Recently, I saw someone compare RWA, U.S. Treasury yields, and various on-chain "yield products." Frankly, where the returns come from is not the main point; what’s more easily overlooked is: those unlimited approvals in your wallet that are still active and haven't been revoked. Approvals are like giving the house key to the delivery locker attendant—usually fine, but if the attendant is replaced or the locker is broken into, your house is the first to suffer.

My current approach is: revoke permissions right after using a DApp, review historical approvals once a week, just like turning off the gas before bed—troublesome for two minutes but saves a lot of regret. Especially for new projects or contracts that frequently upgrade, don’t find it annoying. When something really goes wrong, you won’t even have time to wonder "why was it transferred." Anyway, I prefer fewer operations rather than becoming a tuition fee contributor.
