# Staking

Each Validator is responsible for verifying the batch submitted via rollup and must stake assets to participate and maintain validator status.

When a Validator operates correctly, it will automatically attempt to stake assets on the RBlock created in the current rollup contract.

{% hint style="info" %}
To initiate staking, users must manually execute the staking script provided in the Git Repository.

  {% endhint %}

If the Validator does not have the required permissions, the following error may occur. If this error appears, please contact[ **dKargo Support**](https://dkargo.io/en/about/contact) through the inquiry page.

If the Validator account does not have enough funds for staking, an error message related to insufficient tokens will be displayed. To resolve this, ensure the account used for Validator operation has sufficient ETH before running the node.
