# MetaMask Configuration

In this guide, you will learn how to configure the [MetaMask](https://metamask.io) extension on Google Chrome to send and receive tokens, and interact with the Cronos zkEVM network.

The configuration process is similar if you are using the MetaMask mobile app.

## Create a MetaMask wallet

You need to:

* Download the [MetaMask](https://metamask.io) browser extension for desktop, or mobile app.
* And then either create a new wallet (in this case, the seed phrase will be generated by the wallet), or import an existing wallet (using the seed phrase or private key).

## Connect MetaMask to Cronos zkEVM Sepolia testnet

Let's connect your MetaMask wallet to the Cronos zkEVM network.

Click the **"My Account"** button in the top right corner. Then select **"Networks"** in the settings menu.

{% tabs %}
{% tab title="Mainnet " %}
**Name:** Cronos zkEVM Mainnet

**New RPC URL:  `https://mainnet.zkevm.cronos.org/`**

**Chain ID: 388**

**Symbol: zkCRO**

**Block explorer URL:** [**https://explorer.zkevm.cronos.org/**](https://explorer.zkevm.cronos.org/)
{% endtab %}

{% tab title="Testnet" %}
**Name:** Cronos zkEVM Sepolia Testnet

**New RPC URL:**  `https://testnet.zkevm.cronos.org/`

**Chain ID: 240**

**Symbol: zkTCRO**

**Block explorer URL:** [**https://explorer.zkevm.cronos.org/testnet/**](https://explorer.zkevm.cronos.org/testnet/)
{% endtab %}
{% endtabs %}

After saving the network configuration, we should be able to see your token balance.&#x20;

## Connect MetaMask to Ethereum Sepolia testnet

If you need to execute cross-chain transactions between Cronos zkEVM testnet and Ethereum testnet, you definitely need to configure the Ethereum Sepolia testnet too.

Open MetaMask and click on the network icon:

Then, simply toggle "Show test networks" and click on Sepolia to activate the Ethereum Sepolia testnet network:
