I'm quite afraid of trouble, but there's one trouble that can't be skipped: never set "unlimited" for contract approvals. Basically, you treat your wallet like a door lock, but then you give the key directly to strangers, and even hang a "feel free to enter" sign... Usually, nothing happens, but if something does, it's like going back to the Stone Age overnight. Last week, I saw news about cross-chain bridge hacks, and everyone was talking about "waiting for confirmation," but often confirmation can't save you: approvals are there, and malicious contracts or compromised project teams can take whatever they want.

Now I basically revoke approvals right after trading, like turning off the lights before bed, and I remind myself a third time without feeling annoyed. Especially for bridges, aggregators, and various new pools, the experience is convenient, but don’t give too much permission; if you must leave a limit, just leave enough for use. That’s it for now, maybe a bit obsessive-compulsive, but at least I sleep more peacefully.
