Prepare a multichain watch from Ably

When a transaction or address is shared through Ably, prepare the multichain subscription details without manually rebuilding the context.

Trigger

Webhook received

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

Action

Subscribe Multichain

Tool to generate websocket subscription details for events across multiple chains. use when preparing to track a transaction hash or account address across chains via blocknative multichain sdk.

Why this helps

A transaction or address mentioned in one channel may need attention across several networks, making manual monitoring easy to forget.

  • Use transaction or address context from an Ably webhook.
  • Prepare multichain subscription details for the supplied chain context.
  • Keep the resulting details and any missing chain information in one run report.

Setup

Build it in a few focused steps.

  • 1Connect Ably and Blocknative once in the Notis portal.
  • 2Create an automation in Automations, then New Automation, and give it a clear name.
  • 3Tell Notis to extract the transaction hash or account address and supplied chain identifiers from each webhook, then prepare Blocknative multichain subscription details.
  • 4Choose the webhook trigger and a report destination. Configure Ably to send the relevant message to the Notis webhook.
  • 5Test with one real address or transaction hash and confirm the report reflects the supplied chain context.

Questions about this workflow

Can this workflow infer which chains I want?

It can use chain context supplied in the webhook. Include the networks you intend to monitor; the workflow should report when that information is missing.

Does preparing the details start a live websocket subscription?

The action generates subscription details for the Blocknative multichain SDK. A compatible websocket setup is needed to use those details for live events.

Can I use an account address instead of a transaction hash?

Yes. The multichain action supports preparing subscription details for an account address or transaction hash across supplied chains.
