Recently, L2 has been arguing about TPS, fees, and subsidies again, it sounds quite lively, but I'm more worried that you'll be watching on the side while handing over your wallet... Here are a few "red lines" I've seen these past couple of days: Never fill in the mnemonic phrase in any scenario, whether it's airdrops, cross-chain, or accelerators—if they ask for your mnemonic, it's basically just moving your assets. Also, regarding signatures/authorizations, don't just click "Claim for free" or "Confirm" without caution; many of these are not transfers but can give you unlimited permissions, and you won't know when your account was compromised. A safer approach is: for new projects, use a small wallet first, revoke permissions after use, and if the link looks suspicious, better to miss out on subsidies than to risk rushing in blindly. Anyway, when it comes to security, losing once should be enough to make you cautious.
