Recently, I’ve seen several people fall for phishing links again, hardware wallets are out of stock and hard to get, and security awareness has improved, but many people only focus on “don’t lose your private key,” ignoring the chronic danger of contract authorization. Especially those that immediately ask you to “approve unlimited,” I used to take the easy way out too, but later I forgot to revoke when changing accounts or projects, effectively leaving a long-term pass for strangers’ contracts.

Now I treat revoking permissions like brushing my teeth before bed: after completing an interaction, I casually check the authorization, turn off what I can, and only leave the necessary limit if I really need to. Honestly, the blockchain won’t remind you “this permission is still active,” and if the other contract has issues or gets compromised, your funds will suffer too. Don’t think it’s a hassle—fewer lucky escapes, more execution, and you can sleep more peacefully.
