Recently, I found that a few months ago I granted "Unlimited Authorization" to a certain contract again. At the time, I did it for convenience, but now it feels like I’ve left an unlocked key under the pillow... To put it plainly, revoking permissions is like going to sleep; you can endure during the day, but at night you still have to lock the door.

My current habit is: after each interaction, after finishing that cup of tea, I conveniently revoke the permission, at least reduce the limit. A couple of days ago, I saw on-chain an approval (spender=0x8a3...F21, amount=2^256-1), and my heart tightened. I’d rather click a few more times than gamble on luck.

By the way, I want to complain that recently, those on-chain data tools and tagging systems are said to be lagging or misleading. Actually, that’s normal—don’t rely too much on the "safety" tags others give you. Permissions are something you have to revoke yourself to be valid. Anyway, I’d rather be slow and confirm everything before sleeping.
