Why do I always get itchy and click on those "approve unlimited" options? Honestly, it's because I'm afraid of missing out: when I see that small price difference flash in the pool, I just want to complete the transaction quickly, lazy to sign again later, saving a few seconds as if I’ve made a profit... As a result, I leave permissions open for several days.

But now I really think revoking authorization is just as important as sleeping. If you don’t lock the door before sleeping, you’ll feel uneasy sooner or later. Especially recently, with cross-chain bridges having issues again, and oracles acting up, everyone is just "waiting for confirmation," and I’ve also become cautious: on-chain risks aren’t gone just because you don’t see them.

My current clumsy approach: give a specific limit whenever possible, revoke after use, rather than signing multiple times and leaving a backdoor. Anyway, small and secure, don’t open a big hole in the fish tank just to save trouble. That’s how I’ll do it for now.
