MetaMask

MetaMask is a browser-extension wallet used for managing on-chain assets, signing transactions and connecting to decentralized applications. Official builds are available for Windows, macOS, Android, iOS. This page lists where to get the installer for each platform together with version details; always verify the download domain and file signature before installing. Tips: back up the recovery phrase offline right after installation, never as a screenshot or cloud note. Review approval scopes when connecting to dApps and revoke the ones you no longer use. For large balances prefer a hardware wallet, and keep a separate hot wallet for small interactions. Version numbers and package sizes change with each release; always confirm on the official site.
