MetaMask Extension is a browser-based tool that connects your desktop browser with Web3 applications and supported blockchain networks. It makes it easier to interact with decentralized applications, review transaction requests, and manage blockchain accounts directly from your browser.
MetaMask is available as an extension for Chrome, Firefox, Brave, Edge, and Opera.

Connection with supported decentralized applications
Transaction signing and approval

Once installed from an official source, MetaMask adds an icon to your browser. When you visit a compatible Web3 application, the extension can provide connection and transaction requests for you to review.
Before approving an action, users should carefully check what they are signing and make sure the website is trustworthy.
Security is especially important when using self-custody services. Your Secret Recovery Phrase (SRP) should never be shared with another person or entered into an unfamiliar website. MetaMask states that anyone with access to the SRP can control the associated accounts and assets.
Always:
Download MetaMask from the official website or official browser store.
Check the website address before entering sensitive information.
Never share your Secret Recovery Phrase or private keys.
Avoid suspicious links and unknown browser extensions.
Keep your browser and MetaMask software updated.
Review transaction details before approving them.
MetaMask specifically recommends obtaining the extension through its official download page or recognized browser extension stores.
Which browsers support MetaMask Extension?
MetaMask currently lists Chrome, Firefox, Brave, Edge, and Opera as supported browsers for its extension.
Is MetaMask Extension free?
The extension itself can be installed without a purchase, although blockchain transactions may involve network fees.
Is MetaMask Extension safe?
It can be used securely when obtained from an official source and combined with strong security practices. However, users remain responsible for protecting their Secret Recovery Phrase and approving transactions carefully.
What happens if I lose my Secret Recovery Phrase?
For a self-custody setup, MetaMask cannot recover the phrase for you. Losing it can mean losing access to the associated accounts and assets.
MetaMask Extension provides a convenient way to bring Web3 functionality into a desktop browser. Its simple interface and dApp connectivity make it useful for users exploring blockchain-based applications.
The most important principle is security first: download only from official sources, protect your Secret Recovery Phrase, and never approve an unfamiliar request without checking it carefully.
