MetaMask Chrome Extension® | DeFi Access™
MetaMask is one of the most popular Web3 wallets that allows users to interact with blockchain networks, decentralized applications (dApps), and decentralized finance (DeFi) platforms directly from their browser. The MetaMask Chrome extension integrates seamlessly with Google Chrome, making it easy to manage crypto assets, NFTs, and interact with Web3 services without needing a standalone application.
What Is MetaMask Chrome Extension?
MetaMask Chrome Extension is a browser-based cryptocurrency wallet that connects you to the Ethereum blockchain and other compatible networks. It acts as a bridge between your browser and the decentralized web.
Unlike custodial wallets, MetaMask is non-custodial, which means you control your private keys and funds. The Chrome extension allows:
- Access to Ethereum-based dApps
- Sending and receiving crypto
- Swapping tokens directly in the wallet
- Managing multiple accounts and networks
- Viewing and interacting with NFTs

Originally built for Ethereum, MetaMask now supports multiple networks, including:
- Ethereum Mainnet
- Binance Smart Chain (BSC)
