Your gateway.

The MetaMask extension helps you interact with blockchain networks from your browser. Whether you’re exploring DeFi for the first time or connecting a hardware wallet, its tools are designed to put you in charge.
Transaction simulation and phishing detection can help you spot potential risks, while support for hardware wallets such as Ledger and Trezor offers another way to manage signing. MetaMask Snaps can extend wallet capabilities. These tools are safeguards—not guarantees—so review every request before you approve it.
