Check gas prices before a deal-related transaction
Before sending a transaction tied to an Affinity deal, ask Notis for current Blocknative gas estimates for the inclusion probabilities you care about.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Get Gas Prices
Retrieves gas price estimates for likely transaction inclusion.
Why this helps
Checking gas estimates separately from fundraising work adds a small but easy-to-forget step before a transaction.
- Get gas estimates for selected inclusion probabilities.
- Bring the fee check into a deal-related workflow.
- Avoid relying on an old estimate when planning a transaction.
Setup
Build it in a few focused steps.
- 1Connect Affinity and Blocknative once in the Notis portal.
- 2Create an automation in Automations, New Automation, and name it.
- 3In one instruction, ask Notis to retrieve Blocknative gas prices for the supplied chain and inclusion probabilities, then summarize them for the deal context.
- 4Choose a webhook trigger and select where run reports should go.
- 5Test with a real planned transaction and the desired inclusion probabilities.
Questions about this workflow
Does this action send or submit the transaction?
No. It retrieves gas price estimates for specified inclusion probabilities.
What should I include in the webhook request?
Provide the relevant chain and the inclusion probabilities you want estimates for.
Are estimates guaranteed to match the eventual transaction fee?
No. The action fetches estimates for the next block or approximately the next 10 seconds, so values can change.
