| New RPC URL | https://polygon-rpc.com |
| Chain ID | 137 |
| Currency Symbol | MATIC |
| Block Explorer URL | https://explorer.matic.network |
After entering the information as described, click on the “Save” button to finalize the addition of the network.
Step 5: Switch to the Polygon Network
Once the network has been added, you will automatically be redirected to the new network. If not, click on the network dropdown again and select “Polygon Mainnet.” The interface should now reflect your connection to the Polygon network.
Step 6: Using Polygon with MetaMask
With Polygon connected to your MetaMask wallet, you can now begin exploring dApps built on the Polygon network. Check out popular options such as:
- QuickSwap: A decentralized exchange that allows trading of assets directly from your wallet.
- Aave: A lending platform offering competitive interest rates for borrowing and lending cryptocurrencies.
Troubleshooting Common Issues
In your journey to connect MetaMask to Polygon, you may encounter some issues. Here are common problems and their solutions:
Failed Transactions
If your transactions on Polygon fail, ensure you have enough MATIC in your wallet to cover transaction fees. Should you encounter further difficulties, try adjusting the gas settings in MetaMask.
Unable to Access dApps
If you cannot access certain dApps, verify that you are connected to the correct network (Polygon Mainnet) and that your wallet balance is adequate for transactions.
Incorrect Network Settings
Double-check the RPC URL, Chain ID, and other settings in MetaMask. A small typo can lead to connection issues.
Additional Tips for Optimal Use of Polygon with MetaMask
Now that you’re connected, here are some additional tips to optimize your experience:
Keep Your Wallet Secure
Ensure your private keys and seed phrases remain confidential and secure. Use hardware wallets for added security wherever possible.
Stay Informed
Follow updates from the Polygon team and the broader crypto community. This knowledge can help you adapt to changes in services or protocols.
Regular Backups
Periodically back up your wallet data to prevent loss. MetaMask provides options for exporting private keys, which should be kept securely in encrypted storage.

What is Polygon and why would I want to connect it to MetaMask?
Polygon is a Layer 2 scaling solution for Ethereum that enhances the network’s speeds, reduces transaction costs, and improves overall user experience. By employing sidechains, Polygon allows for faster and cheaper transactions, making it an attractive choice for decentralized applications (dApps) and users looking to navigate the Ethereum blockchain without facing the common issues of congestion and high fees.
Connecting Polygon to your MetaMask wallet enables you to interact with various applications and services built on the Polygon network. This seamless integration allows users to take advantage of lower fees, quicker transactions, and a thriving ecosystem of dApps while maintaining the security and functionality that MetaMask offers.
How do I add Polygon to my MetaMask wallet?
To add Polygon to your MetaMask wallet, start by opening your MetaMask extension and click on the network dropdown menu at the top. Select “Custom RPC” from the list of options, which will allow you to manually enter the network’s details.
You will then need to fill in the appropriate details for the Polygon network: enter the network name (e.g., “Polygon”), the RPC URL (e.g., “https://polygon-rpc.com”), the Chain ID (which is 137), the currency symbol (MATIC), and the Block Explorer URL (optional, e.g., “https://explorer.matic.network”). After filling in this information, click “Save” to complete the addition of the Polygon network to your MetaMask wallet.
Are there any fees associated with using Polygon and MetaMask?
Yes, while Polygon offers significantly lower transaction fees compared to Ethereum, there are still costs involved when performing transactions or interacting with dApps on the network. These fees are usually paid in MATIC, the native cryptocurrency of the Polygon network. It’s important to keep some MATIC in your wallet to cover these expenses for smooth transactions.
Additionally, you should consider any potential fees that might be incurred during the token bridge process if you are moving assets between Ethereum and Polygon. These fees depend on the method and platform you choose for bridging your tokens, which can vary significantly between services.
Can I transfer tokens from Ethereum to Polygon using MetaMask?
Yes, you can transfer tokens from Ethereum to Polygon using MetaMask by utilizing a bridging service. One popular option for bridging tokens is the official Polygon Bridge. To get started, make sure your MetaMask wallet is connected to the Ethereum network and has the token you wish to transfer.
After accessing the Polygon Bridge, follow the prompts to connect your MetaMask wallet. You will select the token you want to transfer and enter the amount. Confirm the transaction in your MetaMask wallet, and once the transfer is complete, you can switch your network to Polygon to access the tokens on that chain.
What dApps can I access on the Polygon network using MetaMask?
Polygon hosts a myriad of dApps across various categories, including DeFi platforms, NFT marketplaces, and gaming applications. Some of the most popular dApps include Aave, QuickSwap, and OpenSea, which provide users with decentralized finance options, trading platforms, and non-fungible tokens, respectively. The growing ecosystem of Polygon means users can explore a diverse range of projects and services.
You can access these dApps by ensuring your MetaMask is set to the Polygon network and visiting their websites directly. Connecting your wallet is usually as simple as clicking a “Connect Wallet” button on the platform, allowing you to interact with the dApp and utilize its services seamlessly.
What should I do if I encounter issues connecting Polygon to MetaMask?
If you encounter issues while trying to connect Polygon to MetaMask, the first step is to double-check the network settings you’ve entered. Ensure that the RPC URL, Chain ID, and other details are correct, as even a small error can prevent a successful connection.
If the settings are correct but you’re still facing challenges, try restarting MetaMask or your browser, clearing your browser’s cache, or checking for MetaMask updates. If problems persist, visiting the official Polygon or MetaMask support resources may provide solutions, as many users face similar issues.
