Copy the endpoint with your API key and use it as the RPC URL. Add details to MetaMask:

  • Network Name: Polygon Mainnet

  • New RPC URL: https://polygon-mainnet.rpcfast.com?api_key=YOUR_KEY

  • Chain ID: 137

  • Currency symbol: MATIC

  • Block explorer URL: https://polygonscan.com/

Your final result will look like this:

Adding Polygon tokens to MetaMask

After adding Polygon to MetaMask, you will already see MATIC tokens in your wallet. MetaMask also makes it easy to add new tokens, for example, if you’re minting your own in a dApp. Here’s how you can do it in two steps:

  1. Navigate to the bottom of your wallet and hit Import Tokens.

  2. Specify your address, token symbol, and decimal. In this case, it’s TST on a test contract.

Now that you’ve finished the Polygon MetaMask setup, you can allow users to interact with your dApp directly and unlock the full potential of Web3 with the help of RPC Fast.

Setting up Polygon on MetaMask allows you to bridge the gap between Web2 and Web3, interacting with your dApp from a browser extension. All you need to do is create a wallet, connect it to your RPC Fast API, and add any tokens you plan to work with.

From now on, you can interact with the chain and build amazing things with the help of Polygon’s robust scaling and lightning-fast transaction speed.
