Your Gateway to Secure Crypto Wallet Management and Web3 Access

Introduction

The MetaMask Extension is one of the most popular browser-based cryptocurrency wallets, enabling users to store, send, receive, and manage digital assets securely.

What Is the MetaMask Extension?

The MetaMask Extension is a browser add-on that functions as a non-custodial crypto wallet.

Unlike traditional wallets, MetaMask does not store user data or control funds, ensuring complete ownership of digital assets.

The extension supports Ethereum and multiple Ethereum Virtual Machine (EVM) compatible networks, making it versatile and widely compatible.
