**7. How long does it take to receive funds after unstaking esMOZ?**

Instant.

**8. How long does it take to receive funds after undelegating license?**

Instant.

**9. Do I need to stake esMOZ to run a node independently?**

You can run a node without staking esMOZ, but a minimum of 10,000 esMOZ staked per node is required to qualify for rewards.

**10. Does running the reward-claimer command once enable automatic reward claims?**

Once executed, it will run in the background but requires the terminal to remain open.

* Please check if you have completed the steps for [running the node and claiming rewards](https://docs.lumoz.org/verifier/setup-verifier-node/setup-node/build-your-own/2.-run-the-node) after the node initialization.
* Please check do you have enough MOZ in your operator wallet.
* Please check if your CLI client running well.
* Please check if your node tier have been Bronze (10000 staked esMOZ at least).
