Last night, I reviewed a failed swap, slippage was a minor issue, but the most ridiculous thing was that I casually clicked on a new aggregator, and the contract authorization was given with an unlimited limit... At the time, I thought, "I'll just use it and then leave."

But when I checked the authorization list, the old dApps, testnet junk, and NFT marketplaces from half a year ago were still there, like an open faucet.
Recently, hardware wallets have been out of stock, phishing links are everywhere, so don’t take “I’m very careful” as a shield.

Honestly, unlimited authorization is like lending your wallet’s access card to strangers long-term; one day, if the contract is upgraded, the private key is stolen, or the front end is hijacked, you could be drained while you sleep.
Revoking permissions is just as important as sleeping: revoke what you don’t use, give small amounts for small transactions, don’t save gas for that one time.
You may not understand MEV, but you should understand “giving others fewer opportunities.”
Anyway, I now regularly clear permissions weekly, even if I’m lazy, I still do it.
