Recently, I’ve seen people once again fixating on big transfers on-chain and interpreting any movement between an exchange’s hot and cold wallets as “smart money”... I’m actually more afraid of the quiet kind: contract authorizations still have unlimited allowances left attached. In plain terms, you think the funds are in your wallet, but the keys were already handed out once; after that, if anything goes wrong, you don’t even need to confirm anything.

My habit is like checking the door before going to sleep: after using a dApp, I immediately revoke any unnecessary approve permissions, especially those with unlimited amounts. It’s not that someone is guaranteed to hack you—people forget, links get changed, contracts get upgraded. And when that “instant” moment hits in the queue, you simply don’t have time to react.

My “redundancy” approach is pretty crude too: I keep two backups like usual, but authorization isn’t something you should “backup.” If it can be deleted, delete it—fewer approvals means fewer heartbeats to worry about. For now, that’s how I do it.
