Overview
MetaMask Wallet is a trusted, non-custodial cryptocurrency wallet and gateway to the decentralized web. It allows users to hold, manage, and transact digital assets directly in their browsers or mobile devices, ensuring full ownership of private keys and secure connection to thousands of Web3 applications.
Core Security Principles
MetaMask Wallet is designed with a privacy-first and security-driven architecture. Private keys are generated locally, encrypted, and never leave the user’s device. With multi-layer encryption, hardware wallet support, and strong recovery options, users maintain total control over their assets at all times.
Self-Custody
Your private keys remain encrypted on your device — MetaMask never has access.

Preview and confirm every transaction before signing on-chain.
