MetaMask is a leading self-custody cryptocurrency wallet available as a browser extension and mobile app. It enables users to securely store, send, receive, and manage digital assets across various blockchain networks while seamlessly interacting with decentralized applications (dApps). Whether you're entering the world of decentralized finance (DeFi), non-fungible tokens (NFTs), or other Web3 services, MetaMask serves as your gateway to the blockchain ecosystem.
This guide provides a clear, step-by-step walkthrough for installing and configuring your MetaMask wallet, ensuring you can safely and confidently begin your journey into Web3.
Choosing Your Browser and Installing MetaMask
To use MetaMask on desktop, you’ll need a compatible browser. Supported options include Google Chrome, Brave, Firefox, and other Chromium-based browsers.
- Visit the official extension store for your browser (e.g., the Chrome Web Store for Chrome/Brave or the Firefox Add-ons site for Firefox).
- Search for "MetaMask."
- Click "Add to Browser" and confirm the installation.
For mobile users:
- iOS: Download the MetaMask app from the App Store.
- Android: Download the MetaMask app from Google Play.
Creating Your New Wallet
Once the extension is installed, click its icon (typically a fox face) in your browser's toolbar.
- You will be greeted with a splash screen. Click "Get Started."
- On the next screen, select "Create a Wallet."
- You will be asked if you want to help improve MetaMask by sharing anonymous usage data. You can choose "No Thanks" or "I Agree" based on your preference.
- You will now be prompted to create a strong password.
Creating a Strong Password
Your password encrypts your wallet data on this specific device. While it's important, it is not the master key to your funds.
- Use a minimum of 8 characters, but aim for a longer, more complex passphrase.
- Incorporate a mix of uppercase letters, lowercase letters, numbers, and symbols.
- Avoid using personal information or common words.
- Consider using a reputable password manager to generate and store a strong, unique password.
After creating and confirming your password, read and agree to the Terms of Use to proceed.
Securing Your Secret Recovery Phrase
This is the most critical step in securing your crypto assets. Your Secret Recovery Phrase (SRP) is a 12 to 24-word sequence that represents the master key to your entire wallet and all accounts within it.
- Whoever has this phrase has complete control over your funds.
- This is the only way to restore your wallet if you lose access to your device or forget your password.
- MetaMask or any legitimate support team will never ask for your Secret Recovery Phrase.
How to Back Up Your SRP Securely
- MetaMask will display your unique SRP. Write down each word clearly and in the correct order on a piece of paper or a dedicated metal backup tool.
- Confirm your phrase by selecting the words in the correct sequence when prompted.
- Store this written copy in multiple secure, offline locations, such as a safe or a safety deposit box. Do not store it as a screenshot, in a text file, or in an email.
Warning: Never share your Secret Recovery Phrase with anyone. It is the ultimate key to your cryptocurrency wallet.
Configuring Blockchain Networks
By default, MetaMask is set to the Ethereum Mainnet. However, it is compatible with any Ethereum Virtual Machine (EVM) network, such as Polygon, Avalanche, Fantom, and many others.
How to Add a New Network
You will often need to add a network manually to interact with its dApps and assets.
- Open your MetaMask wallet.
- Click the network dropdown menu at the top (it likely says "Ethereum Mainnet").
- Select "Add network."
You will need to enter the correct network details. These can typically be found on the blockchain project's official website or documentation. Essential details include:
- Network Name
- New RPC URL
- Chain ID
- Currency Symbol
- Block Explorer URL
- After entering the information, click "Save."
The new network will now be available in your dropdown list. You can switch between networks at any time, as each has its own unique native currency and token balances.

Understanding Your Wallet Interface
After setup, your main wallet view will show several key pieces of information:
- Account Name: Your first account is named "Account 1" by default. You can create more accounts later.
- Public Address: This is your unique public identifier—a long string of letters and numbers. You share this address to receive funds. Click the copy icon next to it to easily share it.
