Now that you have your wallet, you'll need to add the Polygon network to MetaMask. Here's how:
-
Open your MetaMask wallet and click on the network dropdown (it usually displays "Ethereum Mainnet").
-
Select "Add Network".
- Find the Polygon MainNet in the "Popular" list and add it.
- In case you don't see it there, this is how to manually add it by clicking on "Custom Networks" instead.
- Fill in the following details:
- Network Name: Polygon Mainnet
- RPC URL: https://rpc-mainnet.maticvigil.com/
- ChainID: 137
- Symbol: POL
- Block Explorer URL: https://explorer.matic.network/
-
Click "Save."
Congratulations! You've successfully added the Polygon network to your MetaMask wallet.
