For account-specific help, use the official MetaMask Support Center.
What is the MetaMask browser extension?
MetaMask is a self-custodial wallet extension that helps people interact with supported blockchain networks and decentralized applications from a desktop browser. It is a software wallet, not a bank account or a guarantee against loss.
Is MetaMask available in every browser?
Availability can change over time. Check the official MetaMask download page for current supported browsers and platforms, and install only from a verified official listing.
Does connecting my wallet approve a transaction?
Connecting typically shares a public wallet address with the dapp. It is different from approving a transaction or signing a message. Review what a dapp requests and only approve actions you understand.
What should I do with my Secret Recovery Phrase?
Store it privately in a secure offline place. Never share it with anyone, enter it into a website or support chat, or store it in an untrusted app. Anyone who has it may control the wallet.
