If Polygon isn’t preloaded in your MetaMask, you can use PolygonScan, the official block explorer, to add it instantly.

Step 1: Visit PolygonScan

Go to polygonscan.com and ensure your MetaMask is connected.

Step 2: Add Network via Button Prompt

Scroll to the bottom of the homepage. You’ll see a button labeled “Add Polygon Network” or similar. Click it.

MetaMask will open a pop-up displaying the full network configuration. Review the details carefully:

Step 3: Approve and Confirm

Click “Approve”, then “Switch Network” to begin using Polygon immediately.

This method eliminates manual errors and ensures you’re using verified network parameters.

Method 3: Manually Add Polygon to MetaMask Mobile App

For mobile users, adding Polygon manually gives full control over the setup process.

Double-check each field before confirming.

Step 4: Save and Switch

Tap “Save” and return to the main screen. Use the network dropdown to switch from Ethereum to Polygon Mainnet.

You’re now ready to use dApps and receive MATIC tokens on Polygon.

How to Add MATIC Tokens to MetaMask

After adding the network, you may want to view your MATIC balance or add other ERC-20 compatible tokens on Polygon.

Step 1: Switch to Polygon Network

Ensure you're on Polygon Mainnet inside MetaMask.

Step 2: Import Tokens

Scroll down and tap “Import Tokens”.

Step 3: Enter Token Contract Address

For MATIC:

For other tokens, find their contract address on Polygonscan.

MetaMask will auto-fill the symbol (e.g., MATIC) and decimals. Tap “Add Custom Token” to complete.

Frequently Asked Questions (FAQ)

How do I add MATIC to my MetaMask wallet?

First, ensure you’re on the Polygon Mainnet network. Then, copy your MetaMask address and have someone send MATIC tokens directly to it, or swap/buy MATIC via a decentralized exchange like QuickSwap.

Is Polygon the same as Matic?

Yes. The network was rebranded from Matic Network to Polygon, but the native token is still called MATIC. Think of Polygon as the ecosystem and MATIC as its currency.

Can I use ERC-20 tokens on Polygon?

Yes! Polygon supports ERC-20 standards. Many tokens originally on Ethereum have been bridged to Polygon for cheaper transfers and trades.

What is Chain ID 137?

Chain ID 137 identifies the Polygon Mainnet within blockchain systems. It prevents transaction replay across networks and must be entered correctly when manually adding the network.

How do I receive funds on Polygon?

Switch MetaMask to Polygon Mainnet, tap your wallet address to copy it, and share this address with the sender. Only send tokens that are compatible with the Polygon network.

Is it safe to add custom networks like Polygon?

Yes—if you use trusted sources for RPC URLs and Chain IDs. Never add networks from unverified websites or pop-ups. Stick to official sites like Polygonscan or ChainList.

Alternative Method: Use ChainList to Add Polygon

ChainList.org is a trusted aggregator of blockchain networks that allows secure one-click integration with MetaMask.

Step 1: Connect Your Wallet

Visit ChainList and click “Connect Wallet”. Approve connection in MetaMask.

Step 2: Search for Polygon

Type “Polygon” in the search bar. Select Polygon Mainnet (Chain ID: 137).

Step 3: Add to MetaMask

Click “Add to MetaMask”, review the prompt, and approve.

This method ensures accuracy and saves time—ideal for beginners.
