Metamask® % Extension - Browser extension - GitBook

MetaMask is an extension for accessing Ethereum enabled distributed applications, or "Dapps" in your browser! The extension injects the Ethereum web3 API .

Getting started with MetaMask is an essential step to access its features and interact with the Ethereum blockchain and decentralized applications (dApps). MetaMask is a cryptocurrency wallet and browser extension that allows you to securely manage your Ethereum-based assets directly from your web browser. Below is a step-by-step guide to help you get started with MetaMask:

Step 1: Install MetaMask Extension

The first step is to install the MetaMask extension in your preferred web browser. MetaMask is compatible with major browsers like Chrome, Firefox, and Brave. To install it, visit the official MetaMask website or go to the respective extension store for your browser. Click on the "Add to Chrome" (or the relevant browser) button to install the extension.

Step 2: Launch MetaMask

After the installation, you should see the MetaMask fox icon in your browser's extensions area. Click on the icon to launch MetaMask.

Step 3: Create a New Wallet or Import an Existing One

If you are a new user, you'll be prompted to create a new wallet. Click on the "Get Started" button, and then choose "Create a Wallet." Follow the instructions to set up your new wallet. During this process, MetaMask will generate a unique 12-word seed phrase for you. Make sure to write down the seed phrase and keep it in a safe place. This seed phrase is essential for wallet recovery, so keep it private and never share it with anyone.

If you already have an existing MetaMask wallet and want to access it on a new device or browser, click on the "Import Wallet" option. Enter your 12-word seed phrase to restore your existing account.

Step 4: Confirm Your Seed Phrase

To ensure you have correctly saved your seed phrase, MetaMask will ask you to confirm it. You'll need to enter the words in the correct order as presented during the wallet creation or import process.

Step 5: Set a Password

Next, you'll be asked to set up a password for your MetaMask extension. This password will be required every time you attempt to access your wallet or perform sensitive actions. Choose a strong and secure password to protect your funds and data.

Step 6: Explore the Interface

Once you have successfully set up your MetaMask wallet and logged in, you'll see the wallet interface. It displays your Ethereum address, account balance, and recent transaction history. You can also access various settings and network options from the interface.

Step 7: Connect to Ethereum Mainnet or Test Networks

By default, MetaMask connects to the Ethereum Mainnet, the live Ethereum blockchain. However, you can also interact with dApps on test networks like Ropsten or Rinkeby. To switch networks, click on the network name at the top of the MetaMask extension and select the desired network.

Step 8: Security and Best Practices

Remember to keep your seed phrase and password secure. Never share them with anyone, and avoid entering them on untrusted websites or platforms. Regularly update your browser and MetaMask extension to ensure you have the latest security features.

In conclusion, getting started with MetaMask involves installing the extension, creating or importing a wallet, confirming your seed phrase, and setting up a password. Once you're set up, you can start managing your Ethereum assets, exploring dApps, and engaging with the decentralized world of blockchain applications. Always prioritize security and follow best practices to protect your digital assets.
