After Binance was hacked, South Korean regulators did more than issue a statement—they directly called on exchanges to increase the proportion of assets held in cold wallets. South Korea is already one of the world’s strictest markets when it comes to exchange asset reserves: at least 80% of customer assets must be kept in cold wallets, a requirement already enshrined in regulations. Now regulators say that still isn’t enough.

This stance is worth considering. An 80% threshold would already earn top marks in many markets, but South Korean regulators’ logic is clear: the 20% left in hot wallets is the only window of opportunity for hackers. The smaller that window, the better—ideally, so small that hackers have no chance to strike. The Binance incident has effectively given the entire industry a free penetration test.

For ordinary users, the significance of this isn’t how South Koreans manage South Korean exchanges, but that it provides a benchmark to refer to. When evaluating a platform in the future, don’t just look at whether it has proof of reserves. Ask one more question: What percentage of its assets are held in cold wallets? How are the private keys managed? Is it using multisig or a single signature? These questions may not seem very polite, but they’re more useful than blaming people after a liquidation.

Of course, cold wallets aren’t a cure-all. They address “theft on-chain,” but they can’t prevent misappropriation, fake reserves, or insider wrongdoing. To truly reduce risk, you need transparent reserves, independent audits, and regulators who actually conduct inspections. All three are essential.

The above does not constitute investment advice.
