What is MetaMask Extension?
MetaMask is the original and most trusted non-custodial cryptocurrency wallet browser extension launched in 2016 by Consensys. With over 100 million active users in 2025, it remains the undisputed leader for interacting with Ethereum and the entire Web3 ecosystem directly from your browser (Chrome, Firefox, Brave, Edge, and Opera).
You stay in complete control of your private keys and assets — MetaMask never holds your funds or data.

Security First – You Are in Control
MetaMask never has access to your funds or private keys. Features include transaction simulation, scam detection, seed phrase encryption, and hardware wallet integration. Always download from the official site and never share your seed phrase.
Important Security & Risk Disclaimer
Cryptocurrency is highly volatile and involves significant risk of loss. MetaMask is a self-custodial wallet — you are solely responsible for your private keys and recovery phrase. Never share your seed phrase with anyone. Always verify you are on the official website (metamask.io) and beware of phishing sites, fake extensions, and scams. MetaMask does not provide financial advice. Do your own research. US residents should comply with all applicable laws and tax obligations.
