CEL enables users to submit **Encrypted Intents**, which is routed by the **Confidentiality Router** to the protocol specific **Confidentiality Adapter**, allowing private interaction with the underlying **Protocol Layer**.

The CEL consists of 4 planes:

* Intent Plane
* Routing Plane
* Adapter Plane
* Protocol Plane
