Last night I saw again that my friend's wallet had a bunch of "unlimited authorization," and I was completely stunned... To put it simply, this thing is like copying your house key ten times and leaving all of them in the hallway. Usually it's fine, but if something goes wrong, it can be very embarrassing. Revoking permissions for me is like sleeping: I can live without doing it, but doing it gives me peace of mind. Especially now, as everyone links ETF capital flows, U.S. stock risk appetite, and crypto market ups and downs, emotions can easily lead to clicking links or signing things impulsively. Anyway, no matter how complex my strategy is now, I always review the authorizations first—limit the amount if possible, and cut off expired ones directly. Every eliminated risk is one less pit. The only English abbreviation I mention is DeFi (the on-chain lending and swapping system), and the more frequently used it is, the more I need to keep it tidy.
