Turn wallet events into nonce checks
Get a current transaction count whenever your systems raise a review event.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Get Transaction Count
This tool retrieves the number of transactions sent from a specific address (also known as the nonce). it uses the eth gettransactioncount endpoint to return the transaction count for an address at a specified block tag (latest, pending, earliest, or a hex block number), which is essential for determining the nonce for subsequent transactions.
Why this helps
Operational teams need a quick wallet activity signal without opening a block explorer.
- Respond faster to wallet review events
- Keep activity checks consistent
- Reduce manual explorer work
Setup
Build it in a few focused steps.
- 1Connect Mailchimp and Alchemy in Notis once.
- 2Create an automation named Webhook to Wallet Nonce Check.
- 3Tell Notis to retrieve the transaction count for the wallet and block tag supplied in each webhook payload, then explain the result.
- 4Choose a Notis webhook trigger and select a report channel.
- 5Test it with one real webhook payload.
Questions about this workflow
Which block tags are supported?
Use latest, pending, earliest, or a hexadecimal block number as supported by the action.
