## Content

About LayerZero LayerZero is a User Application (UA) configurable on-chain endpoint that runs a ULN. It relies on two parties to transfer messages between on-chain endpoints: the Oracle and the Relayer. When a UA sends a message from chain A to chain B, the message is routed through the endpoint on chain A. The endpoint then notifies the UA specified on chain B that a message has been received.
