To buy NFTs or interact with DeFi, owning a Web3 wallet like MetaMask is mandatory. It acts as both your bank vault and your digital passport. We provide a step-by-step tutorial on setting up MetaMask and maintaining wallet safety.

What is MetaMask?

A software cryptocurrency wallet and browser extension designed to store Ethereum-compatible tokens and sign smart contract transactions.

安装 Tutorial

1. Download from Verified Sources

Avoid Google search ads (which often link to phishing sites). Navigate directly to metamask.io or install via official app stores.

2. Choose a Strong Password

Set a local device password to secure the app interface.

3. Write Down the Recovery Seed Phrase (Critical)

Inscribe the 12-word recovery phrase on paper and store it securely offline. Anyone who accesses these 12 words has full control of your assets.

Secure Connection Best Practices

• Verify URLs Before Connecting: Connecting to malicious phishing clones lets hackers inject bad transactions that drain your wallet (fake Approve calls).
• Revoke Connections Regularly: Disconnect your wallet from websites when you are done trading.
