Today it was raining and traffic was so bad that my coffee got cold... Suddenly I realized that my on-chain permissions might also have been "cold" and neglected for a long time. In the past, to save trouble, I directly granted unlimited access in the contract authorization, which is basically like leaving the house key on the doormat outside. Usually it's fine, but when something happens, it's a big deal. Recently, hardware wallets have been out of stock, phishing links are everywhere, and everyone's security awareness has improved, but I feel like many people still forget to revoke permissions. Anyway, my current habit is: after using, I go and revoke the permissions, just like checking the door lock before bed—if I don't do it, I feel uneasy... I often make mistakes when drawing lines, but at least I won't let "laziness" trap me in authorization.
