📝 Executive Summary
Cybersecurity firm CertiK is calling for crypto exchanges to implement hard dollar limits on hot-wallet holdings to improve security beyond traditional cold-storage ratios. The recommendation follows the record $6.3 billion Binance hack, which prompted exchanges like Coinbase and Gate to disclose their cold-storage percentages. CertiK warns that rigid storage requirements can inadvertently slow withdrawals and concentrate risks within key-management systems.
