Last night, I checked my wallet permissions and found a bunch of "unlimited" settings, and I instantly woke up. Contract authorization, to put it simply, is like giving someone your house key; usually it's fine, but if something goes wrong, they can clean out everything while you're asleep. Revoking permissions is like locking the door before bed—takes two minutes of trouble but saves you a night of anxiety. Especially now, with the community arguing every day about privacy coins, coin mixing, and compliance boundaries, no matter how fierce the debate, one fact remains unchanged: on-chain permissions are hard rules, not subject to emotion. My habit is very simple: revoke after use, set limits when possible, and don't leave yourself a "what if."
