Adding the Polygon (MATIC) network to your MetaMask wallet unlocks a faster, cheaper way to interact with decentralized applications (dApps), trade tokens, and mint NFTs. As a layer-2 scaling solution built on Ethereum, Polygon dramatically improves transaction speed and reduces gas fees—making it a favorite among Web3 users and developers.
MetaMask, one of the most widely used crypto wallets, natively supports Ethereum and its token standards like ERC-20, ERC-721, and ERC-1155. However, to access the full potential of the Polygon ecosystem, you must manually add the Polygon network to your wallet.
This guide walks you through two reliable methods to add Polygon to MetaMask, explains why it's beneficial, and answers common questions—ensuring a smooth onboarding experience into the world of scalable blockchain interactions.
Why Add Polygon Network to MetaMask?
Integrating Polygon into your MetaMask wallet opens up a range of opportunities across decentralized finance (DeFi), NFTs, and gaming. Here’s what you gain:
- ✅ Mint NFTs for free or low cost on platforms like OpenSea, especially during Polygon-based drops.
- ✅ Send and receive MATIC tokens with minimal fees and near-instant confirmation.
- ✅ Swap tokens seamlessly on Polygon-powered DEXs such as QuickSwap, SushiSwap, or Uniswap (v3 on Polygon).
- ✅ Access high-performance dApps without paying high Ethereum gas fees.
For example, during the launch of exclusive NFT collections like the Elon Punk Yacht Club, users were required to have the Polygon network added to participate in free mints. Without this setup, you'd miss out on time-sensitive opportunities in the fast-moving Web3 space.

Method 1: Add Polygon Network via Polygonscan (Desktop Only)
The easiest way to add Polygon to MetaMask is through Polygonscan, the official block explorer for the Polygon network. This method automates the configuration process and minimizes errors.
⚠️ Note: This method works only on desktop browsers with the MetaMask extension installed. For mobile users, skip to the manual method below.
Step 1: Visit the Polygonscan Website
Go to polygonscan.com, a trusted tool that lets you explore transactions, smart contracts, and wallet addresses on the Polygon blockchain.
Once loaded, scroll all the way down to the bottom of the page.
Step 2: Click “Add Polygon Network”
At the footer section of the site, you’ll see a prominent button labeled “Add Polygon Network.”
Click this button. It triggers an automatic request to your connected MetaMask wallet.
Step 3: Approve the Network in MetaMask
A pop-up will appear in your MetaMask extension asking for approval to add the network configuration.
This includes:
- Network name: Polygon Mainnet
- RPC URL:
https://polygon-rpc.com/ - Chain ID:
137 - Currency symbol: MATIC
- Block explorer:
https://polygonscan.com
Click Approve, then confirm by clicking Switch Network if prompted.
Within seconds, your wallet will switch to the Polygon Mainnet, and you’ll be ready to transact.
If you don’t see the option or encounter errors, double-check that:
- You're using the latest version of MetaMask.
- No other networks are conflicting.
- Your internet connection is stable.
Method 2: Manually Add Polygon Network (Works on Desktop & Mobile)
If you’re using the MetaMask mobile app or prefer full control over settings, adding the network manually is simple and secure.
Step 1: Open MetaMask and Select “Add Network”
On desktop:
- Click the network dropdown (usually showing “Ethereum Mainnet”).
- Choose “Add Network” at the bottom of the list.
On mobile:
- Tap your profile icon → Settings → Networks → Add Network.
Step 2: Enter Polygon Network Details
Fill in the following information carefully:
- Network Name: Polygon Mainnet
- New RPC URL: https://polygon-rpc.com
- Chain ID: 137
- Currency Symbol: MATIC
- Block Explorer URL: https://polygonscan.com
💡 Tip: Always verify these details from official sources. Entering incorrect or malicious RPC URLs can compromise your funds.
After confirming all fields are correct, tap Save (or Add on mobile).
MetaMask will validate the connection. Once successful, your wallet switches automatically to the Polygon network.
You can now view your MATIC balance and interact with Polygon-based dApps directly from your wallet.

How to Confirm Polygon Was Added Successfully
After setup, verify the integration worked:
- Check the top of your MetaMask interface—does it say “Polygon Mainnet”?
- Is there a MATIC token visible in your wallet? (You may need to import it if not shown automatically.)
- Try visiting a dApp like QuickSwap.io and see if it detects your network correctly.
If everything displays properly, you’re all set!
To switch back to Ethereum later:
- Simply click the network selector → choose Ethereum Mainnet.
No need to re-add anything; both networks stay saved in your wallet.
Frequently Asked Questions (FAQ)
Q: Can I use the same address on Ethereum and Polygon?
Yes. Your MetaMask public address remains identical across both networks. However, assets aren’t automatically transferred—you must bridge them using tools like the Polygon Bridge.
Q: Is adding Polygon safe?
Yes, as long as you enter configuration details from trusted sources like Polygonscan or official documentation. Never copy RPC URLs from unverified websites or social media posts.
Q: Why can’t I see my MATIC tokens after adding the network?
MATIC might not appear automatically. To fix this:
- Go to Assets → Import Tokens
- Paste the MATIC contract address:
0x7D1AfA7B718fb893dB30A3aBc0Cfc608AaCfeBB0 - Confirm import
Your balance should then display correctly.
Q: Do I need ETH to use Polygon?
Not directly. While Ethereum requires ETH for gas, Polygon uses MATIC as its native gas token. You’ll need MATIC to pay for transactions on the network.
Q: Can I add testnets like Mumbai?
Absolutely. Developers testing dApps can add the Mumbai Testnet using Chain ID 80001 and RPC URL https://rpc-mumbai.matic.today. Use faucets to get free test MATIC.
Q: Are there risks when switching networks?
Only if you send tokens to the wrong chain. Always double-check:
- The active network before transacting
- Whether a dApp supports Polygon
- Token addresses on both chains
Mistakes can lead to irreversible loss—so stay alert.
Final Thoughts
Adding the Polygon (MATIC) network to MetaMask is a quick but powerful upgrade for anyone exploring DeFi, NFTs, or Web3 gaming beyond Ethereum’s congested mainnet.
