# Mutable Revenue Paths

During creation of a revenue path, you may choose to create an immutable or mutable revenue path. A mutable revenue path allows the path manager to add tiers and update existing tiers in the revenue path at any time.

{% hint style="warning" %}
Mutable revenue paths require trusting the [path manager](https://docs.r3vl.xyz/reveel-protocol-v2-documentation/protocol-concepts/path-manager). The revenue distribution can be updated by the path manager.
