create an automation in Automations, New Automation, or tell Notis what to create from any channel.
  • 3In one instruction, ask Notis to configure Blocknative mempool filters and ABI decoding for the criteria in the request.
  • 4Choose the webhook trigger and where run reports should go.
  • 5Test with one real filter request after establishing a Blocknative websocket connection.
