# Set Up Operator Wallet

{% hint style="success" %}
If you've already imported your wallet with keys as the Xardian Operator Wallet, you don't need to assign keys or delegate again — only new wallets require delegation.
{% endhint %}

#### 1️⃣ Set Up Your Wallet

When you launch the Xardian app for the first time, a new Xardian Operator Wallet will be automatically created for you, starting with zero (0) keys. You can choose to use this wallet or connect an existing one that already holds keys. If you decide to use the Operator Wallet provided, you can skip the second step, then proceed to [assigning keys](/x-protocol-litepaper/overview/xardian-nodes/how-to-run-nodes/assign-keys-from-new-wallet.md).

{% hint style="danger" %}
**Important Reminder:** Please ensure you securely export and back up your Operator Wallet's private keys. Failing to do so may result in the permanent loss of access to your funds.
{% endhint %}

{% hint style="warning" %}
Troubleshooting: If the Xardian app doesn't generate an Operator Wallet for you, please run this command in your terminal, then reopen the app.\
\
`chmod -R 777 $HOME/.config`
{% endhint %}

#### 2️⃣ Import Your Wallet to the App

If you already have a wallet with purchased keys or want to import your existing wallet, you can do so easily. Click the 3 dots below the Xardian Wallet and select "Import Wallet". Enter your private key to import your wallet to the app. If everything goes smoothly, the app will close, and you'll need to reopen it to continue.

#### 3️⃣ Add Funds to Your Xardian Wallet

Make sure you have enough funds (Base ETH) in your Xardian Operator Wallet to keep your node running smoothly. We recommend having a minimum of 0.005 Base ETH to sign transactions and earn rewards.

#### 4️⃣ Purchase Node Keys

If you don't own any keys or want to add more, visit <https://xprotocol.org/node-sales> and connect your wallet to buy the keys you need to run your node.

That's it! Your node is now up and running. You can start enjoying the benefits of running a node. Check your rewards in the Dashboard.

## 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.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.xprotocol.org/x-protocol-litepaper/overview/xardian-nodes/how-to-run-nodes/set-up-operator-wallet.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
