The Polygon network—formerly known as the MATIC network—is one of the most widely adopted Layer-2 scaling solutions for the Ethereum blockchain. Designed to enhance scalability and reduce transaction costs, Polygon enables developers and users to interact with decentralized applications (dApps) seamlessly while maintaining Ethereum’s robust security framework.
MetaMask, on the other hand, is the leading non-custodial cryptocurrency wallet used by millions worldwide. It supports multiple blockchains and offers a user-friendly interface across both browser extensions and mobile apps. Since Polygon is Ethereum Virtual Machine (EVM)-compatible, integrating it into MetaMask is straightforward and allows users to manage MATIC tokens and interact with Polygon-based dApps effortlessly.
If you're looking to expand your crypto wallet’s capabilities by adding the Polygon network, this comprehensive guide will walk you through every step—whether you're using the MetaMask browser extension or mobile app.
Why Add Polygon (MATIC) to MetaMask?
Before diving into the setup process, it’s important to understand why adding Polygon to your MetaMask wallet matters:
- Lower Fees: Polygon drastically reduces gas fees compared to Ethereum mainnet.
- Faster Transactions: Enjoy near-instant transaction finality.
- Access to dApps: Interact with DeFi platforms, NFT marketplaces, and gaming ecosystems built on Polygon.
- Cross-Chain Compatibility: Easily bridge assets between Ethereum and Polygon.

How to Add Polygon Network to MetaMask (Desktop)
Adding the Polygon network to your MetaMask browser extension requires entering custom RPC settings. Follow these steps carefully:
Step 1: Open and Unlock MetaMask
Launch your MetaMask extension in your browser and enter your password to unlock your wallet. If you haven’t installed MetaMask yet, visit the official site to download it—but avoid third-party links.
Step 2: Access Network Settings
In the top-center of the MetaMask interface, click the current network label (e.g., "Ethereum Mainnet"). This opens a dropdown menu showing available networks.
Step 3: Add a New Network
Scroll down and select "Add Network" at the bottom of the list.
Step 4: Enter Polygon Mainnet RPC Details
Fill in the following information exactly as shown:
- Network Name: Polygon Mainnet
- New RPC URL:
https://polygon-rpc.com - Chain ID:
137 - Currency Symbol:
MATIC - Block Explorer URL:
https://polygonscan.com
Double-check each field for accuracy. A wrong Chain ID or RPC URL can lead to lost funds or failed transactions.
Click "Save". The network will be added automatically, and MetaMask will switch to the Polygon Mainnet.
✅ Tip: After saving, ensure “Polygon Mainnet” appears as the selected network in the dropdown.
How to Add Polygon to MetaMask Mobile App (iOS & Android)
The mobile version of MetaMask simplifies the process by preloading popular networks like Polygon.
Step 1: Launch and Unlock the App
Open the MetaMask app on your device and unlock it using your password or biometric authentication (Face ID, fingerprint, etc.).
Step 2: Go to Settings
Tap the menu icon (☰) in the top-left corner, then select Settings.
Step 3: Navigate to Networks
Under Settings, tap Networks, then choose Add Network.
Step 4: Select Polygon Mainnet
Switch to the "Popular" tab. You’ll see a list of commonly used chains. Tap "Polygon Mainnet".
Step 5: Approve Network Addition
Review the network details and tap "Approve", then confirm by tapping "Add Network".
The Polygon network will now appear in your network list and can be selected instantly.

How to Transfer MATIC Tokens to Your MetaMask Wallet
Once Polygon is added, you’ll need MATIC tokens to pay for gas fees and interact with dApps.
Option 1: Buy MATIC on a Centralized Exchange
Platforms like Binance, Coinbase, or Kraken allow you to purchase MATIC using fiat currency (USD, EUR, etc.) via bank transfer, credit card, or P2P trading.
After purchasing:
- Copy your MetaMask wallet address (same across all EVM chains).
- On the exchange, go to Withdraw > Crypto.
- Search for MATIC and select the Polygon (MATIC) network.
- Paste your MetaMask address.
- Enter the amount and confirm withdrawal.
⚠️ Always double-check that you’re withdrawing via the Polygon network, not BEP-20 or ERC-20, to avoid fund loss.
Transactions typically take 5–20 minutes. Once complete, refresh your MetaMask balance to see the updated MATIC amount.
How to Add Wrapped ETH (WETH) on Polygon via MetaMask
Since native ETH isn’t directly available on Polygon, you’ll use Wrapped ETH (WETH)—an ERC-20 token pegged 1:1 with ETH.
Step 1: Switch to Polygon Network
Ensure your MetaMask is set to Polygon Mainnet.
Step 2: Import WETH Token
- Click "Import Tokens" at the bottom of the MetaMask interface.
Paste the WETH contract address for Polygon:
0x7ceb23fd6bc0add59e62ac25578270cff1b9f619- Wait for MetaMask to auto-fill the token symbol (
WETH) and decimals (18). - Click "Add Custom Token", then "Import Tokens".
You’ll now see your WETH balance if you already have tokens on Polygon. To acquire WETH, use a bridge or decentralized exchange like QuickSwap.
Frequently Asked Questions (FAQ)
Q: Is adding Polygon to MetaMask safe?
A: Yes, as long as you use official RPC endpoints like https://polygon-rpc.com. Never input private keys or seed phrases during this process.
Q: Can I lose my funds when switching networks?
A: No—your assets remain secure. However, sending tokens via the wrong network (e.g., withdrawing MATIC on BSC instead of Polygon) may result in permanent loss.
Q: Do I need a new wallet address for Polygon?
A: No. Your MetaMask address works across all EVM-compatible chains, including Polygon.
Q: Why can’t I see my MATIC after transfer?
A: Ensure your wallet is set to the Polygon Mainnet. Also, manually add the MATIC token if it doesn’t appear automatically using its contract address.
Q: Can I stake MATIC directly in MetaMask?
A: Not natively. You’ll need to use staking platforms like the official Polygon Validators portal or trusted DeFi protocols.
Q: What is Chain ID 137?
A: Chain ID 137 uniquely identifies the Polygon Mainnet within EVM ecosystems, ensuring transactions are routed correctly.
Final Thoughts
Integrating the Polygon network into your MetaMask wallet unlocks access to a high-performance blockchain ecosystem with low fees and fast transactions. Whether you're exploring DeFi, collecting NFTs, or participating in play-to-earn games, having MATIC and WETH readily available enhances your Web3 experience.
With just a few clicks—either on desktop or mobile—you can enjoy full compatibility between MetaMask and the Polygon network. Always verify network details before confirming any transaction, and keep your recovery phrase secure.
