Ethereum and public blockchains represent the next evolution of internet databases, while MetaMask is pioneering the future of web browsers.
As a browser extension and mobile app, MetaMask serves as a secure Ethereum wallet, enabling you to manage private keys, store ETH/tokens, and interact seamlessly with decentralized applications (dApps). Unlike custodial wallets, MetaMask empowers true self-custody—it never stores your email, passwords, seed phrases, or private keys.

Understanding Extension Permissions
MetaMask requires permission to “read and change site data” because it injects a Web3 JavaScript object into pages. This:
– Enables dApp connectivity
– Doesn’t alter website content
– Follows standard extension protocols
For added security:
– Use a dedicated browser profile
– Review permissions periodically
Funding Your Wallet
Three ways to add crypto assets:
- Credit/Debit Card: Buy directly via MetaMask’s fiat on-ramp
- Transfers: Receive tokens from other wallets
- Exchange Deposits: Send crypto from platforms like Coinbase or Binance
