# 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.
