MetaMask Extension

Secure Browser Wallet for Ethereum and Web3 Assets

What Is MetaMask Extension?

MetaMask is a popular browser extension wallet that enables users to securely manage Ethereum, ERC-20 tokens, and other Web3 assets. It serves as a bridge between your web browser and decentralized applications (dApps), allowing seamless interaction while maintaining self-custody of private keys.

Unlike centralized exchange wallets, MetaMask gives users full control over their crypto assets. Your private keys are stored locally in the browser extension and encrypted with a password. For enhanced security, MetaMask can also integrate with hardware wallets like Ledger and Trezor.

Never share your MetaMask seed phrase. Keep it offline and secure to protect your assets.
