MetaMask Chrome Extension® – Your Gateway to Web3 and Decentralized Finance

Introduction

The MetaMask Chrome Extension® is a popular browser wallet that allows users to securely manage cryptocurrencies, interact with decentralized applications (dApps), and explore the Web3 ecosystem directly from Google Chrome. As a self-custody wallet, MetaMask gives users complete control over their private keys and digital assets without relying on a centralized service.
