I just stumbled on a bunch of “unlimited allowance” contracts in my wallet again, and it honestly gives me chills. Put simply: you open the door for it and hand it the keys. Most of the time it’s fine, but if the project team upgrades the contract, the front end gets hijacked, or you accidentally click a phishing link, your assets aren’t just “possibly at risk”—they’re “taken outright.” Revoking permissions is as important as sleeping: you can get through a day without doing it, but sooner or later, you’ll have to deal with it.

I thought I only used big-name protocols, so it should be okay—turns out, when I checked, an unlimited allowance connected to a small yield pool I used half a year ago was still just sitting there… Back then, I bundled it together with the RWA and on-chain treasury bond yield stuff and thought, “Yeah, stability feels pretty good.” Now I realize, forget whether it’s stable or not—leaving permissions open is the real instability.

Anyway, my current habit is: revoke after use. If you can keep the authorization small, don’t set it to unlimited. For anything long-term, do periodic checkups too—so you don’t end up staring at night-time “ECG-style” fluctuations all day while the risks you actually should be watching end up being the ones you miss.
