What Is MetaMask Chrome Extension?

MetaMask is a browser extension that functions as a self-custody wallet for Ethereum and other EVM-compatible networks. Once added to your Chrome browser, it gives you full control of your funds, enabling direct interaction with the Ethereum blockchain without needing centralized exchanges or platforms.

It supports ETH, ERC-20 tokens, and a wide range of decentralized applications. With MetaMask, your private keys are stored locally and encrypted, ensuring you stay in full control of your assets at all times.
