Are you also worried about this terrifying scenario—accidentally clicking on a phishing link and losing your private key, with your life savings instantly wiped out? Such incidents happen on the blockchain every day; one slip-up and you're completely wiped out.

In traditional wallet models, once the private key is leaked, hackers won't give you any reaction time. They immediately drain all native tokens from your wallet, and the process is so fast you can't react. On the blockchain, assets are exposed without any fault tolerance.

That's why you need to add a "security door" to your funds. My approach is to store most of my idle funds in a debt position. This way, my wallet always appears empty—no tokens, just enough Gas fees to keep it alive. Even if hackers trick the private key and open the wallet, there's nothing inside.

But here's the problem: how can they transfer my assets? They would first need to execute a "repayment" operation within the protocol, then "redeem" the collateralized assets. In other words, they must first send enough stablecoins into my wallet before proceeding to the next step.

See, this is impressive. It significantly raises the attacker's cost and difficulty. More importantly, this time delay gives me a chance to counterattack. Once I detect abnormal activity, I can use other authorization methods to rescue my debt position.

Many people don't realize that using the interaction logic of DeFi protocols for asset isolation is a seriously overlooked security strategy. It not only helps you manage idle funds but can also save your life in critical moments.
