Ways Notis can move work from Slack to Blocknative
Check gas before a transaction
When a Slack message asks whether it is a good time to send a transaction, fetch current gas estimates for a quick fee decision.
Review the next blocks' fee outlook
A Slack request for a near-term fee outlook prompts Blocknative to return base fee predictions for the next five blocks.
Get a mempool fee distribution in DM
A direct message asking about current fee trends triggers a Blocknative gas price distribution breakdown.
Find available gas oracles
When a Slack conversation asks which gas oracles are available, retrieve Blocknative's supported oracle metadata.
Check supported Blocknative chains
A Slack question about network support triggers a lookup of Blocknative's supported chain metadata.
Prepare multichain address monitoring
A Slack request to watch an account across networks prompts Blocknative to generate multichain subscription details.
Prepare a transaction hash watch
A DM containing a request to watch a transaction hash prompts Blocknative to prepare a transaction-state subscription.
Mark a transaction for monitoring
Adding a chosen reaction to a Slack message with a transaction hash prepares a Blocknative state-change subscription.
Prepare to stop a transaction watch
A Slack request to stop monitoring a transaction hash prompts Blocknative to prepare its unsubscribe details.

Four ways to start an automation.
A trigger is the event that kicks a workflow off. Notis supports four kinds: an event in a connected app, an inbound webhook, a recurring schedule, and soon, your own database.
Integration triggers
Fire when something happens inside a connected app. New Notion page, Stripe charge, Linear issue: any of 1,000+ apps can start a workflow.
Webhook triggers
A unique URL per workflow. Anything that can send an HTTP POST can start an automation, including no-code tools that speak webhooks.
Recurring triggers
Cron-style schedules run a workflow on the clock. Daily standups, hourly syncs, business-hours-only digests: the workhorse of Notis.
Database triggers
Watch a row, query, or threshold in your own database and fire the moment the data changes. Row inserted, value crosses a limit, query starts matching.
Classic automation breaks. AI adapts.
Same triggers and actions, smarter middle. AI handles the fuzziness that breaks traditional Zapier-style workflows the moment a field gets renamed.
Describe it. Notis builds it.
Skip the visual builder. Tell Notis what you want, in plain English. It writes the workflow, you review and deploy.
You · in the Notis Builder
NEW“When a row gets added to the Q4 OKRs Notion database and the status is Blocked, send a Telegram message to the owner with a summary of what's blocking, and ping me if there's no reply within 24 hours.”
