Connecting the Polygon network to your MetaMask wallet opens the door to faster, lower-cost transactions and seamless interaction with decentralized applications (DApps). As one of the most popular Ethereum Layer 2 scaling solutions, Polygon enhances blockchain efficiency while maintaining compatibility with the Ethereum Virtual Machine (EVM). This guide walks you through two reliable methods to add Polygon to MetaMask—quickly via Polygonscan or manually—so you can begin exploring DeFi, NFTs, and more with minimal gas fees.
Whether you're using MetaMask on desktop or mobile, this process is straightforward and secure when done correctly. Let’s dive in.
Why Connect Polygon to MetaMask?
Before we get into the setup, it’s important to understand why integrating Polygon with MetaMask is valuable:
- Low transaction fees: Polygon drastically reduces gas costs compared to Ethereum mainnet.
- High-speed transactions: With support for up to 65,000 transactions per second, it's ideal for active traders and DApp users.
- EVM compatibility: Most Ethereum-based tools, wallets, and DApps work seamlessly on Polygon.
- Access to DeFi and NFTs: Use platforms like Aave, QuickSwap, and OpenSea (Polygon version) with ease.

Method 1: Add Polygon Network Using Polygonscan (Desktop Only)
This method is the fastest way to connect MetaMask to Polygon—but only works on desktop browsers.
Step 1: Visit Polygonscan
Go to polygonscan.com, a blockchain explorer for the Polygon network. Scroll all the way down to the bottom of the homepage.
Step 2: Click “Add Polygon Network”
At the footer of the page, you’ll see a button labeled Add Polygon Network. Click it.
This action triggers a request that automatically sends the correct network parameters to your MetaMask extension.
Step 3: Approve in MetaMask
A pop-up will appear in your MetaMask wallet asking for approval to add the network. Review the details (name, RPC URL, chain ID), then click Approve.
Once approved, MetaMask will switch to the Polygon Mainnet, and you’re ready to go.
⚠️ Note: This method does not work on the MetaMask mobile app due to browser limitations.
Method 2: Manually Add Polygon Network to MetaMask
Use this method if you're on mobile or prefer full control over the configuration.
Step 1: Install and Set Up MetaMask
If you haven’t already, download MetaMask from the official site as a browser extension (Chrome, Firefox, Brave, Edge) or install the app on iOS/Android.
During setup:
- Choose Create a Wallet or Import Wallet.
- Create a strong password.
- Securely back up your 12-word recovery phrase. Never share it or store it online.
After setup, MetaMask defaults to the Ethereum network.
👉 Secure your digital assets with best-in-class wallet practices.
Step 2: Access Network Settings
In your MetaMask extension:
- Click the network dropdown (usually shows "Ethereum Mainnet").
- Select Add Network.
- Choose Add a Network Manually.
Step 3: Enter Polygon Network Details
Fill in the following information exactly:
- Network Name: Polygon Mainnet
- New RPC URL:
https://polygon-rpc.com - Chain ID:
137 - Currency Symbol: MATIC
- Block Explorer URL:
https://polygonscan.com(optional)
Click Save. MetaMask will validate and add the network.
You should now see “Polygon Mainnet” in the network selector. Your wallet is connected!
How to Add Custom Tokens on Polygon via MetaMask
Once connected, you might want to view tokens not automatically displayed in your wallet.
Step 1: Find the Token Contract Address
Visit Polygonscan and search for the token (e.g., USDC, QUICK). Copy its contract address.
If unavailable on Polygonscan, check Etherscan or the project’s official website.
Step 2: Import into MetaMask
- In MetaMask, go to the Assets tab.
- Click Import Tokens.
- Switch to Custom Token.
- Paste the contract address.
- Ensure symbol and decimals auto-fill (verify via block explorer if needed).
- Click Add Custom Token, then Import Tokens.
The token will now appear in your wallet balance.
💡 Tip: Even unimported tokens are safely stored in your wallet—you just need to import them to see the balance.
Frequently Asked Questions (FAQ)
Can I use Polygon with MetaMask on mobile?
Yes! While the Polygonscan one-click method doesn’t work on mobile, you can manually add Polygon by entering the network details in the app under Settings > Networks > Add Network.
Is there a fee to transfer funds from Ethereum to Polygon?
Yes, but it’s relatively low. Using the Polygon Bridge, transferring ETH from Ethereum to Polygon typically costs $1–$5 in gas, depending on network congestion.
What is the correct Chain ID for Polygon?
The Chain ID for Polygon Mainnet is 137. Always double-check this value when adding manually to avoid scams.
Why can’t I see my tokens after switching to Polygon?
Make sure you’ve added the correct network and imported any custom tokens. Balances don’t carry over automatically from Ethereum—you must bridge assets first.
Can I switch back to Ethereum after adding Polygon?
Absolutely. Just click the network dropdown in MetaMask and select “Ethereum Mainnet” or any other added network. Your wallets are shared across networks.
Is adding Polygon to MetaMask safe?
Yes—as long as you use official sources for RPC URLs and contract addresses. Never trust links from social media or unknown websites.
