Just now I went through a few on-chain whales’ wallets, and the more I looked, the more it felt like some things really need to be brought up—**contract approvals with unlimited allowances**. It’s not a big deal in scale, but if something goes wrong, you might end up with everything wiped out.

A lot of people who play DeFi get into the habit of just clicking “approval” and calling it done, without even paying attention to whether that limit is “unlimited.” Put plainly, you’re giving the project a key that lets them empty your wallet at any time—and not just one key. I ran into something like this before: a guy had a wallet full of assets, tapped into a small protocol to mine, and later the protocol ran into trouble. Since the approval wasn’t revoked, the next day his wallet was cleared out completely. In the end, it’s just a permissions problem—just like forgetting to lock your door before going to sleep. It’s pretty important.

Lately everyone’s been talking about the expected rate cuts. The U.S. dollar index and risk assets rise and fall together, and it gets a bit complicated. But no matter how the macro picture changes, on-chain security management is your own responsibility. Especially when the market is volatile and funds keep moving back and forth, paying attention to cleaning up approvals is more effective than any analysis.

My mom saw me up in the middle of the night checking approval records and asked, “Are your coins—like the groceries I buy—once you buy them, you just forget where you put them?” I answered offhand, “It’s more dangerous to forget who you left them with.”
