How to Add Cronos to MetaMask: An In-Depth Walkthrough for Beginners
MetaMask has cemented itself as one of the most popular and user-friendly crypto wallets available today. Its multi-chain compatibility makes MetaMask an extremely versatile wallet to store and transact with a vast array of both mainstream cryptocurrencies as well as tokens on emerging networks.
One such network that has been integrated into MetaMask is Cronos – a decentralized, EVM-compatible smart contract blockchain that aims to drive global adoption of decentralized finance.
This step-by-step guide will show you how to get set up to access Cronos DApps and tokens using MetaMask. Follow along to get connected in just minutes!
A Primer on Cronos
Before diving into the MetaMask setup, let‘s do a quick rundown of some key things you should know about the Cronos blockchain network:
Built for Speed and Scalability
Cronos is optimized for fast and inexpensive transactions, making it ideal for DeFi applications. It achieves throughput of up to 10,000 TPS with sub-second finality, significantly outpacing networks like Ethereum.
Cronos achieves up to 10,000 TPS – far greater than Ethereum‘s 15 TPS
By leveraging the latest blockchain innovations around Proof-of-Stake and parallel processing, Cronos is able to scale efficiently. Fees are also extremely low – a standard token transfer on Cronos costs just a few cents.
Interoperability
A key feature of Cronos is cross-chain interoperability and multi-chain asset transfers. This allows cryptocurrencies from chains like Bitcoin and Ethereum to be bridged over to Cronos.
Once ported to Cronos as wrapped tokens (e.g. wcBTC, wETH), they can be used across the various DeFi and dApp ecosystem being built on Cronos.
Rapid Growth
Since launching in 2021, Cronos adoption and development activity has seen massive growth:
- Over $3 billion TVL (Total Value Locked) in DeFi protocols
- 430+ dApps and counting
- 1.5+ million wallet addresses

Clearly there is tremendous developer and user interest in building out the DeFi ecosystem on Cronos.
What is MetaMask?
For those new to the world of Ethereum and dApps, MetaMask serves as the gateway crypto wallet to seamlessly and securely interact with decentralized applications.
Key features:
- Store, send, and receive ETH & ERC20 tokens
- Access dApps, DeFi platforms and NFT marketplaces
- Create and manage multiple accounts and identities
- Connect hardware wallets (Trezor, Ledger etc.)
- Customizable gas fees for transactions
As a non-custodial wallet, users have complete control of their private keys in MetaMask. Your secret 12-word phrase essentially IS your wallet, giving you full ownership.
In 2022, MetaMask surpassed a remarkable milestone of over 30 million monthly active users making it the crypto wallet tool with the highest adoption globally.
Step-by-Step Guide to Add Cronos to MetaMask
Without further ado, let‘s get Cronos added to your MetaMask wallet:
Access MetaMask
First, open the MetaMask browser extension or mobile app on your device. You‘ll need to login to your wallet first.
If you haven‘t created a wallet yet, be sure to set a strong password and carefully store the seed phrase during initial setup.
Navigate to Networks Menu
Click on the network name next to your account name (it will likely show Ethereum Mainnet or another network you have connected).
In the dropdown menu, select ‘Custom RPC‘ at the bottom.
Accessing Custom RPC menu in MetaMask
Enter Cronos Network Details
Under the "New RPC URL" field:
- Enter network name:
Cronos - Enter the RPC URL endpoint:
https://evm.cronos.org/ - Enter chain ID:
25 - Enter symbol:
CRO - Enter Explorer URL:
https://cronos.crypto.org/explorer/
Configuring Cronos network details in MetaMask‘s "Add Network" menu
Then click ‘Save‘ and voila! Cronos will now show as one of your connected networks.
Switch Between Networks
To toggle between Ethereum, Cronos or other configured chains, simply select the desired network from the menu. This lets you easily access dApps and tokens specific to any particular chain.
For Cronos, you‘ll have access to popular DeFi platforms like VVS Finance, DEXs like CronaSwap as well as governance/staking portal Crypto.org DeFi Wallet.
Plus you can store, send or receive CRO utility tokens across the Cronos network.
