5. Save and Use: Click “Save” to add the network.

Adding Polygon to the MetaMask mobile app involves a similar process to the desktop version:

1. Open MetaMask App: Launch the MetaMask app on your mobile device.

2. Open menu: Tap on the network dropdown menu at the top of your screen and select “add network”.

3. Select Network: Search for Polygon Mainnet on the list and click “Add”. Check the network details on the screen and click “Approve”.

Alternative: Instead of adding Polygon from the list you can also click on “custom networks”. Proceed as follows:

4. Enter Network Details: In the new screen, enter the Polygon details as follows:

  • Network Name: Polygon Mainnet
  • RPC URL:
  • Chain ID: 137
  • Currency Symbol: MATIC
  • Block Explorer URL (Optional):

5. Add and Switch: Add the network.

For developers or users interested in testing, adding Polygon’s Mumbai-Testnet to MetaMask is beneficial:

1. Open MetaMask and Add Network: Follow the initial steps as described in the manual addition of Polygon.

2. Details for the Mumbai Testnet:

  • Network name: Matic Mumbai
  • RPC URL:
  • Chain ID: 80001
  • Currency symbol: MATIC
  • Block explorer URL:

3. Save and Switch: Save the settings to add the Polygon Testnet to your MetaMask.

In order for the tokens to be visible in the MetaMask, they must first be added. Polygon tokens are the equivalent of native ERC-20 tokens on Ethereum and represent a variety of assets and utilities within the Polygon ecosystem. Here’s how you can import Polygon tokens into your MetaMask wallet:

1. Access Your Wallet: Open MetaMask and ensure you’re on the Polygon network.

2. Find Token Contract Address: Locate the contract address of the Polygon token you want to add. This can usually be found on the project’s website or on Polygonscan.

3. Add Token in MetaMask: Click on “Import tokens” at the bottom of the main MetaMask screen.

Why use the Polygon Network?

The Polygon network as a layer 2 and sidechain solution offers some advantages over Ethereum:

  1. Lower Transaction Fees: Polygon’s architecture significantly reduces transaction costs compared to Ethereum’s mainnet, making it an economical choice for users looking to perform frequent transactions or interact with decentralized applications (dApps).
  2. Faster Transactions: Thanks to its unique structure, transactions on Polygon are processed much quicker than on the Ethereum mainnet, providing a smoother and more efficient user experience.
  3. Ecosystem Access: Adding Polygon to your MetaMask wallet grants you access to a vast and growing ecosystem of dApps, DeFi platforms, and innovative tokens, many of which are exclusive to the Polygon network.
  4. Enhanced Scalability: Polygon addresses some of the fundamental scalability issues faced by the Ethereum network. By facilitating a multi-chain ecosystem, it allows for a significant increase in the number of transactions per second (TPS), making the network more scalable and accommodating for a growing number of users and applications.
  5. Eco-friendly Options: Polygon is committed to becoming carbon neutral and eventually carbon negative. By optimizing transaction efficiency and pledging to invest in environmental initiatives, Polygon presents an eco-friendlier alternative for users conscious about the environmental impact of their blockchain activities.

Jump Start for MetaMask CHANGE

Ensure your MetaMask wallet is set up to add the Polygon network. If you haven’t installed MetaMask yet, follow these steps to do so.

Before adding the Polygon network to your wallet, the first step is to install MetaMask. MetaMask is a popular Ethereum wallet that can be used as a browser extension or a mobile app, providing an easy and secure way to interact with the Ethereum blockchain and its Layer 2 solutions, like Polygon. Here’s how you can install MetaMask:

1. Download MetaMask: Visit the official MetaMask website ( and download the MetaMask extension for your preferred browser (Chrome, Firefox, Edge, Brave or Opera). Install and follow the prompts to add the MetaMask extension to your browser.


2. Create a Wallet: After installation, open the MetaMask extension and select “Create a Wallet”. Follow the instructions to set up your wallet.


3. Create password: Create a secure password. Password managers can help you to create unique and secure passwords.


4. Secure Your Wallet: Write down your recovery phrase and store it in a secure location. This phrase is essential for recovering your wallet if you forget your password or change devices.


5. Confirm recovery phrase: Finish the setup process by filling in the missing words.



Info: If your device gets damaged or lost, you won’t be able to access your funds without the recovery phrase. Remember, to store your secret recovery phrase safely and never disclose it to anyone.

To start using the Polygon network, you need to have some ETH in your MetaMask wallet to pay for transaction fees (gas). To move your ETH from Ethereum (layer 1) to Polygon (layer 2), here are the steps to follow:

1. Connect MetaMask: Open the Polygon Bridge Website and connect your MetaMask Wallet.

2. Select network: Select the network you want to transfer the funds from to Polygon.

3. Select Assets: Select the token and enter the amount you want to transfer to Polygon. Common choices include ETH, but other ERC-20 tokens compatible with the Polygon network can also be selected.

4. Transfer funds: Check the details and click “Bridge”. This step will prompt a transaction in MetaMask, requiring your confirmation. Be mindful of Ethereum gas fees at this stage, as they apply when transacting on the mainnet.

Info: In order to transfer funds to Polygon, you must have the native currency (ETH in this case) available in your MetaMask wallet. If you don’t currently have any ETH in your wallet, you’ll first need to transfer some to your MetaMask wallet from an Exchange or another wallet.

5. Receive funds: Wait for the network to process your transaction. Once confirmed, You should see your transferred funds available in your wallet on the Polygon network.
