Convert a monitoring event into mempool filter details

Let upstream systems request exactly the filters they need.

Trigger

Webhook received

Notis starts this workflow when an external tool or custom backend sends an HTTP request.

Action

Configure Mempool Filters

Tool to configure filters and abi decoding for ethereum mempool transactions. use after establishing a blocknative websocket connection to set up event filters and decoding.

Why this helps

Filter requests arrive through different systems and are hard to turn into consistent setup instructions.

  • Standardizes filter requests across tools
  • Flags missing contract or ABI data
  • Reduces setup handoff friction

Setup

Build it in a few focused steps.

  • 1Connect Blocknative in Notis once.
  • 2Create an automation for protocol monitoring requests.
  • 3Tell Notis to read the webhook payload and prepare Blocknative mempool filter and ABI decoding details from the supplied contracts, events, and chain.
  • 4Choose a Notis webhook trigger.
  • 5Select a report channel and test with one complete request.

Questions about this workflow

What if the ABI is omitted?

Notis should list it as a prerequisite instead of fabricating decoding details.

Does this create a websocket connection?

The action prepares filters for use after a Blocknative websocket connection is established.
