As a second step on Settings, go to Networks, New Network and write the information for Polygon Network such as the one described below:

2nd Step

Network Name: Polygon

New RPC URL: https://rpc-mainnet.matic.network/

Chain ID: 137

Currency Symbol: MATIC

Block Explorer URL: https://explorer.matic.network/

On the main page, you will see that you’re connected to Polygon Network already, now you can connect your wallet to any service that requires Polygon.

How to Bridge Ethereum to Polygon

Making a bridge through Ethereum Network and Matic is a simple process as well, however, to make transactions on Polygon Network it’s required that you have Matic Tokens in your wallet, just like the BSC network requires BNB tokens.

To buy Matic tokens you can search for any suitable exchange on Coingecko that offers Matic tokens, then you need to withdraw those tokens to your Metamask Wallet Address.

Now you’ve got Matic tokens in your wallet to make transactions on Polygon network, and you should have Ethereum tokens to Bridge them to Matic Network through the steps below.

Join Polygon Network Website through this Link, you will be redirected directly to Polygon Bridge Website.

Connect your Metamask Wallet to Polygon Network Interface.

You can now select the Token that you want to bridge to Matic Network, in our case, it’s Ethereum, so you select the amount of Ethereum that you want to Bridge and Transfer.

Keep in mind that moving funds through a bridge takes a bit more time.

You will need to Approve the Transaction and Completing it by paying Ethereum Fees at first

That’s it!, now you’ve got tokens on Matic Network!
