MetaMask Wallet Installation

MetaMask is a self-custodial wallet provider supporting transactions in web3. It's how you interact with the blockchain from inside your web browser (including to check token balances in your account)

What are Wallets?

Key manager used to manage your cryptocurrencies or tokens
Authorize transactions and interact with web pages or decentralized applications
Subscribe to messages demonstrating that you own a wallet address

Never share your private keys, or mnemonic phrase. If someone has your private key, they are able to perform transactions on your behalf; to include spending your tokens.

What is MetaMask?

Available as a browser extension and as a mobile app, MetaMask equips you with a key vault, secure login, token wallet, and token exchange—everything you need to manage your digital assets.

Installation

To install MetaMask in your browser (we will be using chrome for the exercise), navigate to metamask.io and select Download

Select the option to download the browser extension

You will be redirected to the Chrome browser webstore where the extension can be added to your browser

You will need to Accept the MetaMask Permissions and Add the extension

Once downloaded and installed you will see the MetaMask Fox Logo in your extensions popup

If you want to add MetaMask to always be visible, click the Pin Icon to the left of the Kabab Button. This will make MetaMask easily accessible for the rest of the exercise. You can toggle this off if you want to revert it later

If you already have a Wallet (private key or mnemonic phrase) you can Import an Existing Wallet. Otherwise we will be creating a new wallet for this exercise

Note: While you should not be using your main wallet for this exercise, or while you are learning, you are able to connect a hardware (cold storage) wallet to MetaMask by Following the tutorial found here: https://www.youtube.com/watch?v=uI2NpkiUKsQ

Testnet and Faucets

In blockchain technology, a testnet is an instance of a blockchain powered by the same or a newer version of the underlying software, to be used for testing and experimentation without risk to real funds or the main chain. Testnet coins are separate and distinct from the official (mainnet) coins, don't have value, and can be obtained freely from faucets.

Creating a 2nd account

You can add another address to your wallet by highlighting the down carrot

Select the add account button

Select "Add a new account"

Give your wallet a name that you can identify, and then select select create

You can now transact with yourself if you want!
