MetaMask Chrome Extension

Easily manage your Ethereum wallet, explore dApps, trade tokens, and interact with Web3 securely from your browser.

Overview

The MetaMask Chrome Extension is one of the most widely used tools in the Web3 ecosystem. It serves as a digital wallet for Ethereum and other EVM-compatible networks, enabling users to store, send, receive, and swap tokens. More importantly, MetaMask acts as a bridge between your browser and decentralized applications (dApps), giving you full control of your private keys and transactions.
