Recently, everyone has been talking about modularization and the DA layer, and developers are so excited they feel like it's the New Year. Users (like me) are completely confused: no matter how many times I click, it's still that "authorization/signature" pop-up... Later, I realized that the most important thing to understand isn't the narrative, but the red line: never give your mnemonic to any site, no matter how much it looks like the official website; never slip up on signatures, especially those "free mint/airdrop claim" prompts that ask you to confirm, many of them are actually asking for unlimited authorization. Now I’ve gotten used to layering my new wallets: the main wallet only receives and never signs, a small wallet is used for testing, and I clear authorization records every few days to avoid waking up one day to find I’ve become a "passive governance participant." For now, this is enough—being cautious never hurts.
