According to Wu, according to DeFiLlama data, in the past week (November 19-25), Optimism DEX's weekly trading volume increased by 1,800% month-on-month to more than $12 billion, setting a record high and surpassing Ethereum. However, this increase was caused by a vulnerability attack on KyberSwap, which completed $11 billion in trading volume that week. On November 23, hackers exploited the KyberSwap Elastic smart contract vulnerability and carried out an attack through a series of complex operations, stealing approximately $54.7 million in user assets; on the 23rd alone, hackers created more than $9 billion in trading volume through the KyberSwap vulnerability attack.
