Recently, I was reviewing wallet authorization records and realized I used to do that "approve first, ask later" thing... Unlimited approvals seemed convenient at the time, but later it was like handing the house keys to a stranger and forgetting to take them back. Honestly, revoking permissions is just as important as sleeping: you can sleep without locking the door, but if something really happens, it’s not something you can fix in one night.

Especially now, when new L1/L2 chains are offering incentives and pulling TVL, everyone rushes in to mine and then leaves. Complaining about "mining and selling" is normal, but what I worry about more is: people leave, but the approvals stay. If the contract upgrades or changes logic later, or if the front end gets compromised, your balance could be easily taken away. Anyway, now I make it a point to check my approvals after each interaction, and I revoke any unlimited approvals I see—better to do it once more next time. For now, that’s how I keep my peace of mind.
