It also verifies their validity using xID after transmission through the relayer servers, serving as the initial step of verification. {% hint style="info" %} Learn how to[ integrate the client off-chain module](/guides/getting-started/2.-implement-off-chain-module.md) on your server {% endhint %} --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
