What is MetaMask?

MetaMask is a non-custodial cryptocurrency wallet designed primarily for Ethereum. Unlike centralized exchanges, MetaMask gives users full control of their private keys. This ensures that funds remain completely in your possession, making it a reliable choice for storing digital assets safely.

Additionally, MetaMask serves as a bridge between traditional web browsers and the decentralized web (Web3), enabling seamless interaction with blockchain-based applications. You can explore marketplaces, decentralized finance (DeFi) platforms, and NFTs without leaving your browser.
