Prepare multichain cleanup after unsubscribe

When someone leaves, stop watching their activity across every relevant chain. Notis prepares the multichain cleanup handoff.

Trigger

Unsubscribe Trigger

Triggered when a subscriber unsubscribes from Mailchimp

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

Cross-chain monitoring creates several cleanup points, so one forgotten subscription can keep producing noise after offboarding.

  • Coordinate cleanup across chains
  • Reduce stale monitoring noise
  • Make offboarding repeatable

Setup

Build it in a few focused steps.

  • 1Connect Mailchimp and Blocknative once in Notis.
  • 2Create an automation for multichain unsubscribe cleanup.
  • 3Tell Notis to prepare Blocknative multichain unsubscription details after an unsubscribe using the address, transaction, and chain context you provide.
  • 4Select the Unsubscribe Trigger, choose a report channel, and test with one real event.

Questions about this workflow

Can this handle an address and a transaction?

Yes. Include the identifier type and chain details in the instruction to Notis.

Does it unsubscribe from Mailchimp?

No. The Mailchimp event is the trigger, and the action prepares Blocknative monitoring cleanup.
