How to add polygon to MetaMask?

In this article, we will show you how to add Polygon (MATIC) to MetaMask, which will allow you to use MetaMask to interact with the Polygon network just like you do with Ethereum.

Once you add the Polygon Network to MetaMask, you can store and send Polygon-based tokens and seamlessly use decentralized applications deployed on the Polygon Network.

All you need before adding Polygon to MetaMask is to install the MetaMask browser extension or mobile wallet. You don’t even need tokens to get started, although having some MATIC tokens will be necessary if you want to conduct any kind of transaction on the Polygon network.

How can I add Polygon to MetaMask?

Before we start the guide, we would like to point out that while using Polygon with the MetaMask wallet is extremely convenient, it is also not the best idea from a security perspective if you only use MetaMask software and do not supplement it with a hardware wallet .

If you want to make your cryptocurrencies significantly more secure, we recommend purchasing a Ledger hardware wallet. You can connect your Ledger wallet to MetaMask so you can enjoy the best of both worlds: the convenience of MetaMask and the security of Ledger.

Now let’s get started with our detailed guide to adding the Polygon Network to your MetaMask wallet.

1. Go to the “Institutions‘ section of your MetaMask wallet
2. Choose the Polygon network
3. (Optional) Add the Polygon network manually
4. Import any custom polygon-based tokens you want to use

1. Go to the “Settings” section of your MetaMask wallet

Open your MetaMask wallet and then click on the profile icon at the top right of the user interface. Then select “Institutions‘ from the drop-down menu that appears.

2. Once you are in the “Institutions“menu, select”Networking.”

Here you can see the list of networks your MetaMask is currently configured to work with. Click “Add network” to add Polygon to your MetaMask wallet.

2. Choose the Polygon network

As you will be able to see, Polygon is already listed as one of the popular networks that users like to use with MetaMask, which makes the process of adding it to your MetaMask even easier. Just click on “Add” next “Polygon main mesh‘ and then click ‘Approve.”

3. (Optional) Add polygon manually

If you don’t see the Polygon network in the list, don’t worry. You can easily add it manually. Click “Add a network manually‘ and then enter the following information:

• Network name: Polygon main mesh
• New RPC URL: https://polygon-rpc.com
• Chain ID: 137
• Currency symbol: MATIC
• Block Explorer URL: https://polygonscan.com

If you have provided this information correctly, MetaMask will inform you that you have switched to the Polygon Mainnet.

When you reopen your MetaMask wallet, you will see that the default currency has changed from ETH to MATIC and that you are currently using the Polygon Mainnet. If you want to switch back to Ethereum or another network, you can easily do so from the menu at the top of the MetaMask interface.

How can I add polygon-based tokens to MetaMask?

You don’t need to manually add MATIC to MetaMask after moving to the Polygon network. However, you will need to manually add any other Polygon-based tokens you want to use.

Find the contract address of the token using a block explorer

In our example, we add information about the USDC token on the Polygon network to our MetaMask wallet. You’ll need the token’s contract address, which can be found in any Polygon block explorer. We will use the PolygonScan block explorer.

We are looking for “USDC” on PolygonScan and go to the first result. Below “Profile Resume“, you can see the contract address. Copy it.

Import the token’s information into MetaMask

Then go back to your MetaMask wallet and select “Import tokens.”

In the “Token contract address‘, paste the contract address you copied from PolygonScan. Then MetaMask should be able to automatically detect the token symbol (“USDC”) and the decimal amount (“6”). If everything is correct, click on “Add custom sign.”

You can use the same process for any other polygon-based token you want to use. Make sure you find the correct token on PolygonScan or another block explorer of your choice and copy the correct address.

What other blockchains does MetaMask support?

You can use MetaMask with most blockchains compatible with the EVM (Ethereum Virtual Machine). Here are some examples of EVM-compatible blockchains that can be used with MetaMask.

• Polygon
• BNB chain
• Arbitration
• Avalanche
• Phantom

The process of adding each of these networks to MetaMask is much the same as adding Polygon, although each network will have its own name, RPC URL, chain ID, currency symbol, and block explorer URL.

The bottom line: adding new networks to MetaMask is easy

As our guide has hopefully shown, the process of adding Polygon to MetaMask is quite simple. You can also use the same process you learned here to add other compatible networks, like adding BNB Chain to MetaMask for example.

Choosing the right cryptocurrency wallet is a crucial step for every cryptocurrency investor and user. If you choose to use a software wallet like MetaMask, we recommend combining it with a high-quality hardware wallet.
