How to Add Cronos Testnet (CRO) to MetaMask in 2025

·

Adding the Cronos Testnet (CRO) to your MetaMask wallet is a straightforward process that allows developers and blockchain enthusiasts to test decentralized applications (dApps) on the Cronos network without using real funds. This guide walks you through every step—from installing MetaMask to importing test tokens—with clarity and precision.

Whether you're building smart contracts, testing DeFi protocols, or exploring cross-chain functionality, connecting to the Cronos Testnet gives you a safe sandbox environment for experimentation.

Why Use Cronos Testnet?

The Cronos Testnet is a developer-focused version of the main Cronos blockchain, designed to mirror the behavior of the live network. It enables users to:

With its Ethereum Virtual Machine (EVM) compatibility, Cronos supports tools like MetaMask, making integration seamless for Web3 developers.

Step-by-Step Guide: Connect MetaMask to Cronos Testnet

Follow these four essential steps to configure your MetaMask wallet for the Cronos Testnet.

Step 1: Install MetaMask and Create a Wallet

Before connecting to any blockchain network, you need a compatible wallet. MetaMask is one of the most widely used crypto wallets due to its ease of use and strong community support.

👉 Get started with secure Web3 access today.

To install:

  1. Open Google Chrome and go to the official MetaMask website.
  2. Click "Download", then choose "Install MetaMask for Chrome".
  3. Add the extension to your browser.
  4. After installation, click "Create a Wallet" if you’re new, or "Import Wallet" if restoring from a seed phrase.
  5. Set up a password and securely back up your 12-word recovery phrase—this is critical for account recovery.

Once completed, your wallet will default to the Ethereum Mainnet.

Step 2: Configure MetaMask for Custom Networks

By default, MetaMask only shows major networks like Ethereum and Binance Smart Chain. To interact with the Cronos Testnet, you must manually add it as a custom RPC network.

Here’s how:

  1. In your MetaMask extension, click the network dropdown at the top (e.g., "Ethereum Mainnet").
  2. Select "Add Network", then choose "Add a Network Manually".
  3. You'll now enter specific details for the Cronos Testnet.

Step 3: Enter Cronos Testnet Network Details

Fill in the following configuration settings exactly:

🔍 Note: The Chain ID and Network ID are both 338. Ensure there are no typos when entering the RPC URL.

After saving, MetaMask will switch to the Cronos Testnet. You’ll see your balance displayed in TCRO, though it will likely show zero initially.

Now you’re connected and ready to interact with Cronos-based dApps!

Step 4: Import Test CRO Tokens into Your Wallet

Since this is a test environment, you’ll need free test tokens (TCRO) to simulate transactions.

How to Get Free TCRO via Faucet

  1. Visit the official Cronos Testnet Faucet.
  2. Connect your wallet address (the one in MetaMask).
  3. Request TCRO tokens—usually limited per day to prevent abuse.
  4. Wait a few seconds; the tokens should appear in your MetaMask wallet.

If tokens don’t appear immediately:

You now have functional TCRO tokens for testing!

Frequently Asked Questions (FAQ)

Q1: What is the difference between Cronos Mainnet and Testnet?

The Cronos Mainnet is the live blockchain where real transactions occur using actual CRO tokens. The Testnet is a parallel network used for development and testing with no monetary value—ideal for debugging and learning.

Q2: Is Cronos EVM-compatible?

Yes! Cronos is fully EVM-compatible, meaning it supports Ethereum-based tools like MetaMask, Solidity smart contracts, and popular dApp frameworks like Hardhat and Truffle.

Q3: Why can’t I see my TCRO balance after using the faucet?

First, ensure you’ve selected the correct network (Cronos Testnet) in MetaMask. If balance still doesn’t show:

👉 Access powerful tools for blockchain development and testing.

Q4: Can I use hardware wallets with Cronos Testnet?

Yes—hardware wallets like Ledger or Trezor work with MetaMask and can be used on the Cronos Testnet once properly configured through the Ethereum app interface.

Q5: Are there risks in using testnets?

There are no financial risks since test tokens hold no value. However, always avoid sharing your private keys or recovery phrases—even in test environments.

Q6: How often is the Cronos Testnet updated?

The testnet is regularly updated to reflect changes planned for the mainnet. Developers should check official channels for maintenance schedules and upgrades.
