MetaMask Wallet: The Leading Self-Custody Crypto Wallet for Web3

MetaMask is one of the world’s most popular self-custody cryptocurrency wallets, trusted by over 100 million users for secure, decentralized, and user-friendly management of digital assets. Originally built for the Ethereum blockchain, MetaMask now supports a wide range of Ethereum Virtual Machine (EVM)-compatible networks, making it a versatile gateway to the decentralized web and the broader world of Web3.

What Is MetaMask?

MetaMask is a non-custodial wallet, meaning you—and only you—control your private keys and digital assets. Available as a browser extension and a mobile app, MetaMask acts as a bridge between your device and blockchain networks. It allows you to store, send, receive, and swap cryptocurrencies and tokens, as well as interact directly with decentralized applications (dApps) across DeFi, NFTs, gaming, and more.

Core Features

1. Self-Custody and Security

• Your private keys and recovery phrase are generated and stored locally on your device, never on MetaMask’s servers.
• Security features include end-to-end encryption and a unique seed phrase for wallet recovery.
• As a hot wallet, MetaMask is always connected to the internet, so users must remain vigilant against phishing attacks and never share their recovery phrase.

2. Multi-Network and Token Support

• Manage Ethereum (ETH), ERC-20, and ERC-721 tokens, as well as assets on other EVM-compatible networks like Polygon, BNB Smart Chain, Optimism, and Arbitrum.
• Add custom networks and tokens, and switch between mainnets and testnets for development or experimentation.

3. dApp and Web3 Integration

• Connect seamlessly to thousands of dApps: trade on decentralized exchanges, mint NFTs, play blockchain games, and access DeFi protocols.
• The built-in dApp browser on mobile makes exploring Web3 easy and secure.

4. Built-In Swaps and Purchases

• Swap tokens directly within MetaMask using decentralized exchange aggregators for the best rates.
• Buy crypto with credit cards, bank transfers, or PayPal (where supported), and receive assets directly in your wallet.

5. Portfolio and Transaction Management

• Track your digital assets and transaction history in a unified dashboard.
• Customize transaction fees and speeds, leveraging Ethereum’s EIP-1559 for more predictable gas costs.

6. Advanced Features

• Integrate with hardware wallets like Ledger or Trezor for enhanced security.
• Stake supported assets, bridge tokens between networks, and manage privacy settings and permissions.
• Perform crypto tax reporting directly from your MetaMask Portfolio with integrated partners.

How MetaMask Works

• Setup: Install the browser extension or mobile app, create a wallet, and securely store your 12-word recovery phrase.
• Wallet Management: Generate multiple Ethereum addresses, manage tokens, and interact with dApps—all from a single interface.
• Transactions: Initiate transfers, swaps, or dApp interactions; every action requires your explicit confirmation, and transactions are signed locally using your private key.
• Network Customization: Add and switch between EVM-compatible networks, enabling access to various blockchain ecosystems.

Safety and Best Practices

• MetaMask never stores your private keys or recovery phrase on its servers; you are responsible for safeguarding them.
• Always verify you are using the official MetaMask website or app to avoid phishing scams.
• Never share your recovery phrase—anyone with access to it can control your wallet and funds.
• Consider pairing MetaMask with a hardware wallet for large balances or long-term storage.
