The world of cryptocurrency and decentralized finance (DeFi) is growing rapidly, and MetaMask Extension is one of the most popular tools to interact with it. This browser extension allows users to securely manage cryptocurrencies, access decentralized apps (dApps), and sign transactions—all directly from their desktop browser.

MetaMask combines convenience and security, making it a go-to solution for both beginners and advanced crypto users.
