How to install MetaMask in your web browser
There are many different cryptocurrency wallets out there, but Metamask is incredibly popular. It’s simple and versatile. You can use it for NFTs, buy and sell tokens on decentralized exchanges (DEX), or access a plethora of DeFi applications (dApps).
MetaMask can be installed as an extension in your web browser or downloaded to smartphones (iPhone and Android) as an app. You will need Google Chrome, Mozilla Firefox, Brave or Microsoft Edge to use it in a browser. To get started, go to MetaMask download page.
For this explainer, Chrome will be used as the browser. If you are using Firefox, the download and installation steps are very similar. Once installed, MetaMask works the same regardless of browser.
Once on the download page, click “Install MetaMask for Chrome” (or your browser of choice.)
A new tab should open and direct you to the Chrome Web Store. There will be an option in the upper right corner to install MetaMask. Click “Add to Chrome”.
A new page will open. Click the “Start” button.
Now you will click on “Create Wallet”. If you already have a wallet, select the “Import Wallet” option.
If you have downloaded MetaMask on your phone, you can use the “Import Wallet” to integrate the wallet between your computer and your phone. You can do the same if you want to use Metamask across multiple browsers on different computers.
The next page will ask you if you want to accept the MetaMask User Agreement. Either option can be selected to continue.
Now you will create a password for your wallet. Make sure you agree to the Terms of Service. Your password will need to be entered each time MetaMask is used through the browser.
You will now have access to your backup passphrase. Your backup passphrase is the most important piece of information.
Warning: Don’t lose or forget your backup passphrase. If you forget your password, your backup passphrase is the only way to access your wallet. If someone else knows your passphrase, they can access your wallet.
Write down your backup passphrase on a piece of paper. Do not store them on your computer. Make sure you always know where your backup passphrase is saved.
Click on the box that says “Click here to reveal the secret words”. Write down your backup passphrase.
After writing down your backup passphrase, click on the words in the order they appeared and click “Confirm”.
And There you go. You have now created a MetaMask wallet. You can view your account balance, buy and send Ethereum, and view recent activity.
In the future, if you want to open the MetaMask wallet in your browser, click on the fox in the upper right corner. If you don’t see the fox, click on the puzzle piece to the right and it should be available.
Now that you have a MetaMask wallet, you can interact with all kinds of dApps, buy NFTs or send and receive Ethereum.
Regardless of the app you’re interacting with, you’ll usually see a prompt to “Connect Wallet” or something similar. There are different ways for dApps to say this, but by clicking on it, you will be able to transact seamlessly with just a few clicks.
Warning: Make sure that the app or platform you are going to connect your wallet to is trustworthy. If in doubt, take the extra time to do a little research. Most importantly, do not provide your passphrase to any platform, email, or person. All your assets can be stolen if obtained.
Once you have clicked on the “Connect Wallet” button, you will be prompted to select the wallet you wish to connect. A Uniswap interface is shown below as an example. You can see the “Connect to Wallet” button on the top right. When you click on it, a few options appear. Click on MetaMask and your MetaMask wallet is now connected to the app.
