Recently, I saw someone authorize a contract and just click "Unlimited" for convenience—I get it. But this is almost the same as leaving the door key in the lock without removing it... Just because nothing happens now doesn't mean you won't get exploited in the middle of the night. Anyway, after I finish interacting, I usually go and revoke the permissions, just like confirming your alarm before bed—it's a hassle, but it gives peace of mind.

Especially these days, Layer 2s are arguing about TPS, fees, and subsidies every day. Everyone is cross-chain swapping, changing addresses, claiming airdrops. The number of authorizations only increases, and residual permissions pile up even more. To put it simply, when problems do occur, it's not usually "the chain is unsafe," but more often because you've granted permissions that are too broad or too long-lasting.

I'm willing to take one extra step for security: every week, pick a quiet time to review approvals for your frequently used addresses. If you see any that are rarely used, revoke them. Better to click a few more times and pay a few extra cents in gas than to leave permissions that could keep you awake at night. That's all for now.
