How MetaMask Works

MetaMask generates and stores your keys locally on your device. Your wallet is secured by a Secret Recovery Phrase (SRP). When you connect to a dApp, MetaMask presents clear signing prompts so you can understand and approve every action. You can switch networks, add tokens, and manage NFTs—all in one place.

Core Components

• Secret Recovery Phrase: A 12-word phrase used to back up and restore your wallet. Keep it offline and never share it.
• Accounts & Addresses: Create multiple accounts for different use cases and manage them under one wallet.
• Networks: Easily toggle between Ethereum Mainnet, testnets, and other EVM chains.
• Transactions & Signatures: Transparent prompts help you confirm sends, swaps, and contract interactions.
