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, Polygon enables developers to build fast, user-friendly decentralized applications (dApps) with significantly lower transaction fees, all while inheriting Ethereum’s robust security framework.
Meanwhile, MetaMask stands as the leading non-custodial cryptocurrency wallet in the Web3 ecosystem. Trusted by millions worldwide, MetaMask allows users to seamlessly store, send, receive, and trade digital assets across multiple blockchain networks. Its browser extension and mobile app support Ethereum Virtual Machine (EVM)-compatible chains, making it an ideal tool for interacting with the Polygon network.
Because Polygon operates as an EVM-compatible sidechain of Ethereum, adding it to your MetaMask wallet is a straightforward process. This guide walks you through every step—whether you're using the desktop extension or mobile app—to safely and securely integrate Polygon (MATIC) into your wallet.
Why Add Polygon (MATIC) to MetaMask?
Integrating the Polygon network into your MetaMask wallet unlocks access to a thriving ecosystem of DeFi platforms, NFT marketplaces, and gaming dApps. With MATIC as the native currency, you can pay for transactions, stake tokens, and participate in governance across hundreds of decentralized services.
Adding Polygon is essential if you plan to:
- Use dApps on platforms like Aave, QuickSwap, or OpenSea (Polygon)
- Reduce gas fees compared to Ethereum mainnet
- Explore cross-chain opportunities via bridges
- Store and manage MATIC and other Polygon-based tokens

How to Add Polygon Network to MetaMask (Step-by-Step)
Follow these steps to add the Polygon mainnet to your MetaMask wallet using the custom RPC method.
Step 1: Open and Unlock MetaMask
Launch your MetaMask extension or app and enter your password to unlock your wallet. If you haven’t installed MetaMask yet, visit the official website to download the correct version for your browser or device.
Step 2: Access Network Settings
In the top-center of the MetaMask interface, click the current network dropdown (e.g., “Ethereum Mainnet”). From the list, select “Add Network.”
Step 3: Enter Polygon RPC Details
Fill in the following configuration for the Polygon Mainnet:
- Network Name: Polygon Mainnet
- New RPC URL:
https://polygon-rpc.com/ - Chain ID: 137
- Currency Symbol: MATIC
- Block Explorer URL:
https://polygonscan.com/
Ensure each field is entered exactly as shown. Incorrect details may lead to failed transactions or loss of funds.
Step 4: Save and Confirm
Click “Save” to finalize. MetaMask will verify the connection and automatically switch to the Polygon network. You should now see “Polygon Mainnet” displayed at the top of your wallet.
If it doesn’t switch automatically, manually select “Polygon Mainnet” from the network dropdown.
Adding Polygon on MetaMask Mobile App (iOS & Android)
The mobile version of MetaMask simplifies network addition with pre-configured options.
Step 1: Unlock Your Wallet
Open the MetaMask app and authenticate using your password or biometric login (Face ID, fingerprint).
Step 2: Navigate to Networks
Tap the menu icon (☰) in the top-left corner, then go to Settings > Networks.
Step 3: Add Polygon Mainnet
Tap “Add Network,” then switch to the “Popular” tab. Locate and tap “Polygon Mainnet.”
Step 4: Approve and Confirm
Review the network details and tap “Approve,” followed by “Add.” The network will be added instantly.
You’re now ready to interact with any dApp on the Polygon blockchain directly from your mobile device.

How to Transfer MATIC to Your MetaMask Wallet
To use the Polygon network, you’ll need MATIC tokens for gas fees. Here’s how to deposit them:
- Obtain Your Wallet Address
In MetaMask, ensure “Polygon Mainnet” is selected. Copy your wallet address (the 42-character string starting with0x). - Withdraw from Exchange
On a supported exchange (like Binance), go to Wallet > Withdraw and search for MATIC. - Select Polygon Network
Choose “MATIC (Polygon)” or “ERC-20 via Polygon” as the withdrawal network. Paste your MetaMask address. - Confirm Transaction
Enter the amount and confirm using 2FA. Withdrawal typically takes 5–20 minutes. - Check Balance
Return to MetaMask, refresh the balance, and verify the MATIC has arrived.
⚠️ Always double-check the network before sending funds. Sending MATIC via Ethereum (ERC-20) instead of Polygon may result in lost assets.
Adding Wrapped ETH (WETH) on Polygon via MetaMask
Since native ETH isn’t used directly on Polygon, you’ll need Wrapped ETH (WETH) to trade or provide liquidity.
Step 1: Ensure Polygon Network Is Active
Switch MetaMask to Polygon Mainnet.
Step 2: Import WETH Token
Click “Import Tokens” at the bottom of the wallet interface.
Enter the WETH contract address for Polygon:
0x7ceb23fd6bc0add59e62ac25578270cff1b9f619MetaMask will auto-fill the token symbol (WETH) and decimals (18).
Step 3: Import Token
Click “Add Custom Token,” then “Import Tokens.” WETH will now appear in your asset list whenever you hold a balance.
You can acquire WETH by bridging ETH from Ethereum to Polygon using the official Polygon Bridge, or by swapping MATIC for WETH on a decentralized exchange like QuickSwap.
Frequently Asked Questions (FAQ)
Can I use the same MetaMask address for Polygon?
Yes. MetaMask uses a single address across all EVM-compatible networks, including Ethereum and Polygon. Your MATIC and other Polygon-based tokens will appear when you switch to the Polygon network.
Is adding Polygon to MetaMask safe?
Yes, as long as you use official RPC endpoints like https://polygon-rpc.com/. Avoid third-party or unverified RPC URLs that may compromise security.
Why can’t I see my MATIC after transfer?
Ensure your MetaMask is set to Polygon Mainnet, not Ethereum. Also, refresh your balance manually. Transactions may take several minutes to confirm.
Do I need ETH on Ethereum to use Polygon?
Only if you plan to bridge assets from Ethereum to Polygon. Otherwise, you can buy MATIC directly on exchanges and withdraw it to your Polygon-enabled MetaMask wallet.
Can I add other tokens on Polygon?
Yes. Use the “Import Tokens” feature in MetaMask and input the correct contract address from a trusted source like Polygonscan.
What is the difference between MATIC and WETH on Polygon?
MATIC is the native gas token of the Polygon network. WETH is a wrapped version of ETH used for trading and liquidity provision—it maintains a 1:1 value with ETH but functions as an ERC-20 token on Polygon.
