Adding Cronos (CRO) to your MetaMask wallet opens the door to a fast, low-cost, and Ethereum-compatible blockchain ecosystem. As the native token of the Cronos Chain—a layer-1 blockchain developed by Crypto.com—CRO powers transactions, enables staking rewards, and fuels decentralized applications (dApps) across a growing DeFi landscape.
This guide walks you through the complete process of integrating the Cronos network into your MetaMask wallet. Whether you're exploring decentralized finance, trading tokens, or interacting with Web3 platforms, connecting MetaMask to Cronos ensures seamless access to one of the most scalable EVM-compatible chains.
Understanding Cronos (CRO)
Cronos is an Ethereum Virtual Machine (EVM)-powered blockchain designed to scale decentralized finance by enabling developers to easily port applications from Ethereum and other EVM-compatible networks. Built on Ethermint, it combines the speed and efficiency of the Cosmos SDK with full EVM support, allowing smart contracts and dApps to run natively on a high-performance chain.
The Cronos Chain operates in parallel with the Crypto.org Chain and leverages the Inter-Blockchain Communication (IBC) protocol for cross-chain interoperability. This means assets and data can flow securely between Cronos and other IBC-enabled blockchains.
At the heart of the network is $CRO, the native utility token. Users stake CRO to unlock benefits such as:
- Reduced trading fees on Crypto.com
- Higher interest rates on crypto deposits
- Premium features on Crypto.com’s Visa card program
- Governance participation and network security
With fast transaction finality, low gas costs, and strong developer support, Cronos has become a go-to platform for Web3 innovation.

What Is MetaMask?
MetaMask is one of the most widely used cryptocurrency wallets in the world. It functions as both a browser extension and mobile app, giving users secure access to Ethereum and EVM-compatible blockchains—including Cronos.
By connecting MetaMask to the Cronos network, you can:
- Send and receive CRO tokens
- Interact with DeFi protocols and NFT marketplaces
- Stake, swap, or bridge assets across chains
- Access decentralized apps without running a full node
Its user-friendly interface, robust security model, and deep integration with Web3 services make MetaMask an ideal choice for both beginners and advanced users.
Step-by-Step: Add Cronos to MetaMask
Follow these clear steps to configure your MetaMask wallet for the Cronos mainnet or testnet.
Step 1: Install the MetaMask Extension
First, ensure MetaMask is installed on your device. For desktop users, we recommend using the Chrome browser extension, though MetaMask also supports Firefox, Brave, and Microsoft Edge.
To install:
- Visit the official MetaMask website
- Click “Download” and select your preferred browser
- Install the extension from the browser’s web store
- Once installed, pin the extension for quick access
💡 New users: After installation, create a new wallet. You'll set a password and be given a 12-word recovery phrase. Store this phrase securely—never share it or take screenshots.
Step 2: Log In to Your MetaMask Wallet
- Click the MetaMask fox icon in your browser toolbar
- Enter your password
- Click Unlock
You’ll now see your wallet dashboard with the default Ethereum network selected.
Step 3: Add the Cronos Network
To add Cronos manually:
- In MetaMask, click the network dropdown (top center; shows “Ethereum Mainnet” by default)
- Select "Add Network"
- Choose "Add a Network Manually"
Now enter the following details depending on whether you're connecting to the mainnet or testnet.
✅ Cronos Mainnet Configuration
Network Name: Cronos
New RPC URL: https://evm-cronos.crypto.org
Chain ID: 25
Currency Symbol: CRO
Block Explorer URL: https://cronos.crypto.org/explorer/🧪 Cronos Testnet Configuration
Network Name: Cronos Testnet
RPC URL: https://cronos-testnet-3.crypto.org:8545/
Chain ID: 338
Currency Symbol: tCRO
Block Explorer URL: https://cronos.crypto.org/explorer/testnet3/After filling in all fields, click Save.
MetaMask will validate the connection. Once successful, your network selector will display Cronos, confirming the setup is complete.

Verify Your Connection
To confirm everything is working:
- Visit a Cronos-based dApp (e.g., VVS Finance or CronaSwap)
- Connect your MetaMask wallet
- Check if your CRO balance appears correctly
You can also view transaction history and token holdings via the Cronos block explorer.
Frequently Asked Questions (FAQ)
Q: Is Cronos compatible with MetaMask?
Yes. Since Cronos is EVM-compatible, it works seamlessly with MetaMask just like Ethereum, Binance Smart Chain, or Polygon.
Q: Do I need CRO tokens to use the Cronos network?
Yes. Like ETH on Ethereum, you need CRO to pay for gas fees when sending transactions or interacting with dApps on the Cronos Chain.
Q: Can I use the same MetaMask wallet for multiple networks?
Absolutely. MetaMask supports multiple EVM-compatible chains. You can switch between Ethereum, BSC, Polygon, Cronos, and others within the same wallet interface.
Q: What should I do if MetaMask shows “Invalid Chain ID”?
Double-check that all network parameters—especially Chain ID—are entered exactly as provided. A single typo can prevent connection.
Q: Where can I get testnet CRO tokens?
Visit the Cronos Faucet to request testnet CRO for development and testing purposes.
Q: Is it safe to add custom networks to MetaMask?
Yes, as long as you source network details from official websites only. Never add RPC URLs from untrusted forums or social media posts.
Final Thoughts
Integrating Cronos into MetaMask is a simple yet powerful step toward expanding your Web3 experience. With faster transactions, lower fees, and access to a vibrant ecosystem of DeFi tools and dApps, the Cronos Chain offers compelling advantages over traditional networks.
Whether you're staking CRO for rewards, trading on decentralized exchanges, or building blockchain applications, having your wallet properly configured ensures smooth and secure interactions.
As blockchain ecosystems continue to evolve, being able to navigate multiple networks—like Cronos—becomes increasingly valuable.
