The Polygon network, formerly known as the MATIC network, is a leading layer-2 decentralized scaling solution for the Ethereum blockchain. It enables developers to build scalable, user-friendly decentralized applications (dApps) with low transaction fees while maintaining high speed and robust security. By leveraging Ethereum's underlying security, Polygon offers an optimized environment for blockchain operations.
Metamask stands as the most widely-used open-source, non-custodial wallet in the cryptocurrency ecosystem. It allows millions of users across various operating systems to securely purchase, store, and trade digital assets with ease. Since Polygon is an Ethereum sidechain and compatible with the Ethereum Virtual Machine (EVM), it can be seamlessly integrated into Metamask using custom RPC configurations.
This guide provides clear, step-by-step instructions to add the Polygon network to your Metamask wallet on both desktop and mobile platforms.
Why Use Polygon Network?
Polygon addresses some of the most pressing challenges faced by the Ethereum mainnet, such as high gas fees and network congestion. It supports a thriving ecosystem of dApps, decentralized finance (DeFi) protocols, and non-fungible token (NFT) marketplaces.
By adding Polygon to your Metamask, you gain access to faster and cheaper transactions while interacting with the expansive world of Ethereum-compatible applications.
How To Add Polygon To Metamask (Quick Steps)
- Open the Metamask extension or mobile app and unlock your account.
- Click on the network selection dropdown.
- Choose the option to Add Network.
- Input the correct RPC details for the Polygon Mainnet.
- Save the new network settings.
- Transfer MATIC tokens to your newly configured wallet.
Detailed Guide To Adding Polygon Network On Desktop
Step 1: Unlock Your Metamask Wallet
Begin by launching the Metamask extension in your web browser. If you haven’t installed it yet, you can download the official extension from the Metamask website. Enter your password to unlock your wallet and access its main interface.
Step 2: Access The Network Menu
On the Metamask main window, locate and click on the network dropdown menu. This typically displays the currently active network, such as "Ethereum Mainnet."
Step 3: Initiate Adding A New Network
From the dropdown menu, select the Add Network button. This will open a new form where you can input the custom RPC details required to connect to the Polygon blockchain.
Step 4: Enter Polygon Mainnet RPC Details
Carefully enter the following information into the corresponding fields:
- Network Name: Polygon Mainnet
- New RPC URL: https://polygon-rpc.com/
- Chain ID: 137
- Currency Symbol: MATIC
- Block Explorer URL: https://polygonscan.com/
After verifying that all details are correct, click Save. The Polygon network will now be added and set as your default network. You can always switch back to other networks using the same dropdown menu.
How To Add Polygon On Metamask Mobile App
The process on mobile is more streamlined, as the Metamask app includes a list of popular pre-configured networks.
Step 1: Open The Metamask App
Launch the Metamask application on your iOS or Android device and unlock it using your password or enabled biometric authentication.
Step 2: Navigate To Settings
Tap on the menu icon (usually three lines) in the top-left corner of the app's dashboard. From the side menu that appears, select Settings.
Step 3: Select The Networks Menu
Inside the Settings menu, find and tap on Networks. This will show you all the blockchain networks currently available in your wallet.
Step 4: Add A New Network
Tap on Add Network to view a list of available blockchains. Select the Popular tab to quickly find pre-configured options.
Step 5: Choose And Approve Polygon Mainnet
Scroll through the list and tap on Polygon Mainnet. Review the network details and then tap Approve to add it to your wallet. The app will automatically switch to the Polygon network.
How To Transfer MATIC To Your Metamask Wallet
To interact with the Polygon network, you need its native token, MATIC, to pay for transaction fees (gas). You can acquire MATIC on a major cryptocurrency exchange and withdraw it to your Metamask wallet address.
- Acquire MATIC: Purchase MATIC tokens on a supported exchange.
- Copy Your Address: In your Metamask wallet, ensure the Polygon network is selected and copy your public wallet address.
- Initiate Withdrawal: On the exchange, navigate to the withdrawal section, select MATIC, and choose the Polygon network.
- Paste Address and Send: Paste your Metamask address, enter the amount, and confirm the withdrawal. Always double-check the address and network to avoid loss of funds.
Transactions on the Polygon network are usually confirmed within minutes. You can 👉 explore more strategies for managing gas fees and tracking your transaction on the Polygonscan block explorer.
Adding Wrapped Ethereum (WETH) To Polygon on Metamask
While ETH itself is not native to Polygon, you can use Wrapped Ether (WETH), an ERC-20 token pegged 1:1 to the value of ETH. This allows you to use Ethereum's value within the Polygon ecosystem.
- Get the Contract Address: The contract address for WETH on Polygon is
0x7ceB23fD6bC0adD59E62ac25578270cFf1b9f619. - Import the Token: In your Metamask wallet with the Polygon network active, click Import tokens. Paste the WETH contract address into the field; Token Symbol and Decimals should auto-populate.
- Complete Import: Click Add Custom Token and then Import Tokens. Your WETH balance will now be visible in your asset list.
Frequently Asked Questions
Is Polygon the same as MATIC?
Polygon is the broader network platform, originally known as the Matic Network. MATIC is the name of its native cryptocurrency token used for staking, governance, and paying transaction fees on the network.
Why do I need to add Polygon as a custom network?
Metamask does not include every blockchain by default. Adding Polygon via its custom RPC details allows your wallet to correctly communicate with the Polygon blockchain, enabling you to see balances and conduct transactions.
Can I use the same address for Ethereum and Polygon on Metamask?
Yes. Because Polygon is an EVM-compatible sidechain, your Metamask Ethereum address is the same on both networks. However, assets exist on their respective chains, so ETH on Ethereum Mainnet is separate from MATIC or WETH on the Polygon network.
What if my MATIC tokens don’t appear after transferring?
First, ensure you selected the Polygon network during the withdrawal from the exchange. Then, check the transaction status on Polygonscan.com using your wallet address. If confirmed on-chain, try refreshing your Metamask asset list.
Is it safe to add custom RPC networks?
It is safe as long as you use the correct, official RPC details from a trusted source. Using incorrect information could lead to lost funds. Always verify the details from the project's official documentation.
Do I need ETH to pay for gas on Polygon?
No. Gas fees on the Polygon network are paid in its native token, MATIC. You do not need Ethereum (ETH) to perform transactions on Polygon.
Final Thoughts
Integrating the Polygon network with your Metamask wallet unlocks a powerful and efficient layer-2 ecosystem. The process is straightforward, whether you are using a desktop browser or a mobile device. By following the detailed steps for adding the custom RPC and transferring MATIC tokens, you can seamlessly start exploring decentralized applications with lower fees and faster speeds.
