If I could only keep one habit: every time I finish using a dApp, I make sure to revoke the contract authorization, especially those with "unlimited" permissions, which make me uneasy. Honestly, granting permissions is like locking the door before bed; you might not lock it, and nothing happens immediately, but if something does happen, it’s a one-time wipe. Recently, I’ve seen a bunch of people complaining about MEV, unfair ordering, validators taking profits while retail investors get the crumbs... Anyway, you can’t control these things, so at least tighten the control over who can move my tokens in my wallet. It’s a bit more trouble, but my OCD just wants to feel secure.
