I just saw a post comparing battle rwa yield with on-chain product interest rates. Honestly, I can’t be bothered to do the math—but every time someone compares them, I end up thinking of another thing: infinite contract approvals are basically like not locking your door when you sleep.

I used to be lazy about revoking too. Later, I checked my own approval records once and found a bunch of infinite approvals from projects that were still hanging there from two years ago. My blood pressure shot up on the spot. The point is, we never know which contracts might go off the rails one day. What if a project team runs away and hackers end up rugging you for the funds? Now I’ve developed a habit: after every interaction, if I’m not planning to operate frequently afterward, I just revoke the permissions along the way—it becomes second nature.

Anyway, even if those on-chain yield products look tempting, you still have to wear your security underwear first. Oh, and you don’t necessarily have to revoke one by one manually—there are tools that can batch check approvals. Just click revoke and you’re done. Convenient. That’s it for now.
