The MetaMask Chrome Extension is a leading non-custodial cryptocurrency wallet that allows users to interact with blockchain networks directly from their Google Chrome browser. It is widely used for managing Ethereum-based assets, accessing decentralized applications (dApps), trading tokens, storing NFTs, and participating in the broader Web3 ecosystem.

MetaMask serves as a secure bridge between your browser and blockchain networks, giving you full control over your private keys and digital assets.

What Is MetaMask?

MetaMask is a self-custody wallet, meaning:

• You control your private keys
• You manage your recovery phrase
• No third party has access to your funds

Unlike exchange wallets, MetaMask does not store your assets on centralized servers. Your keys are encrypted and stored locally in your browser.
