How to Use MetaMask (Beginner Guide)
Step 1: Install from the official site
Install MetaMask only from metamask.io or official app stores. Fake extensions and apps are a common way funds are stolen.
Step 2: Create a wallet and secure the seed phrase
MetaMask generates a 12-word secret recovery phrase. Store it offline and never share it or enter it into any website. Anyone with the phrase controls your funds.
Step 3: Add networks and funds
MetaMask supports Ethereum and EVM chains; add networks (e.g. Polygon, Arbitrum) as needed. Fund it by sending crypto from an exchange or using an in-app on-ramp.
Step 4: Connect to dApps carefully
You can connect to dApps like Uniswap to swap tokens. Only connect to trusted sites, review every transaction and token approval, and revoke unused approvals periodically.
Step 5: Harden security
For larger balances, pair MetaMask with a hardware wallet so keys never leave the device. Be alert to phishing — MetaMask support will never ask for your seed phrase.
