Recently, blockchain security company CertiK released a report stating that losses from cryptocurrency vulnerability exploitation in September 2023 exceeded US$300 million, making it the worst month so far this year. Among them, the Mixin Network attack on September 23 caused losses as high as US$200 million. On the other hand, DeFi lending protocol Yield Protocol announced that it will permanently close at the end of December due to global regulatory pressure and insufficient business demand. In addition, Polygon co-founder Jaynti Kanani announced her resignation from her daily job, saying that she would monitor from the sidelines to provide help for the Decentralized Autonomous Organization (DAO). In terms of price action, the DeFi market has had a mixed week, with the majority of the top 100 tokens still trading in the same price range as last week.
