Official link included ✓

This guide walks through installing and using the MetaMask Extension, managing accounts, connecting to dApps safely, and protecting your funds. Always confirm downloads using the official MetaMask site.

1

Install the MetaMask Extension

Install from the official site or your browser's extension store. Check the publisher name and reviews — fake extensions can impersonate MetaMask. Prefer installing from metamask.io.

2

Create, import, or connect wallets

Create a new wallet or import an existing one using your recovery phrase only in the extension UI. You can also connect hardware wallets for added security. Never share the recovery phrase. 🗝️

3

Manage multiple accounts and networks

MetaMask supports multiple accounts and custom networks. Name accounts clearly, and add only trusted custom RPCs. Be cautious with unknown networks as they may request token approvals. 🌐

4

Connect to dApps safely

When a dApp requests connection, confirm the requested permissions and the account you’re exposing. Use a separate 'hot' account for dApp interactions and limit approvals to necessary tokens and amounts. 🔗

5

Approve transactions with care

Review contract details, gas fees, and recipients before approving. Consider setting custom gas limits for efficiency and using Etherscan or a contract verifier to inspect unfamiliar contracts. ⚖️

6

Keep extension & browser secure

Regularly update MetaMask and your browser. Remove unused extensions, run malware scans, and avoid using MetaMask on compromised machines. Use a hardware wallet for large balances. 🛡️

Practical checklist — before you start

  • Confirm the extension's publisher and the official site: https://metamask.io.
  • Never paste your seed phrase into web forms, chat apps, or unknown prompts.
  • Use a separate hot wallet for dApps and a hardware wallet for cold storage.
  • Limit token approvals and revoke unnecessary allowances regularly.
  • Backup your recovery phrase offline and store it in multiple secure locations. 🔁
