How to link MetaMask to Polygon (MATIC)

The Polygon layer-2 scaling platform (Matic) which enables fast and easy transactions can now easily connect to the MetaMask Ethereum wallet. As a result, users can take full control of their Matic cryptocurrency and they can connect, swap, buy, store and send Ethereum tokens while using the MetaMask wallet. Distribution or exchange for multiple blockchain applications or tokens is also a valid feature. Correspondingly, this article will introduce the DeFi wallet, its benefits and how easy it is to actually connect MetaMask to the Polygon (Matic)network.

What is MetaMask?

In short, MetaMask is a DeFi wallet which is available across multiple channels such as a browser extension and as a mobile application. MetaMask is the cryptocurrency wallet which communicates with the Ethereum blockchain.

The wallet provides users with a key vault, a secure unique login, token wallet, and a token exchange. Therefore, all features are combined in order to make digital asset management quick and efficient.

With MetaMask users can explore different blockchain applications securely as the platform is simple and secure. Web3 can be a difficult to understand place, however MetaMask simplifies the existing process of token-swapping. For example, the wallet generates passwords and keys on your device, so only you have access to your accounts and data. Consequently, users have full control of what data is shared and what information remains private. Once a password or key is generated, the token process becomes very easy. Of course there is a fee for all of the aforementioned features, however MetaMask remains one of the decentralized wallets with lowest fees. Currently, the application charges a fee of less than 1% or to be precise 0.875% for each processed transaction.

Benefits of MetaMask

MetaMask is arguably one of the best wallets for storing your digital crypto assets and as discussed already users can find the best transaction price every time. The wallet singles out prices from different aggregators and markets in order to remain consistent with its 0.875% service fee. In addition, proceeds from the fee itself are reinvested to MetaMask in order to supply users with better quality and improvements.

Gas costs are another benefit why the wallet is largely favored by traders. Each market order or swap requires gas fees to sustain a transaction. As such, the process of swapping tokens identifies best prices and determines the liquidity source which is most gas efficient for each trade. Swapping requires users to approve each token only once in order to gain access to all the available liquidity on DeFi. As a result, time and gas costs are reduced.

The final, but not least of importance benefit is related to slippage protection. Large swaps are usually associated with swift price changes whenever there is not enough liquidity available on a specific decentralized exchange. Therefore, swapping tokens with MetaMask is an automated process which allows user orders to be spread across all DEXs in order to reduce the impact of slippage.

According to MetaMask’s website, their wallet is designed to be privacy-first and to offer the best price slippage protection.

How to connect MetaMask with Polygon?

So after we have covered what MetaMask is and all its benefits, focus shifts on how to link the MetaMask wallet with the Polygon (Matic) network in four easy steps. Without a doubt connecting MetaMask has never been easier.

Step 1.

Initially, users must be registered with MetaMask and have the browser extension enabled. This can be achieved by either installing the MetaMask wallet from their website.

Or as an alternative, users can visit the browser extension marketplace and download the MetaMask extension which will achieve the same result.

Step 2.

The next step is to create a MetaMask wallet or to import an existing one by using the browser extension feature.

Step 3.

After that, to set up MetaMask with the Ethereum token, users have to add a custom RPC network. To accomplish this, users have to open up the browser MetaMask extension and to select the Network button titled Ethereum Mainnet which will open a dropdown menu.

Ethereum Network Selection

The dropdown menu where Custom RPC must be selected should resemble the image below:

Step 4.

After that, users have to navigate and click on the Custom RPC option will prompt them to input data. The data includes: network name, new RPC URL, chain ID, currency symbol and block explorer.

MetaMask Polygon RPC

For convenience, please review Matic’s correct input data below:

Network name: Polygon

New RPC URL: https://rpc-mainnet.maticvigil.com/

Chain ID: 137

Currency symbol: MATIC

Block Explorer URL: https://polygonscan.com

Once users have completed the correct data input and clicked on Save, then they will be able to switch to Matic’s Mainnet from the application’s dropdown list in the future. As a result, MetaMask and Polygon will be successfully linked. Here is an image of the correctly completed custom RPC:

Lastly, users should bear in mind that all transaction fees on the Polygon Network are paid with the MATIC token.
