Managing Multiple Networks

MetaMask also supports multiple networks, which is useful for users who want to interact with different blockchains like Binance Smart Chain (BSC), Polygon, and others.

1. Switch Networks:

• In the MetaMask extension, click on the network dropdown at the top of the wallet.
• Select the network you want to interact with. If the network is not available, you can add custom networks manually.

1. Add Custom Networks:

• Click on "Settings" in the MetaMask menu.
• Under “Networks,” click “Add Network” and enter the details for the custom network (such as RPC URL, Chain ID, and Network Name).

Best Practices for MetaMask Security

1. Keep Your Seed Phrase Safe: Never share your seed phrase with anyone. It is the key to your wallet and your assets.
2. Enable Two-Factor Authentication: If possible, use two-factor authentication (2FA) for additional security, especially when using MetaMask with exchanges or dApps.
3. Use Strong Passwords: Always use a strong and unique password to protect your MetaMask wallet.
4. Stay Cautious of Phishing Scams: Always double-check website URLs before entering your seed phrase or wallet details. Never click on suspicious links or emails claiming to be MetaMask support.
