🦊 MetaMask Extension – Your Gateway to Web3 and DeFi

The MetaMask Extension is a widely-used crypto wallet and Web3 gateway that operates as a browser extension, allowing users to securely store, send, and receive digital assets, and interact with decentralized applications (dApps) directly from their web browser. Developed by ConsenSys, MetaMask has become one of the most popular tools for navigating the decentralized internet, supporting millions of users worldwide.

Available for browsers like Chrome, Firefox, Brave, and Edge, the MetaMask Extension is essential for anyone looking to explore the Ethereum ecosystem, NFTs, DeFi platforms, and more.

🔐 What Is MetaMask?

MetaMask is a non-custodial crypto wallet, meaning users control their private keys and seed phrase. It supports Ethereum and other EVM-compatible blockchains, enabling users to manage tokens, connect to dApps, and perform blockchain transactions without relying on centralized exchanges or intermediaries.

With MetaMask, users can:

• Create or import a wallet
• Manage multiple Ethereum accounts
• Store ETH and ERC-20 tokens
• Sign blockchain transactions
• Connect to dApps securely
• Interact with smart contracts
• Manage NFTs (ERC-721 and ERC-1155)

💡 Key Features

MetaMask installs as a browser extension in just a few clicks. Users can create a new wallet or import an existing one using a 12-word secret recovery phrase. The onboarding process is beginner-friendly yet powerful enough for advanced users.

✅ Multi-Network Support

While MetaMask is known for Ethereum, it also supports EVM-compatible networks like Binance Smart Chain, Polygon, Avalanche, Arbitrum, Optimism, and more. Custom RPCs can be added to access other networks.
