This guide explains how to add Polygon Network to MetaMask, enabling access to decentralized DApps and DeFi platforms at significantly lower costs than Ethereum.
Why Use Polygon Network with MetaMask?
MetaMask is a popular Ethereum wallet, but high gas fees on Ethereum have driven users toward Layer-2 solutions like Polygon (formerly MATIC). By switching to Polygon, you retain Ethereum’s security while enjoying faster transactions and lower fees.
Step-by-Step Guide to Add Polygon Network to MetaMask
1. Install MetaMask
- Download the MetaMask extension or mobile app.
- Follow the setup instructions if you’re new to MetaMask.
2. Access Network Settings
- Open MetaMask and click the network dropdown (default: "Ethereum Mainnet").
- Select "Add Network".
3. Enter Polygon Network Details
Fill in the following fields:
| Parameter | Value |
|-------------------------|--------------------------------|
| Network Name | Polygon Mainnet |
| New RPC URL | https://polygon-rpc.com |
| Chain ID | 137 |
| Currency Symbol | MATIC |
| Block Explorer URL | https://polygonscan.com |
4. Save and Confirm
- Click "Save" to connect MetaMask to Polygon.

2. Initiate Token Transfer
- Select "Polygon Bridge" under "Apps".
- Choose MATIC and enter the amount to transfer.
3. Approve and Confirm
- Approve the transaction in MetaMask.
- Wait ~7–8 minutes for the bridge to complete.
Key Features of Polygon Network
- Low Fees: Transactions cost pennies compared to Ethereum.
- High Speed: Faster block times enhance DApp performance.
- EVM-Compatible: Works seamlessly with Ethereum tools like MetaMask.
