Setup MetaMask

MetaMask

1. Download MetaMask

Click the link https://metamask.io/download.html to install MetaMask for your browser.

Note: Depends on if you have a private key or not, you can either import the private key to create a wallet; or, you can create a wallet directly. It's very important to remember the mnemonic and private key. If you lost it, you can also enter the wallet and export the private key.

2. Add Polygon Mainnet

Add a custom RPC network to connect your wallet account to the Polygon mainnet, configure Polygon mainnet parameters as follow:

Parameters	Value
Network Name	Polygon Mainnet
RPC URL	https://polygon-rpc.com/
ChainID	137
Symbol	MATIC
Block Explorer URL	https://polygonscan.com/

After the parameters are configured, click 'Save' button below and successfully add Polygon mainnet.

If you want to add more wallet accounts, you can create them by importing the private key of your existing other wallets; or, you can directly click Create Account, and remember to save the private key after creation.
