Catch Urgent Transactions as They Appear in the Mempool
Your team flags urgent transactions in Linear comments. Notis sets up mempool monitoring automatically so nothing slips through.
Trigger
Comment Received Trigger
Triggered when a comment is received.
Action
Configure Mempool Filters
Tool to configure filters and abi decoding for ethereum mempool transactions. use after establishing a blocknative websocket connection to set up event filters and decoding.
Why this helps
Critical transactions get called out in comments but you have to manually log into Blocknative to set up filters, risking missed alerts during context-switching.
- Filter high-priority transactions automatically
- Stop losing urgency context when switching tools
- Catch transactions before they confirm
- Keep your team in the loop without extra steps
Setup
Build it in a few focused steps.
- 1Connect Linear and Blocknative integrations in the Notis portal (once).
- 2Tell Notis: 'When someone comments on a Linear issue with urgent flags, configure mempool filters to monitor those transaction patterns.' Use chat or automation builder.
- 3Select 'Comment Received' as your trigger and pick Slack or your preferred notification channel.
- 4Test by posting a comment like 'Urgent: watch for transfers from 0x...' and verify Blocknative starts filtering.
- 5Team members can now flag transactions in comments and mempool monitoring activates automatically.
Questions about this workflow
What transaction patterns can I filter on?
Notis recognizes hex addresses, contract names, function signatures, and keywords like 'urgent' or 'high-priority' in comments.
Will this interfere with existing mempool filters?
No - Blocknative layers new filters without removing existing ones, so your monitoring grows as needs emerge.
Can I set different filter rules for different teams?
Yes - create separate automations with different comment trigger phrases, e.g., 'urgent:' for critical and 'monitor:' for standard watching.
