I now basically treat "regularly revoking unlimited authorization for contracts" like brushing my teeth before bed. Not doing it may not cause immediate problems, but if something does happen, it’s really embarrassing. To be honest, many losses aren’t caused by market fluctuations, but by the hidden landmines of the "Approve unlimited" permissions I previously granted: the project changes its frontend, the contract gets taken over, phishing links and a series of tricks, and your assets are quietly stolen while you’re still analyzing candlestick charts.

Recently, AI agents and automated trading have been quite popular. Every day, someone says, "Let the robot handle your on-chain operations." Hearing that makes me a bit cold: the more automated it is, the easier it is to forget who you gave the keys to. Anyway, I now try to authorize only small amounts for new interactions, revoke permissions after use, and avoid unlimited approvals whenever possible... It’s slower, but at least I can sleep at night.
