How the MetaMask Extension Works

The MetaMask Extension acts as a bridge between your browser and blockchain networks. When you interact with a decentralized application, MetaMask prompts you to approve connections and transactions.

Each transaction is signed locally using your private key, ensuring that sensitive data never leaves your device.

Occasionally, users may experience connection issues due to browser updates or corrupted cache.

Reinstalling the extension or restoring the wallet using the recovery phrase usually resolves these problems.
