Cybersecurity firm CertiK has urged digital asset exchanges to implement strict dollar limits on hot-wallet holdings rather than depending entirely on cold-storage ratios. The recommendation follows the record $6.3 billion Binance hack, which prompted various platforms to disclose cold storage figures to reassure users. CertiK suggested that hot-wallet caps should be determined by asset liability percentages, estimated withdrawal needs, and absolute loss ceilings tailored to an exchange's financial recovery resources.
In related security developments, blockchain analytics firm Elliptic reported that North Korean hackers laundered stolen funds from the Binance breach by routing approximately $430,000 through newly generated memecoins on the NEAR blockchain. Between November 5 and 7, the actors utilized liquidity pools on decentralized exchanges to obscure direct wallet transfers, a similar technique previously observed after the 2025 Bybit exploit.
Meanwhile, European financial authorities have initiated a call for industry participants to help establish unified frameworks for tokenized securities. The European Central Bank, European Commission, and European Securities and Markets Authority are accepting nominations through November 27 for the European Tokenisation Standards Group, which aims to deliver an initial set of technical standards by early 2028 to prevent market fragmentation.
