Recently, I keep seeing people with a bunch of “infinite approvals” sitting in their wallets. Plainly speaking, it’s basically like leaving a key plugged into the door at the entrance all year—nothing happens most of the time. But the moment anything goes wrong in any link—contract/front end/router—your assets can get taken straight away, and you won’t even have time to react. Revoking permissions is really as important as sleep: you can get by without doing it, but sooner or later you’ll be worn down and eventually burned out.

My own habit is: after I’ve used a protocol, I quickly turn off any approvals I don’t use often—especially cross-chain ones that have to go through a router and require waiting for confirmations. When transactions get stuck or delayed, that’s when it’s easiest for someone to get impatient and start clicking here and there. The more you click to approve, the more chaotic it gets. These days everyone is still complaining about MEV and unfair ordering—where validators take a little more and you get a little less—fine, but at least don’t leave your “front door” wide open for others to walk in… Anyway, I check my approval list every week. It’s a hassle, but it’s solid. Don’t wait until something goes wrong and then shout, “I’m really fed up!”
