Actually, everyone understands that mnemonic phrases = the key to security, and random signatures = inviting trouble, but I was still scared myself recently: I clicked on a link titled "AI Agent automatically trades for you," and the page looked so real that I almost authorized the signature. My bottom line now is simple: never enter mnemonic phrases into any webpage or customer service chat; before signing, pause for three seconds to see whether it's an approve or a transfer of assets; for unknown contracts, better to miss the opportunity than to authorize—if you really want to try, use a small wallet and a separate browser. Anyone can boast about their storytelling, but when it comes to security, you can only rely on yourself to pay attention to the details.
