The Polygon Network (formerly MATIC) is a leading Ethereum Layer-2 scaling solution, enabling developers to build scalable, low-cost decentralized applications (dApps) without compromising security. Metamask, the most widely used non-custodial crypto wallet, supports Polygon via EVM-compatible RPC integration.
This guide provides step-by-step instructions to add the Polygon Mainnet to Metamask on desktop and mobile, transfer MATIC tokens, and manage wrapped ETH (WETH) on the network.
Quick Steps to Add Polygon to Metamask
- Open Metamask and unlock your wallet.
- Click the network dropdown > [Add Network].
Enter Polygon’s RPC details:
- Network Name: Polygon Mainnet
- New RPC URL:
https://polygon-rpc.com/ - Chain ID: 137
- Currency Symbol: MATIC
- Block Explorer URL:
https://polygonscan.com/
- Click [Save].

Detailed Guide
Step 1: Install and Unlock Metamask
- Download Metamask from the official site if not installed.
- Enter your password to unlock the wallet.
Step 2: Add Polygon Network via RPC
- Click the network dropdown (default: "Ethereum Mainnet").
- Select [Add Network] and input the Polygon RPC details above.
- Confirm by clicking [Save].
Mobile App Instructions (Android/iOS)

Transferring MATIC to Metamask
- Purchase MATIC on exchanges like Binance.
- Withdraw to your Metamask Polygon address (same as Ethereum address).
- Select Polygon network during withdrawal to avoid lost funds.
Note: Transactions take 5–20 minutes.
Adding Wrapped ETH (WETH) to Polygon
Polygon uses WETH (ERC-20 version of ETH). To add it:
- Ensure Polygon Mainnet is active in Metamask.
- Click [Import Tokens] > Paste WETH contract address:
0x7ceb23fd6bc0add59e62ac25578270cff1b9f619. - Confirm details and click [Import].

FAQs
1. Is Polygon compatible with Metamask?
Yes! Polygon is an EVM-compatible chain, allowing seamless integration with Metamask.
2. Why do I need MATIC tokens?
MATIC pays for gas fees on Polygon transactions.
3. Can I send ETH directly to Polygon?
No. Use WETH (wrapped ETH) via bridges or exchanges.
4. How do I check my MATIC balance?
Switch to Polygon Mainnet in Metamask or visit Polygonscan.
5. What if my MATIC withdrawal is delayed?
Confirm the transaction used the Polygon network. Check the explorer for status.
Key Takeaways
- Polygon reduces Ethereum’s fees while maintaining security.
