How to add Polygon(MATIC) to MetaMask Network

The launch of CrowdSwap’s token (CROWD) will happen on the Polygon (MATIC) network. For the upcoming MASSIVE airdrop lottery and the token launch, we chose Polygon for the genesis event. Polygon network has some features that make it unique for our airdrop, hence the reason why we chose Polygon for this purpose. Before going any further, let’s take a look at the main characteristics of the Polygon network.

What Is Polygon (MATIC)?

Known also as Matic Network, the Polygon Network is a layer-2 scalability platform that was introduced as a solution to increasing the scalability of the Ethereum Network. The Polygon Network utilises a very versatile framework called Polygon SDK, which is described by the project as the “Gateway to Multi-Chain Ethereum”. The native token of Polygon network is MATIC, which has attracted a lot of attention to it in recent years.

The Polygon Network brings secure, convenient and fast off-chain transactions not only for payments, but also for off-network smart contracts. In fact, Polygon is a platform for building a dedicated blockchain network, combining all the features of an independent blockchain (flexibility, governance, and scalability) with the best features of Ethereum (security, developer experience, and cross-chain collaboration).

The main goal of the Polygon network is to provide a framework for building blockchain networks that can communicate with each other. Polygon has several innovative features such as ZK and Optimistic roll-ups. The ZK Roll-up takes a large number of transfers out of the network and consolidates them into single transactions. In addition, the Optimistic roll-up feature speeds up the transaction time. Both of these features help increase scalability and solve Ethereum’s current problem of network congestion and high transaction fees. Polygon processes up to 65,000 TPS (transactions per second) in a single sidechain, and the confirmation time of each block is under 2 seconds.

It is because of these features that the polygon network has reached a ton of interest. Transaction fees in the MATIC network are extremely low, which are sometimes cheaper than $0.001! Blazing fast transaction speeds make it an optimal place to start our journey. As you know, one of the main goals of CrowdSwap is to offer solutions for lower fees and fast transactions. Therefore, the features of Polygon Network described above make it the go-to blockchain network for our team to launch the CROWD token.

How to Add Polygon to MetaMask?

To participate in both the airdrop and token launch of CROWD token, you need to set up a wallet that supports the Polygon network for exchanging tokens to each other. For this purpose, we suggest using MetaMask Wallet, which is easy to set up. If you already have a MetaMask Wallet, you can use it, but if you don’t, this article helps you set up a MetaMask wallet to get you started. But before we start, make sure you have a pen and a paper at hand to make a backup of your wallet and you secure it somewhere to make sure that nobody but you has access to your recovery key.

1. Install the MetaMask extension on your browser

To install the MetaMask extension go to the MetaMask Download page and select the appropriate version. You can either select to install mobile on iOS or android. This guide will concentrate on the browser setup. Mobile ones should almost be the same.

Scroll down to the section and choose the browser version that you are using.

2. Create your wallet

After successful installation of the MetaMask extension, you can start to create your own wallet.

> Click “Get started”

After following the get started route, you will see this dialog, where you can choose to create your new wallet or import an existing wallet.

> Click “Create a Wallet”

First step is to create a password for your wallet. It has to have at least 8 characters. 

!! Choose a complex password or use a password generator to create a random password. You are responsible for your assets now !!

> Enter the password

> Repeat the password to confirm it

> read the “terms of use” and check it

> Click the “create” button 

> Write down the sequence of words

You will be presented with the recovery phrase. This sequence of words is very important. You need it to import your wallet into the MetaMask extension. So, write it down and confirm this on the dialog

> Confirm that you wrote it down somewhere

> Click “Next”

Congratulations!

You have successfully created a wallet!

> Move on to step 3

3. Add the polygon (MATIC) network to MetaMask

Before you can use the MetaMask wallet on the polygon network, you have to provide the connection details to the MetaMask extension. This is done by adding a new network. This is an easy task and takes you just 1 minute.

> Open the MetaMask extension and click on the icon in the top right .

The main menu of MetaMask opens. 

> Click on the menu entry “Settings”. 

In the setting menu:

> Scroll down to the “Networks” item and click it.

You will see all the networks that have been automatically created when you installed the MetaMask extension.

> Click the “Add network” button

You have reached the dialog, where you have to define the details of the network. 

> Insert the data below in the corresponding fields of the MetaMask dialog.

Network Name: Matic Network

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

Chain ID: 137

Currency Symbol (optional): MATIC

Block Explorer URL (optional): https://explorer.matic.network

> Click Save and you are done!

PRO Tip:

In times of congested networks, sometimes changing the RPC URL helps out:

• https://rpc-mainnet.matic.network
• https://rpc-mainnet.maticvigil.com
• https://rpc-mainnet.matic.quiknode.pro
• https://matic-mainnet.chainstacklabs.com
• https://matic-mainnet-full-rpc.bwarelabs.com
• https://matic-mainnet-archive-rpc.bwarelabs.com

4. Done

Congratulations! You have created your MetaMask wallet and configured the Polygon network. Now you are set for participating in CROWD token launch.
