Clean up multichain monitoring after a subscription event

Keep monitoring tidy by pairing a research change with an explicit cleanup action.

Trigger

New YouTube Channel Subscription

Triggers when a new channel is subscribed.

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

Old address or transaction subscriptions can remain active after your focus changes.

  • Reduce stale subscriptions
  • Make cleanup event driven
  • Keep monitoring scope intentional

Setup

Build it in a few focused steps.

  • 1Connect YouTube and Blocknative once.
  • 2Create the automation and provide the multichain subscription target to remove.
  • 3Choose New YouTube Channel Subscription as the trigger.
  • 4Select a report destination and test with one subscription event.

Questions about this workflow

What target is removed?

The prompt must identify the existing multichain subscription target, such as an id and chain context.

Will the YouTube subscription itself be changed?

No. The action only prepares the Blocknative unsubscribe operation.
