Web3 is changing how people interact with the internet. From decentralised finance (DeFi) to NFTs and on-chain identity, one where you control your assets. To take part and not be left out in this ecosystem, you need a reliable crypto wallet. In this guide, we’ll walk you through how to set up and use MetaMask step by step. Whether you’re a complete beginner or looking to make your first on-chain move, this explainer will get you started safely and confidently.
What is MetaMask, and why do you need it?
MetaMask is one of the most trusted wallets in the blockchain space, with millions of users worldwide. It is a non-custodial crypto wallet, meaning you control your funds. It’s your entry point into the decentralised web. It allows you to:
- Store and manage Ethereum-based (ERC-20) tokens
- Interact with DApps, like Uniswap, OpenSea, or Axie Infinity
- Swap tokens directly within the wallet
- Connect to multiple blockchains like BNB Chain, Polygon, and more
Step 1:
- Go to https://metamask.io
- Click “Download”, then:
- Click on “Get Metamask” If you’re using a desktop. Select the appropriate browser extension (Chrome, Firefox, Brave, or Edge) and click “Add to browser” → confirm the installation.
- If you’re on mobile, you’ll be redirected to the App Store (iOS) or Google Play Store (Android) → click “Install” to download the MetaMask app.
Security Tip: Always download MetaMask from the official website. Avoid third-party links,fake versions are common and can compromise your wallet.
Step 2: Create a New Wallet
- Open the MetaMask extension
- Agree to the terms of use and click “create a new wallet”
- Set a strong password (store it securely)
- Click on ‘reveal secret recovery phrase’, write down your Secret Recovery Phrase (12 words). Don’t take a screenshot, write it offline and store it safely. If you lose this phrase, you lose access to your wallet permanently.
Step 3: Explore the Wallet Interface

You’ll now see your dashboard:
- Account address: Your public wallet address (starts with 0x…)
- ETH balance: This is your native token (Ethereum mainnet)
- Navigation buttons: Send, receive, buy, and swap
By default, MetaMask connects to the Ethereum Mainnet. Metamask now supports Solana, and you can now seamlessly create a Solana wallet. You can also add other networks manually.
Step 4: Add Networks (BNB Chain, Polygon, and so on)

Pro Tips for Beginners
- Always double-check websites before connecting MetaMask
- Use hardware wallets for large funds (Ledger, Trezor)
- Avoid clicking random links in DMs, as Telegram scams arecommon.
- Bookmark important DApps so you don’t land on a phishing site.
