Last night, I checked my address records and found several contracts still with "unlimited authorization," and I suddenly woke up. To put it simply, you are giving them permission to charge your card at any time, not a one-time payment. The project team may not be malicious, but things like contract upgrades, front-end hijacking, or clicking the wrong link are not something the blockchain will cut you slack on. When assets are transferred out, all you can do is post in the group, "I’m broken." So my current habit is: revoke permissions after use, just like locking the door before sleep. It’s a bit more trouble, but it’s more peace of mind.

Recently, I keep comparing RWA and US bond yields with on-chain yield products. I just want to complain about this: no matter how attractive the yield looks, you first need to make sure your wallet didn’t leave a backdoor for strangers. Anyway, I’d rather earn less than wake up one day to find my balance more "stable" than US bonds—so stable that it hits zero. That’s all for now.
