Recently, I’ve seen a bunch of people watching on-chain large transfers and abnormal movements in exchange hot and cold wallets, interpreting them as “smart money” moves. Honestly, what I’m more worried about are those “unlimited approval” permissions still sitting in my wallet untouched. Contract approvals are like faucets that aren’t turned off; they look fine most of the time, but when something goes wrong, it’s a flood. Revoking permissions is as important to me as sleeping: it may not make you rich immediately, but it helps you avoid pitfalls and sleep more peacefully.

What I don’t regret is: every time I finish using a DApp, I conveniently revoke any unnecessary permissions, even if it takes two extra minutes. Anyway, I’d rather pay a little more in transaction fees than wake up one day to find that assets have been transferred without any confirmation… For now, I’ll go review a few old approvals.
