MetaMask

Meet MetaMask

MetaMask is a self-custody wallet for holding digital assets and interacting with blockchain applications. Use it through a browser extension or mobile app, select a supported network, and approve the transactions or application connections you initiate. The wallet keys remain under the user's control.

Token swaps sit alongside additional trading, payment, and money-management services. Developers can build wallet connections, embedded wallets, and programmable accounts into applications. Networks and services vary by interface and region, with each connected service defining its own transaction terms and requested permissions. The wallet gives users a place to review and manage those activities across the supported ecosystem.
