# Web3 wallets

We recommend using MetaMask. It is the industry standard Web3 wallet and is available as both a browser extension and a mobile app. You will need to [download MetaMask](https://metamask.io) and install it on your preferred device. Then, create a MetaMask account.

{% hint style="danger" %}
Most Web3 wallets which are compromised happen when installing. Users either have malware on their device or click a fake link to download a wallet that looks like the official one. PLEASE be careful.

Remember to keep your Seed Phrase safe as this is the ONLY way to recover your wallet.
{% endhint %}

### Setting up the Polygon blockchain

Note: Before starting, ensure that you have the MetaMask extension installed in your web browser. If you don't have it, you can download it from the [official MetaMask website](https://metamask.io) and set up an account.

If you're setting up MetaMask for the first time, you'll need to create a new wallet. Follow the instructions to set up a password and save the recovery seed phrase in a secure location. If you already have a MetaMask wallet, you can import it using your existing seed phrase or private key

Step 1: Open MetaMask Click on the MetaMask extension icon in your browser's toolbar to open the MetaMask wallet interface.

Step 2: Scroll down the network list and click "Add network" at the bottom.

### Wallet Connect&#x20;

Once MetaMask is installed, click on the gold icon in the navigation bar's top-right corner. A prompt will appear, requesting you to connect your wallet to the game.
