Last night, I checked my wallet authorization records and got a little scared: a while ago, for convenience, I directly set the contract authorization to "unlimited," and I’ve forgotten which dApps I used since then... Luckily, nothing happened, but thinking about it, if I had been scammed, it might not be because of my skill level, but because the permissions were left open. Now I’ve developed the habit: revoke authorization after use, just like closing the door and turning off the gas before bed—it's a hassle for two minutes, but it gives me peace of mind all night. Recently, everyone has been complaining that miners/validators rely on MEV and that the ordering is unfair, essentially small investors are most easily used as "liquidity," so there's no need to add more risk to yourself. Take it slow, fewer thrills, more certainty.
