Recently, I found a bunch of people's wallets with contract authorizations all set to "unlimited," which is basically the same as leaving your house key in the door and turning it twice without removing it... Usually, it's no big deal, but when something goes wrong, you can't even sleep peacefully. Many phishing scams or fake routers are just waiting for you to give this old authorization; one day, if the contract acts up, they can directly use the permissions to drain your balance like a buffet.

Now I’m used to: revoke permissions after use, especially for new DApps, unfamiliar cross-chain bridges, and various "slippage-saving" aggregators. Don’t complain about the trouble—paying a little gas to revoke is much cheaper than getting robbed once. Modularization and the DA layer have been hot topics among developers lately, and users are often confused—that’s normal. As more chains emerge and interactions become more fragmented, authorizations are more likely to become a chaotic mess.

My mom asked me a few days ago: "You can transfer your money just by clicking a button, isn’t that too crazy?" I could only reply half-heartedly: It’s not the chain that’s crazy, it’s you giving too much permission and forgetting to revoke it... Anyway, revoking a few authorizations before bed is just like locking the door.
