Why MetaMask?
MetaMask is a non-custodial wallet that lets you hold your own keys, sign transactions, and connect securely to decentralized applications (dApps). By running as a browser extension and mobile app, it becomes your passport to Web3—managing addresses, sending tokens and NFTs, and interacting with protocols across Ethereum and compatible networks. Its popularity stems from a simple UX, wide dApp support, and a proven security model where you control recovery phrases and permissions. For the definitive download and security resources, always use the official metamask.io portal.

Bookmark the official site: https://metamask.io and only update from there.
Using MetaMask with dApps
Connection flow
When you visit a dApp, it will ask to connect your wallet. MetaMask shows a clear permission prompt listing which account is shared and any requested scopes. Always review the dApp URL, expected network, and the action you’re approving. For swaps, mints, or contract interactions, read the transaction details; if something looks off (unexpected spender, gigantic allowance, or wildly high gas), reject first and verify in the dApp documentation.
Network management
- Add networks via verified chain data or pre-vetted RPCs; avoid random pop-ups.
- Switch networks manually when a dApp suggests it; confirm chain IDs match expectations.
- Use testnets for trials to minimize risk before mainnet actions.

Security Best Practices
Guard your Secret Recovery Phrase
Never type your recovery phrase into any website or share it with anyone claiming to be “support.” Use a hardware wallet integration for larger holdings so private keys never touch an online device. Keep device OS and browsers up to date and consider a dedicated profile for Web3 to reduce cross-site tracking or malicious extensions.
Transaction hygiene
- Verify contract addresses from official sources before interacting.
- Set spending caps (allowances) minimally; periodically revoke unused approvals.
- Use a separate “hot” account for experimentation and a “vault” for long-term assets.

Common Pitfalls & How to Avoid Them
Phishing & imposters
Fake extensions, fake support, and airdrop bait are common. Don’t install from ad links; search engines can show sponsored look-alikes. Type the URL directly or use a saved bookmark to metamask.io (official).
Gas surprises
Busy networks spike gas fees. Check base fees and consider timing transactions during lower activity or using L2 networks.
Recovery reality
Lost recovery phrase = lost wallet. Back up offline and test a recovery on a fresh device with a tiny amount before relying on it.
