Last night I wanted to sleep but didn't dare to, when I checked my wallet I realized I had accidentally given "unlimited approval" to a certain contract during the last testnet... Basically, it's like leaving the house key under the doormat—doesn't seem like a big deal during the day, but the more I think about it at night, the more anxious I get. Recently, cross-chain bridges have been hacked again, and there was that oracle error wave, everyone in the group is spamming "waiting for confirmation," and I also got scared: confirmation is fine, but if you don't revoke permissions, it's like leaving a hole open forever. Just now, I revoked each of my commonly used approvals one by one, tapping confirm with my finger like a gentle paw, and I felt a bit more at ease. I used to follow some people who promote "one-click approval to save trouble," but the more I watched, the more I felt they were encouraging me to be lazy, so I unfollowed them—saving my life is more important. That's all for today; I’ll sleep after revoking the permissions.
