Before going to sleep, I happened to clear a few permissions, and suddenly had a bit of reflection.

I used to always think things like “infinite allowance” were far away from me—until one time I watched a guy have his wallet turned upside down by an automatic transfer because he didn’t revoke permissions. After that, I formed a habit: whenever there’s a contract that’s only temporarily being interacted with, or a protocol I don’t plan to use again, I revoke it after I’m done—an unlimited approval is like not locking the door at night. Nothing happens in the daytime; but at night, who knows who might pass by.

Lately, the whole AI Agent + automated trading wave has been pretty lively to watch, but honestly, the more on-chain interactions get automated, the more authorization security feels like a shadow—you don’t pay attention to it, it doesn’t make noise, but it’s always there. A lot of people rush into new pools, set up automatic strategies, and approve infinite allowances without even carefully checking the contract address. Later, if the team runs off or the contract gets attacked, their wallets basically get emptied.

Anyway, I’ve been doing regular cleanups. I set the allowance for protocols I occasionally use to just enough, and revoke anything I’m not using. It’s like regularly backing up important data—not because you’re annoyed by the hassle, but because you can’t afford to lose it. In essence, it’s just leaving yourself some redundancy; even if it’s slower, it’s still better than a crash.
