01 / THE BASICS
Start with a clearer picture of what a wallet actually does.
A wallet doesn’t hold your crypto.
It holds the keys.
MetaMask is a browser-based cryptocurrency wallet that helps people interact with supported blockchain networks and decentralized applications. It gives you an interface for managing accounts, reviewing assets, and approving transactions.
Digital assets are recorded on their blockchain networks—not stored as files inside your browser. Your wallet manages the cryptographic credentials used to authorize actions. Think of it as a keyring and a window into Web3, not a bank account.
Before you approve anything: check the permissions, destination address, network, amount, and applicable fees. A confirmed blockchain transaction may be irreversible.
A SIMPLE MENTAL MODELYour browser is
Your browser is
the bridge.
A wallet connects you to compatible websites. You stay in control of whether a request gets approved.

Anyone who gets your recovery phrase or private keys may be able to control the associated wallet.
Keep recovery information private
Never share your Secret Recovery Phrase or private keys—not with a person, website, or supposed support agent.
Verify every website
Check domain names carefully. Avoid suspicious links sent through email, messaging apps, or social media.
Read before you sign
Understand the transaction details, destination, network, and fees before approving a request.
Review connected apps
Check token approvals and application permissions. Revoke access you no longer need when appropriate.
Secure your device
Keep your browser and operating system current, use a strong device password, and install software from trustworthy sources.
Ignore fake support
Legitimate support should never ask you for your recovery phrase or private keys.
!
Recovery phrase = full access. Never enter it into a website claiming to verify, sync, or unlock your wallet. Use official support resources if you need help.

Web3 is a developing ecosystem of applications that use blockchain technology for digital asset transfers, decentralized exchanges, blockchain gaming, and digital ownership. A compatible wallet can be your interface to these services.
But a connection isn’t an endorsement. Malicious applications may seek excessive permissions or encourage harmful signatures. Research unfamiliar projects independently, read prompts carefully, and avoid financial decisions based only on promotional claims or online recommendations.
