# Notifications: Conditions & Event Filtering (EVM & Tron)

We’ve introduced **[Notifications Conditions & Filters](/docs/notifications-conditions-and-filters)** to the Tatum Notifications system across **all supported EVM chains and Tron**. You can now define **custom conditions** that control when a webhook is triggered. This ensures you only receive notifications for **relevant events**, reducing unnecessary traffic and improving processing efficiency.

### Why it matters

* **Reduce noise:**  filter out irrelevant events before they reach your system
* **Improve performance:** process only meaningful data
* **Lower costs:** minimize webhook volume and downstream processing