Import Tokens
If you want to import custom Cronos tokens that don‘t auto-populate, simply go into ‘Import Tokens‘ menu, enter the contract address of token and it will show up in your wallet.
You‘ll need some CRO tokens to pay for gas fees for transactions and interactions with DApps. You can purchase CRO from supported exchanges like Crypto.com or Gate.io if you don‘t already have it in your wallet.
Now comes the fun part…
Using Cronos DeFi Apps with MetaMask
Here‘s a quick overview of just some of things you can explore on Cronos using MetaMask:
Yield Farming with VVS
VVS Finance is the top yield optimizer on Cronos offering insane APYs through liquidity pools.
You can stake stablecoin LPs like CRO-USDC to earn yields between 50-90% APY!
I‘d recommend starting off small as impermanent loss can eat away at profits during high volatility.
Access NFT Marketplaces
NFT collectors now have a vibrant new marketplace to explore with Crypto.com NFT built natively on Cronos chain. No need for gas-guzzling Ethereum network fees here.
MetaMask works seamlessly with Crypto.com NFT allowing users to purchase NFT collectibles and digital art using CRO tokens.
Swap Tokens on DEXs
MetaMask enables you to easily trade between tokens on Cronos-based DEX platforms like Cronaswap, Crodex and more.
Take your token swapping game to the next level by leveraging Yield Aggregators like Beefy Finance as well.
Bridge Crypto Assets from Other Chains
Leverage cross-chain bridges like Crypto.org Bridge or Ethereum Bridge to port tokens from other networks over to Cronos. This opens up a whole new array of DeFi opportunities to maximize earning potential and capital efficiency.
As you can see, connecting MetaMask gives you virtually endless possibilities now that you have the power of Cronos‘s thriving ecosystem.
Pros of Using Cronos Network & MetaMask
Now that you‘re all set up, let‘s recap some of the major benefits this potent combo unlocks for you from a user perspective:
For Cronos:
✅ Negliable fees – transaction costs are fractions of a penny
✅ Speed – can support upto 10,000 TPS for fast finality
✅ Interoperability – bridge external crypto assets into ecosystem
✅ High APY incentives via DeFi platforms like VVS

✅ Open source approach facilitates innovation
✅ Highest user base providing network effects
As you can see, both tools have carved out very compelling value propositions for users which work extremely powerfully in tandem.
Ensuring Wallet Security
Of course, anytime you add integrations and connectors, it potentially widens the attack surface area. Make sure you follow security best practices:
🔐 Use a strong password and enable 2FA
🔒 Carefully safeguard your seed phrase – literally don‘t take a photo or even screen grab!
🔑 Beware of phishing attempts and fake URLs
⚠️ Be vigilant of suspicious smart contracts seeking overreaching permissions
Additionally, because MetaMask functions as a portal to applications, be sure to only access legitimate dApps vetted by a credible community like Crypto.com‘s dApp listing.
Frequently Asked Questions
Here are answers to some commonly asked questions:
Does adding Cronos compromise my existing wallet security?
No, MetaMask keeps your key management isolated from networks. Each network effectively gets isolated permission to only its own domain. Just don‘t ever reveal seed phrase.
Do I need to create a separate MetaMask account for Cronos?
No, you can use the same wallet address. Adding Cronos just appends another network that can accessed independently.
How much does it cost to use Cronos or MetaMask?
MetaMask is 100% free. Cronos itself charges a fraction of a cent for basic transactions. However certain complex smart contract interactions might be slightly pricier.
What happens if I send BTC or ETH directly to my MetaMask address?
Don‘t do this! MetaMask addresses are designed for EVM network chains like Ethereum or Cronos. Other chains must have tokens bridged over using appropriate bridge mechanism for each token.
What if I have issues connecting Cronos or finding specific tokens?
Be sure to check for any network outages on Cronos status site Cronos Status. Also feel free to reach out to MetaMask‘s excellent support community on Discord.
So there you have it! By now you should be well on your way to exploring all that Cronos can offer through the smooth convenience of MetaMask as your Web3 wallet.
Here‘s to the future of decentralized finance – it starts with you!
