Recently, I saw someone repeatedly clicking "Approve" on contracts/DeFi, which by default is unlimited. It feels great when you click it, but if something goes wrong later, it's like the door wasn't locked... Basically, granting permission is like giving the contract the authority to "swipe your card" from your wallet. If the contract is safe, it's fine; but if the front end gets replaced, phishing links appear, or you click the wrong thing once, it's hard to sleep peacefully.

My current habit is: revoke permissions after use, or at least reduce the limit. Revoking permissions is like sleeping—it's okay not to do it, but doing it really makes you feel secure. Recently, hardware wallets are out of stock, phishing links are rampant, and everyone's security awareness is indeed rising, but the execution always gets delayed... I do the same.

I no longer bother explaining; anyway, every time I’m too lazy to revoke, I’m just paying the price for my future self. For now, I’ll do that—go clear out a few old authorizations.
