MetaMask is a crypto wallet app and browser extension that, by default, is connected to the ETHereum mainnet. To connect to other networks like Polygon, you'll need to add some basic blockchain information to MetaMask. This includes a custom RPC URL, chain ID, and network name. To add Polygon tokens, a token address must be
Setting up your browser wallet to connect to Polygon is simple and can be done in just a few minutes. In this article, we’ll break down how to add Polygon to Metamask step-by-step so anyone can easily follow along and interact with dApps on the Polygon network.
How To Add Polygon To Metamask
1. Adding Polygon support to your wallet involves adding some network details to the extension. First, open MetaMask and click the network dropdown menu.
2. Now, click [Add Network] on the pop-up.
3. You’ll need to add the following details on the [Add a network] page that will open.
- Network Name: Polygon
- New RPC URL (Choose any of the following):
- https://polygon-rpc.com
- https://rpc-mainnet.maticvigil.com
- https://rpc-mainnet.matic.network
- https://rpc-mainnet.matic.quiknode.pro
- Chain ID: 137
- Currency Symbol: MATIC
- Block Explorer URL: https://polygonscan.com/
Click [Save] when you’re finished.
4. You’ll now successfully be connected to the Polygon network.
Adding Polygon tokens to MetaMask
For Polygon tokens other than MATIC to appear on the wallet UI, you will need to add them manually. Note that your wallet can still receive tokens that haven’t been imported.
1. First, head to PolygonScan and find the token contract and details of the token you’d like to add. If the token is not on PolygonScan, make sure to get the contract address from the project’s official website or social media channels. Be careful with fake contracts created by scammers.
2. Return to MetaMask and click [Import tokens].
3. Copy in the token’s contract address and MetaMask should automatically fill in the rest of the details. If not, add them manually. To finish, click [Add Custom Token].
4. Click [Import Tokens].
5. Your wallet will now successfully display the balance of the token added.
Closing Thoughts
While MetaMask was initially built for ETHereum, you can now use it across multiple blockchain networks, including Polygon, Avalanche, Binance Smart Chain, and others. Learning how to add each network manually will allow you to explore the various DeFi platforms and DApps of each blockchain ecosystem, such as PancakeSwap, Uniswap, SushiSwap, and OpenSea.
But now that you have learnt how to add Polygon to MetaMask, you can start by exploring the Polygon ecosystem – swapping on the QuickSwap DEX, playing games in ETHlas, and much more!
