Today in Beijing, the rain was as unpredictable as gas fees on the blockchain—fluctuating wildly, causing traffic jams that even cooled my coffee... When I got home and checked my wallet records, I found it was even colder: I had previously casually given a contract "unlimited approval," just for convenience at the time. Now I think about it, it's like not locking the door when sleeping.

To put it simply, revoking permissions is on the same level as charging your phone or turning off the gas before sleeping: not doing it might not cause immediate problems, but doing it once can blow your mind. I now revoke permissions immediately after use, or just give small amounts—better to click a few more times than to dig a hole for myself.

Recently, the community has been arguing fiercely over privacy coins/mixing compliance boundaries. I don’t take sides; the more they argue, the more I feel: controlling "who can move my money" in my wallet is more practical than discussing grand principles. With a small position, permissions should be even smaller—just start with that.
