How to use MetaMask: A Complete Guide

MetaMask! A familiar name in the web3 and crypto space. As you may already know, Metamask is one of the most popular Ethereum wallets, functioning as a bridge between standard web browsers and the Ethereum blockchain (including Ethereum-compatible chains like Polygon, BSC, etc.). 

With MetaMask, you can interact with decentralized applications (DApps), manage your Ethereum (ETH) and Ethereum-based tokens, and handle transactions. 

This guide will help you understand how to set up and use MetaMask as a regular user and a developer on Bunzz

Let’s get started! Shall we? 

Installing MetaMask

For Browsers:

1. Choose Your Browser: MetaMask is available as an extension for Chrome, Firefox, Brave, and Edge.

2. Visit the Official Site: Go to the MetaMask website.

3. Download: Click on the “Download” button, and you’ll be directed to the extension page of your browser.

4. Install: Click “Add to Chrome” (or the equivalent button for your browser) and then “Add Extension”.

For Mobile:

MetaMask also offers a mobile app for iOS and Android. Simply search for “MetaMask” in your app store and download it.

How to use MetaMask

Setting Up Your Wallet:

1. Open MetaMask: Click on the MetaMask fox icon in your browser extensions bar.

2. Create a Wallet: If you’re a new user, click “Get Started”. Then, select “Create a Wallet”.

3. Backup Your Secret Recovery Phrase: You’ll be shown a 12-word recovery phrase. This is vital for recovering your wallet, so write it down securely.

4. Set a Password: Choose a strong password for accessing MetaMask on your browser.

Transferring and Managing ETH and Tokens

1. Receiving Ethereum: Click on your account name at the top to copy your address. Provide this to anyone sending you Ethereum or tokens.

2. Sending Ethereum: Click “Send”, paste the recipient’s Ethereum address, set the amount, and confirm.

3. Adding Tokens: For tokens based on Ethereum, click “Add Token,” search or input the token contract address, and confirm.

Note: MetaMask isn’t limited to Ethereum Mainnet. You can connect to testnets or other Ethereum-compatible networks by selecting the network dropdown at the top.

Interacting with DApps

You can seamlessly interact with DApps using MetaMask in the following ways:

1. Connect to a DApp: When you visit a DApp website, it may request to connect to your MetaMask. Grant permission if you trust the DApp.

2. Make transactions: While using a DApp, you may need to perform certain actions on the DApp; when required, MetaMask will prompt you to confirm transactions.

While interacting with DApps, you must be security conscious. These are basic and common security measures you can take:

  1. Never share your recovery phrase. Anyone with this phrase can access your funds.
  2. Ensure you have multiple secure backups of your recovery phrase.
  3. Always verify and double-check the address when sending funds.
  4. Ensure your MetaMask extension or app is always updated with the latest security features.

PS: If a token isn’t listed, you can add it manually using its contract address. When sending ETH or interacting with DApps, you can adjust gas fees based on urgency.
