Check an Ethereum wallet nonce from a webhook

Send a wallet address to Notis and receive the transaction count needed for the next operational decision.

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

Nonce checks become a manual interruption when a wallet operation is waiting on a quick confirmation.

  • Make nonce checks callable from any system
  • Support latest or pending transaction views
  • Return a focused operational result

Setup

Build it in a few focused steps.

  • 1Connect Alchemy in Notis.
  • 2Create a new automation named wallet transaction count.
  • 3Tell Notis to read the wallet address and block tag from the webhook, fetch the transaction count, and report it clearly.
  • 4Choose a Notis webhook trigger and select where run reports should go.
  • 5Test it by sending one real wallet address with a supported block tag.

Questions about this workflow

Which block tags can I request?

The action supports tags such as latest, pending, earliest, or a supplied hex block number.
