Notis

Close out multichain monitoring from your process

When a tracking task is done, make cleanup part of the process that closes it out.

Trigger

Webhook received

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

Action

Unsubscribe Multichain

Tool to unsubscribe from events across multiple chains using the multichain sdk. use after stopping monitoring of an address or transaction to clean up resources, e.g., call: blocknative.unsubscribe({ id: '0x..', chainid: '0x1' }).

Why this helps

Monitoring can continue after a task is complete when stopping the subscription depends on someone remembering a separate cleanup step.

  • Prepare multichain unsubscribe details when tracking ends
  • Tie cleanup to an HTTP initiated process
  • Reduce forgotten monitoring cleanup

Setup

Build it in a few focused steps.

  • 1Connect Blocknative once in the Notis portal.
  • 2Create an automation in the portal or tell Notis in plain language to create one.
  • 3Describe the outcome in one instruction and specify the transaction or address identifier and chain IDs to unsubscribe.
  • 4Pick a webhook trigger and choose where run reports should go.
  • 5Test with one real HTTP request for a monitoring task that has ended.

Questions about this workflow

What information does the unsubscribe need?

Specify the identifier and chain IDs in the request or instruction so the multichain unsubscribe can be prepared for the correct subscriptions.

Does this stop monitoring for an Ethereum hash only?

This action handles unsubscribing across multiple chains using the multichain SDK. A separate action is available for a single Ethereum transaction hash.
