When the market is cold, on-chain security incidents tend to occur more frequently, and this has become a pattern.

Recently, a shocking case was exposed—a popular project that had been active in a major exchange wallet and logged into spot trading was hacked on the front end. During this period, user assets interacting with the contract were directly looted.

These incidents always leave people confused: is it a technical vulnerability exploited by hackers, or did the project team manipulate things from within? To be honest, sometimes it's hard to tell. But regardless, this lesson is right in front of us.

Rather than waiting for something to go wrong and then regretting it, it's better to develop good habits now. As an on-chain user, avoiding unfamiliar links and being cautious with authorizations are not enough; you also need to do these two things:

**First, regularly review and revoke wallet authorization records.** Don't leave permissions that are no longer needed on your account—it's like leaving a backdoor open for hackers.

**Second, never give unlimited permissions to any project.** Even if you trust them, set specific limits—approve only what you need, set limits for each use, and don't find it troublesome or worry about gas fees.

I hope these tips help everyone protect their assets during this cold winter.
