How to Connect Polygon Network to MetaMask

·

The Polygon network has emerged as one of the most popular Ethereum scaling solutions, empowering developers and users with faster transactions and significantly lower fees. If you're using MetaMask—a widely adopted crypto wallet for interacting with Ethereum-based dApps—you’ll likely want to connect it to the Polygon network to unlock access to a broader decentralized ecosystem.

This guide walks you through two seamless methods to connect the Polygon network to your MetaMask wallet: using Polygonscan and manual configuration. Whether you're new to Web3 or a seasoned user, this step-by-step tutorial ensures a smooth setup process.

Method 1: Connect Using Polygonscan (Recommended for Beginners)

Polygonscan is the official blockchain explorer for the Polygon network—similar to how Etherscan works for Ethereum. It simplifies network integration by allowing one-click addition of the Polygon Mainnet to MetaMask.

Step-by-Step Instructions

  1. Visit polygonscan.com
    Open the website in the same browser where your MetaMask extension is installed.
  2. Scroll to the Bottom of the Page
    Look for the section labeled “Add Polygon Network” near the footer.
  3. Click “Add Polygon Network”
    A pop-up window from MetaMask will appear with pre-filled network details.

  4. Review and Confirm the Following Details
    Ensure these values are correct before confirming:

    • Network Name: Matic Mainnet
    • New RPC URL: https://rpc-mainnet.maticvigil.com
    • Chain ID: 137
    • Currency Symbol: MATIC
    • Block Explorer URL: https://polygonscan.com
  5. Click “Save” or “Approve”
    Once confirmed, MetaMask will switch automatically to the Polygon network.

✅ You’re now connected! Your wallet is ready to interact with Polygon-based dApps.

⚠️ Note: Always verify the URL is polygonscan.com to avoid phishing scams. Never enter your seed phrase on any site.

Method 2: Manual Configuration in MetaMask

For advanced users who prefer full control, manually adding the network ensures transparency and security.

Step-by-Step Setup

  1. Open Your MetaMask Extension
    Click on the fox icon in your browser toolbar.
  2. Go to Settings > Networks > Add Network
    You can also click “Import Token” and then switch to the “Custom RPC” tab at the top.

  3. Enter the Following Network Details

    • Network Name: Polygon Mainnet (or Matic Mainnet)

    • RPC URL: Choose one of the reliable endpoints below:

      • https://rpc-mainnet.matic.network
      • https://rpc-mainnet.maticvigil.com
      • https://rpc-mainnet.matic.quiknode.pro
      • https://matic-mainnet.chainstacklabs.com
      • https://matic-mainnet-full-rpc.bwarelabs.com
    • Chain ID: 137
    • Currency Symbol (optional): MATIC
    • Block Explorer URL (optional): https://polygonscan.com
  4. Save the Network
    After entering all fields, click “Save.” MetaMask will connect to the Polygon network.

You can now send MATIC tokens, stake, trade on DEXs, or mint NFTs on Polygon.

Frequently Asked Questions

How do I switch back to Ethereum from Polygon in MetaMask?

Simply click on the network dropdown at the top of your MetaMask interface and select “Ethereum Mainnet.” This lets you toggle between chains easily depending on which dApp you're using.

Is the Polygon network the same as Matic?

Yes. The Matic Network rebranded to Polygon in 2021. While “Matic” still refers to the native token ($MATIC), the platform is now known as Polygon—a broader framework for Ethereum scaling and interoperability.

What is the correct Chain ID for Polygon?

The Chain ID for the Polygon Mainnet is 137. Always double-check this value when manually adding the network to prevent errors or security risks.

Can I use the same address on Ethereum and Polygon?

Yes! Your MetaMask address remains the same across both networks. However, assets are not automatically mirrored—you must bridge funds from Ethereum to Polygon using official bridges like the Polygon PoS Bridge.

How do I add the Mumbai Testnet to MetaMask?

To test dApps before going live, use the Mumbai testnet:

Follow the same manual steps above to add it as a custom RPC.

Why isn’t my balance showing after switching networks?

Your token balances are chain-specific. If you’ve bridged assets to Polygon but don’t see them:
