An Overview of Metamask and Its Functions

This is a guide on how to use MetaMask and how it works. We’ll explain what Metamask is, how it works, and why you might want to use it in your app development or cryptocurrency trading, such as trading XLM to USDT.

What is Metamask?

MetaMask is an Ethereum wallet, which means it’s a software program that allows you to send and receive Ether (the cryptocurrency of the Ethereum network). The difference between MetaMask and other wallets is that it acts as an intermediary between the user interface and the blockchain.

This allows you to interact with decentralized applications (DApps) without running a full node or knowing how to read code written in Solidity.

How Does MetaMask Work?

MetaMask is a browser extension that lets you interact with the Ethereum network without running a full node. It’s a bridge that allows you to visit the distributed web of tomorrow in your browser today. MetaMask injects the Ethereum web3 API into every website’s javascript context, allowing DApps to read from and write to their contract on your behalf.

How Does MetaMask Work? 

Crypto Storage

MetaMask is a browser extension that allows you to interact with the Ethereum blockchain. It stores your private keys in the browser and allows you to sign transactions securely. It also provides an easy-to-use interface for accessing decentralized applications (dApps).

Your private key will be stored locally on your machine but never transmitted anywhere else. Other people use your public key to send funds to you; however, only people who know your public key and the private key would be able to spend any funds sent to that address.

The reason why we use this system instead of something like traditional bank accounts is that banks are centralized institutions. Meaning all transactions must go through them first before being verified by miners/validators, on top of being censored by governments if necessary.

Token Swaps

Once you have MetaMask installed, you can start trading tokens on the Ethereum blockchain. To do this, you first need to set up a token swap exchange by creating a smart contract on the Ethereum blockchain.

Here’s how it works:

  • You deposit some ETH into your MetaMask account and then send it over to the bankroll address of your newly created token swap exchange smart contract. This will act as collateral for all trades on this particular exchange (allowing users to trade with confidence that their funds are safe).
  • Once it’s been deposited into their account, they can place bids/asks or make trades directly between themselves and other users of their new token swap exchange.

Access to Dapps

MetaMask is a bridge that allows you to visit the distributed web of tomorrow in your browser today. Furthermore, it allows you to run Ethereum dApps in your browser without running a full Ethereum node. As a result, you can safely transfer and receive funds and interact with smart contracts on the Ethereum blockchain.

MetaMask includes a secure identity vault, providing a user interface to manage your identities on different sites and sign blockchain transactions. The mask also gives apps access to local file systems such as temporary files, cookies, local storage, and more.

What advantages does MetaMask have?

MetaMask bridges the web and the blockchain, allowing you to use Ethereum without running a full node. Instead, it acts as your identity on the blockchain, giving you an address to send and receive digital tokens, including LUNC coins, sign transactions, and interact with various smart contracts.

Because it’s just an extension of Chrome or Firefox, MetaMask doesn’t require any installation or setup. Instead, you install it from its website (either in Chrome or Firefox) and then import your existing wallet – that’s it! So as long as you’re using MetaMask for all your transactions with Dapps, your private key will be kept safe from prying eyes.

How to get started using MetaMask

Setting up MetaMask is easy. Once you’ve downloaded the app and installed it, the very first thing you should do is create a new account.

To do this, click “Create Account” in the top right corner of your screen. You will then be prompted to enter a password for your new account. Make sure you use a strong password (at least 12 characters long) and store it safely, as this information cannot be recovered if lost/forgotten!

After creating an account and storing your wallet file locally on your computer or device (if desired), you must add an Ethereum address to send tokens from so that others can send them to you.

You can add one now by typing in its name into the search bar at the bottom of your screen; mine was called ‘MyEtherWallet’ (this may vary depending on how many accounts have been added).

Clicking this address will reveal two sections: ‘Address’ and ‘View key’; click each one in turn so that there are two boxes for each one filled out with information about what they are doing there. Finally, click ‘Save Changes & Go To MyEtherWallet App’ to save these changes into metamask.
