Best Practices for Using MetaMask
Secure Your Recovery Phrase
Physical Storage: Write down your recovery phrase and store it in a secure location, such as a safe. Avoid storing it digitally to prevent hacking.
Avoid Sharing: Never share your recovery phrase with anyone, and be wary of phishing attempts that ask for it.