- Assets Tab: This section displays the balance of the native coin and any other tokens you hold on the currently selected network.
- Activity Tab: This log shows the history of your incoming and outgoing transactions.
Importing Tokens to Your Wallet
New wallets will only automatically显示 the native currency (e.g., ETH on Ethereum, MATIC on Polygon). To view other tokens (like USDC, SHIB, or any other ERC-20 token), you must import them.
- Ensure you are on the correct network for the token.
- In the "Assets" tab, scroll down and click "Import tokens."
You will need the token's contract address. The safest way to find this is on a reliable data aggregator like CoinMarketCap or CoinGecko.
- Search for the token on one of these sites.
- On the token's page, find the contract address and copy it.
- Paste the contract address into the field in MetaMask. The other details (token symbol, decimals) should auto-populate.
- Click "Add Custom Token" and then "Import Tokens."
The token and your balance will now be visible in your Assets list.
Connecting to Web3 Websites
A core function of MetaMask is interacting with dApps, NFT marketplaces, and DeFi protocols.
- Navigate to a Web3-enabled website.
- Look for a "Connect Wallet" button (common labels include "Connect," "Connect Wallet," or "Sign In").
- Clicking it will typically trigger a MetaMask pop-up asking you to connect your wallet.
- Review the connection request carefully, ensuring you trust the site.
- Select the account you wish to connect and click "Confirm" or "Connect."
A connected indicator will often appear on the site. Remember, connecting your wallet only shares your public address; it does not give the site access to your funds or private keys.
Making Your First Transaction
Acquiring Gas Fees
To perform any on-chain action (sending funds, swapping tokens, interacting with a dApp), you must pay a network fee, known as a "gas fee," in the network's native currency.
- How to get native currency: You can purchase it directly through MetaMask's "Buy" button using a debit card, credit card, or bank transfer via integrated third-party services. Transfers are not instant and may take several minutes.
Sending Crypto
- In your MetaMask wallet, click the "Send" button.
- Paste the recipient's public wallet address into the field. Always double-check this address, as transactions are irreversible.
- Select the asset and enter the amount you wish to send.
- Click "Next" and review the transaction details, including the estimated gas fee.
- If everything is correct, click "Confirm" to broadcast the transaction to the network.
You can track its progress in the "Activity" tab. 👉 View real-time tools for tracking transaction status
Frequently Asked Questions
Is MetaMask free to use?
Yes, downloading and using the MetaMask wallet is completely free. However, you will always need to pay blockchain network gas fees for transactions like sending crypto or interacting with smart contracts. These fees are paid to network validators, not to MetaMask.
What happens if I uninstall the extension or lose my phone?
As long as you have your Secret Recovery Phrase (SRP), you can recover your entire wallet with all its accounts and transaction history. Simply reinstall MetaMask on any device and choose the "Import using Secret Recovery Phrase" option. Without the SRP, your funds cannot be recovered.
Can I use one MetaMask wallet for multiple blockchains?
Absolutely. MetaMask supports all EVM-compatible chains. Your public address remains the same across these networks, but the assets and balances are separate. You must add each network (like Polygon or Binance Smart Chain) manually and hold that network's native currency for gas fees.
Is it safe to connect my wallet to any dApp?
You should only connect your wallet to websites you trust. While connecting is generally safe and only shares your public address, malicious sites can create harmful transaction requests. Always carefully review every transaction pop-up from MetaMask before confirming.
Why can't I see my tokens after sending them to my address?
First, confirm the transaction was successful using a block explorer. If it was, you are likely on the wrong network in MetaMask. Switch to the correct network that the token exists on. If you are on the right network, you may need to manually import the token using its contract address to make it visible.
Can I buy cryptocurrency directly within MetaMask?
Yes, MetaMask offers a "Buy" feature through integrated third-party service providers like Transak. This allows you to use traditional payment methods to purchase crypto directly into your wallet, though availability depends on your region.
