An academic study conducted by researchers from multiple Chinese universities identified 65,340 high-risk address misuse cases on Ethereum and BNB Chain, linked to approximately $574.8 million in crypto losses. The study distinguishes two types of errors: contract account misuse, responsible for losing 22,738.41 ETH and 8,681.41 BNB, and externally owned account misuse, involving 104,224.53 ETH and 9,045.29 BNB. Researchers examined over 10 million candidate addresses and 16 million exposed private keys, then analyzed approximately 2.5 million transactions with a precision rate of 99.11%. The study also reveals that attackers actively exploit these errors, particularly in 469 cases of cross-chain address reuse and 17,270 cases involving the EIP-7702 mechanism.
