I just checked the approval records and found several old, long-forgotten protocols still have unlimited allowances set—scared me a bit. I quickly revoked them one by one… later I realized some of those projects haven’t been updated for two years already. That’s really worrying.

Recently, I’ve been reading community discussions about the compliance boundaries of privacy coins and mixers. The contract-approval risks are similar—trust is alive, but permissions are dead. The team you trusted may have changed hands midstream, or the protocol may have been compromised, but that wallet’s unlimited allowance has remained open, like a window that was never shut. You know the risk.

Anyway, my personal habit now is: after every interaction, I quickly check the approvals and revoke anything that should be revoked. If a project hasn’t been updated for more than half a year, I directly pull everything back.

Spend two minutes tapping through approvals before going to sleep—it’s actually more practical than researching new protocols every day.

When it comes to security, in plain terms, it’s just don’t be lazy.
