MetaMask has become an essential tool for anyone exploring the world of Web3. Whether you're trading NFTs, engaging in DeFi (decentralized finance), or playing blockchain games, MetaMask serves as your gateway to the decentralized ecosystem. As one of the most popular cryptocurrency wallets, it allows users to seamlessly switch between various Ethereum-compatible networks with ease.
In this comprehensive guide, we’ll walk you through setting up and using MetaMask on both mobile and PC, complete with clear instructions and visual references. You’ll learn how to create a wallet, deposit and send crypto, connect to DApps, manage network settings, and more—all while prioritizing security and usability.
Getting Started with MetaMask: Setup for PC and Mobile
Before diving into transactions or DApp interactions, you need to install MetaMask. The wallet is available across platforms:
- PC: As a browser extension for Chrome, Firefox, Brave, Edge, and Opera.
- Mobile: Native apps for iOS and Android.
Both versions are free and offer nearly identical functionality. Let’s begin with setting up your wallet.
Creating a Wallet (Mobile Version)
To install MetaMask on your smartphone:
- Download the app from the App Store (iOS) or Google Play (Android).
- Open the app and tap "Get Started".
- Select "Create a New Wallet".
- Review the privacy policy and terms, then proceed to set a password.

Security Tips During Setup
- Choose a strong password: at least 12 characters long, combining uppercase, lowercase, numbers, and symbols.
- Avoid common patterns like birthdays or keyboard sequences.
- Never reuse passwords from other services.
- Enable biometric authentication (Face ID/Touch ID) if supported.
After setting your password, MetaMask will display your Secret Recovery Phrase—a sequence of 12 English words that acts as your wallet’s master key.
🔐 Critical Reminder: Write down your recovery phrase and store it offline in a secure location. Never share it with anyone or save it digitally (e.g., screenshots, cloud storage).
You’ll be asked to confirm the phrase by selecting the words in order. Once verified, your wallet is ready to use.
Creating a Wallet (PC Version)
Setting up MetaMask on desktop:
- Visit the official website and download the extension for your browser.
- Click "Add to Chrome" (or your preferred browser).
- After installation, click "Get Started", then choose "Create a New Wallet".
- Accept the terms and create a secure password.
The process continues just like on mobile: you’ll be guided to view and verify your Secret Recovery Phrase.
Click "Secure Wallet", reveal the phrase, write it down safely, and re-enter it to confirm.
Once confirmed, your PC wallet is active and ready.
Key Security Notes
- Recovery Phrase = Full Access: Anyone with your phrase can take full control of your funds.
- No Recovery Option: Unlike traditional accounts, there’s no “forgot password” option—your phrase is the only backup.
- Store it physically: Use a metal backup or handwritten note stored in a safe place.
Using MetaMask: Deposit, Send, Connect & Track
Now that your wallet is set up, let’s explore its core functions.
How to Deposit Cryptocurrency into MetaMask
To receive funds (like ETH or other ERC-20 tokens):
- Open MetaMask (mobile or PC).
- Tap or click the account address shown at the top (starts with
0x...). - Select "Copy" to copy your public address.
Next:
- Log in to your exchange (e.g., Binance, Coinbase, Kraken).
- Navigate to Withdraw > Ethereum (ETH) or compatible token.
- Paste your MetaMask address.
- Confirm withdrawal (some exchanges require email/SMS verification).
⏳ Note: Deposits may take several minutes depending on network congestion and gas fees.
Ensure you're withdrawing on the correct network (e.g., Ethereum Mainnet, Polygon). Mismatched networks can result in lost funds.
Sending Crypto from MetaMask
To send cryptocurrency:
- In MetaMask, click "Send" (PC) or "Send" button on mobile.
Paste the recipient’s wallet address.
- ✅ Use copy/paste or scan QR code to avoid typos.
- Enter the amount and select the token.
- Review gas fee (transaction cost) based on current network load.
- Click "Confirm" to complete the transaction.
You can adjust gas fees manually under advanced options—lower fees mean slower confirmation.

Switching Between Blockchain Networks
MetaMask supports multiple Ethereum-compatible chains such as:
- Ethereum
- Polygon
- BNB Chain
- Arbitrum
- Avalanche
- Base
- zkSync Era
By default, MetaMask shows Ethereum Mainnet. To switch:
- Click the network dropdown (top center).
- Select a preloaded network like Polygon.
- If not listed, click "Add Network" > choose from popular options or add manually via RPC settings.
Each network operates independently—your ETH balance on Ethereum doesn’t carry over to Polygon unless bridged.
Connecting MetaMask to DApps
One of MetaMask’s greatest strengths is its integration with decentralized applications (DApps). Examples include:
- Uniswap / SushiSwap / PancakeSwap – Swap tokens
- OpenSea / tofuNFT – Buy/sell NFTs
- Axie Infinity – Play-to-earn games
- DeFi dashboards – Track portfolio performance
Example: Connecting to OpenSea
- Go to OpenSea.io.
- Click "Log In" > select "MetaMask".
- Your wallet will prompt you to sign a connection request.
- Approve it.
Now you can browse, buy, sell, and manage NFTs directly using your MetaMask wallet.
🛡️ Only connect to trusted DApps. Phishing sites may attempt to steal your credentials.
If you accidentally connect to a malicious site, use Revoke.cash or MetaMask’s permission management to revoke access.
Monitoring Transactions in MetaMask
All activity—deposits, sends, swaps—is recorded in your transaction history.
- PC: Click the Activity tab.
- Mobile: Tap the clock icon at the bottom.
Each entry shows:
- Transaction type
- Status (pending/confirmed)
- Amount
- Gas fee
- Timestamp
For deeper insights:
- Click "View on Block Explorer" to see full details on Etherscan or similar platforms.
- Export data for tax reporting or financial tracking.
Frequently Asked Questions (FAQ)
Q1: Is MetaMask safe to use?
Yes, when used correctly. Since it's a non-custodial wallet, only you control your keys. Just ensure you never share your Secret Recovery Phrase and verify all DApp connections.
Q2: Can I use MetaMask on multiple devices?
Yes. Install MetaMask on another device and restore using your 12-word recovery phrase. Do not share this phrase across devices electronically.
Q3: What happens if I lose my recovery phrase?
Unfortunately, there is no way to recover your wallet without it. Always store it securely offline.
Q4: Why do I need gas fees?
Gas fees pay miners/validators to process transactions on blockchain networks like Ethereum. Fees vary based on network demand.
Q5: Can I swap tokens inside MetaMask?
Yes! MetaMask includes a built-in swap feature that compares rates across decentralized exchanges (DEXs) like Uniswap and SushiSwap.
Q6: How do I revoke permissions from a DApp?
Go to MetaMask Settings > Security & Privacy > Connected Sites > Revoke Access, or use third-party tools like Revoke.cash.
