February 24, 2023

Why might you want to do this?

  • Notify users about new transfers to their address, e.g. creating a blockexplorer.

About Tenderly Alerts

Tenderly Alerting listens for events on the blockchain and sends real-time notifications to your desired destination when the event occurs. With Tenderly Alerting, you can stay informed about desired or undesired events related to transitions, wallets, smart contracts, or any other activity on the network.

Solution Overview

In this tutorial we’ll use a simple Express App that exposes an API webhook that can be called based on on-chain events. We will be using Tenderly, which can deliver alerts based on simple or advanced triggers from transactions and events.

This demonstrates how to setup the webhook that can deliver alerts for use cases including: balance changes, user receipts for NFT purchases, welcome messages, alerting your team of failed transactions and more.
