Recently, I came across a bunch of "unlimited authorization" again, which is basically the same as leaving the house key at the door... At the time, I was trying to save time, so I signed and went to sleep. But the real important step is actually revoking the permissions, which is just as important as sleeping: if you don't do it, it's always hanging over you; only after doing it can you feel at ease.

Especially now that hardware wallets are out of stock, many people are temporarily using software wallets, plus phishing links are everywhere. If you authorize the wrong contract, it’s no longer just about "paying fewer transaction fees." My current habit is: after using the router/aggregator or completing small arbitrage experiments, I revoke permissions casually—better to sign once more next time than leave a trap for myself.

What about you?
