Notis

Respond to Emergencies Across All Chains Instantly

Your monitoring systems detect an issue and send a webhook. Notis spins up multichain subscriptions automatically so you're watching every network.

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

Emergency situations require immediate multichain monitoring but setting it up manually creates critical delays in incident response.

  • Respond to emergencies without setup delay
  • Monitor incidents across all networks simultaneously
  • Reduce incident response time significantly
  • Focus on resolution instead of configuration

Setup

Build it in a few focused steps.

  • 1Connect Linear and Blocknative to Notis and configure your external alert system.
  • 2Tell Notis: 'When you receive an emergency webhook, subscribe to multichain monitoring immediately.' Use chat or automation builder.
  • 3Select 'Webhook' as the trigger type and configure the webhook endpoint Notis provides.
  • 4Choose your notification channel (typically urgent channels like a dedicated incident Slack).
  • 5Test by triggering a webhook from your alert system and confirm multichain subscriptions activate.

Questions about this workflow

How do I integrate my alert system with Notis?

Notis provides a webhook URL - configure your external alerting tool to POST to that URL when incidents occur.

Which chains will be included in the emergency subscription?

All supported Blocknative chains by default, or you can customize to specific networks in the webhook data.

Will this create duplicate subscriptions if multiple alerts fire?

Blocknative deduplicates subscriptions so multiple alerts won't create redundant monitoring streams.
