Next we will give you a brief explanation of what MetaMask is, as well as help you to configure your wallet and connect it to the Polygon network in a fast and easy way. Remember that having a MetaMask wallet is needed to see all the information of the NCB in our app.
What is MetaMask and what is it used for?
MetaMask is an extension or plugin for browsers and a mobile app, which works as a gateway to interact with the Ethereum blockchain and the decentralized applications that are within it; and also offers a digital wallet for users to protect their crypto assets. It should be noted that this is a fully decentralized wallet, and it is considered the most secure by its community of more than a million users.
This development has managed to create a bridge between the web browsers that people use (Chrome, Firefox, Brave, etc.), mobile devices and decentralized applications of Ethereum, which has facilitated access to them by a large number of users. people around the world.
How to create a MetaMask wallet?
MetaMask has a fairly quick and easy installation process, since it allows you to create your wallet without the need to carry out laborious configuration and identification processes.
Next, we will guide you step by step to install the MetaMask extension and carry out the quick configuration process so that you can have your digital wallet ready to use in just a few minutes.
1. Download the MetaMask extension
It’s very simple, you just have to access the extension marketplace of the browser of your choice. Below we provide you with the download links for the MetaMask extension for some of the most used browsers:
Remember that it is vitally important to download these extensions from official sites, as phishing cases can occur due to the installation of extensions from malicious websites.
2. Start the wallet setup process
Once the extension has been successfully installed, access it and click “Get Started” once the welcome screen has been displayed.
3. Create your wallet
The next screen will display two options, import wallet and create a wallet. If you want to create a new wallet, select the second option. On the other hand, if you already have a wallet and want to import, select the first option, for which you must have your seed phrase and your wallet password.
4. Accept the terms and conditions
Unlike other types of platforms, MetaMask will allow you to create your wallet whether or not you accept its terms and conditions. It should be noted that this is done completely anonymously.
5. Create a password for the wallet
The time has come to create a password which will allow you to unlock your wallet in order to access and use it. We recommend using random alphanumeric passwords, as this will make it very hard for anyone to hack your wallet and access your funds. In addition, it is very important to keep it in a safe place, since in case you lose it, you will not be able to access it again and therefore your funds.
6. Obtain and protect your seed phrase
MetaMask will provide you with a randomly generated 12-word phrase, known as a seed phrase. It is also of vital importance that you back it up securely, either virtually or even write it down on paper, since it has the same importance as your password when accessing your wallet.
Once you have copied it correctly and click “Confirm”, your wallet will be configured and ready to use.
How to connect my wallet to the Polygon network?
Once you have successfully created your MetaMask wallet, it will be connected to the Ethereum network. However, you will be able to access different networks in order to have access to a greater variety of decentralized applications (in order to purchase an NCB, your wallet must be connected to the Polygon network).
1. Access the blockchain networks menu
In order to connect the Polygon network to your wallet, you will need to add network information to your extension. You will first need to open MetaMask and click on the network dropdown menu, located at the top right. Then click on “Add Network”.
2. Configure the Polygon network
Once you have clicked here, different spaces will be displayed in which you must enter the following information:
- Network Name: Polygon
- New RPC URL: https://polygon-rpc.com
- Chain ID: 137
- Currency Symbol: MATIC
- Block Explorer URL: https://polygonscan.com/
Then click ”Save”. At this point, you will have successfully connected to the Polygon network.
Once you have a MetaMask digital wallet linked to the Polygon network, you will be able to store your NCB, which will be securely stored in it. Remember that it is very important that you save your password and your seed phrase (preferably in some offline medium), as well as not sharing it with anyone to avoid significant financial losses.
