The Polygon network (formerly known as the MATIC network) is one of the leading layer-2 decentralized scaling solutions for the Ethereum blockchain.
Polygon (MATIC) enables developers to build scalable user-friendly dApps with low transaction fees without sacrificing speed or security since the network inherits security from the Ethereum chain itself.
The Metamask wallet in contrast is the most popular open-sourced non-custodial wallet in the crypto space. It is used by millions of crypto investors across multiple operating systems to purchase, store, and trade cryptocurrencies and other digital assets with ease.
Since the Polygon Network is a sidechain for the Ethereum mainnet, it is compatible with the Ethereum Virtual Machine (EVM) i.e smart contracts are deployed directly on the Polygon chain. Being an EVM-compatible chain also means that it can be added to Metamask via RPC.
If you’re looking to add the Polygon network to your Metamask wallet, then you’re on the right article. In this guide, we will show you how to add the Polygon mainnet to Metamask easily in a few steps.

How Transfer Polygon To Your Metamask Wallet Easily
To fully utilize your Metamask wallet on the Polygon network, you need to transfer some MATIC tokens (the native token of the Polygon network) from an external wallet or crypto exchange account (that holds some value in MATIC) to your Metamask wallet.
If you don’t currently hold any MATIC tokens, we recommend using Binance to purchase some MATIC since the cryptocurrency is supported by the exchange, and most importantly, it can be transferred out to external wallets like Metamask.
You can sign up for a free Binance account using this link.
Once you have created an account on Binance, purchase some MATIC using your credit/debit card, direct bank deposit, third-party payment providers, or via P2P before moving on with the guide below. Binance provides an excellent tutorial on how to do that in this article.
To send MATIC from Binance to your Metamask Wallet, you need to copy your default Metamask wallet address since Metamask only provides one wallet address which is used across multiple (configured) blockchains/networks on your wallet and this includes the Polygon network.
Now that you have your Metamask wallet address which is also your MATIC wallet address, head over to the Binance mobile app or web dashboard, then tap on [Wallets], and select [Funding] to navigate to your funding wallet.
Next, tap on [Withdraw], search for “MATIC” and select “MATIC Polygon” from the results. Now, select [Send via Crypto Network] from the bottom dialog.
On the next page, enter your Metamask MATIC wallet address in the wallet address section then select “Polygon” as the network to be used for the transaction.
Enter the amount of Polygon (MATIC) tokens to be transferred to your Metamask wallet from Binance and tap on [Withdrawal].
Now, tap on [Submit] and complete the 2-step verification by providing the code sent to your phone number, email, and/or authenticator app (Google or Binance authenticator).
Finally, head back to your Metamask wallet and refresh your MATIC balance to view the updated balance.
The transaction can take anywhere from 5 – 20 mins to complete so you have to be a bit patient just in case the tokens aren’t available in your wallet yet.
How To Add ETH To Polygon Network On Metamask
To add ETH to the Polygon on Metamask, you first need to add the Polygon Mainnet to your Metamask wallet as explained in the guide above.
Since there is no Native Ethereum deployed on the Polygon chain, you will need to add the Wrapped version of Ethereum (WETH) to the Polygon network on your Metamask wallet if you want to trade with ETH on the Polygon network.
While Wrapped Ether (WETH) is not the native Ether (ETH) token we all know, it is the ERC-20 compatible version of Ether and it has the same value as the ETH token since WETH is created by sending ETH to a smart contract where the ETH is placed on hold until it ready to be redeemed.
Now that you have a basic understanding of what WETH is, let’s learn how to add it to your Metamask wallet on the Polygon network.
First, you will need to get the Contract Address for WETH on Polygon. The correct contract address for WETH on the Polygon network is “0x7ceb23fd6bc0add59e62ac25578270cff1b9f619” and you can find the contract on the Polygonscan explorer.
Now that you have the contract address of WETH on Polygon, you can go ahead and add WETH to your Metamask wallet on the Polygon network using this contract address.
To do this, launch the Metamask extension and ensure that the Polygon Mainnet is added and selected as the default network on your wallet (refer to the guide above if you haven’t done this).
Now, on the Metamask main window, click on [Import tokens].
On the new window, paste in the contract address for Polygon WETH (0x7ceb23fd6bc0add59e62ac25578270cff1b9f619) in the “Token Contract Address” section and wait for some seconds for Metamask to automatically input the Token Symbol and Decimal.
Click on [Add Custom Token].
Finally, click on [Import Tokens] to add Polygon ETH to your Metamask wallet.
After this, you should see your Polygon WETH balance Metmask and you can transfer WETH to your Metamask wallet address using the Polygon network.
Wrapping Up
Well, that’s it. You have successfully added the Polygon network to your Metamask wallet if you followed this guide to the end.
Since the Polygon network is a side chain of Ethereum and an EVM-compatible network, it can be added to Metamask just like other blockchains which are compatible with the Ethereum Virtual Machine (EVM).
To add Polygon to your Metamask wallet, you first need to get the correct custom RPC endpoint for the Polygon Mainnet.
Once you have the RPC details (which were included earlier in the article), you can then head over to the Metamask extension and add the network to your wallet using these RPC details including the Network name, RPC URL, Chain ID, Symbol and Block Explorer URL.
On the Metamask mobile app, things are less technical when adding some of the popular networks to your wallet since these networks come pre-configured on the app.
To add MATIC to your wallet on the Metamask mobile app, you just need to select it from the list of preconfigured networks and tap on [Approve].
