⚠️ Curve Finance, a large DeFi protocol, experienced a vulnerability that resulted in losses of more than $47 million. This was caused by a bug in the reentrant locks of Vyper, a contract-oriented programming language. 📉 The CRV token decreased by 5% after the news. The founder of Curve Finance immediately reimbursed part of the losses, and a certain user returned 2,879 ETH (~$5.4 million). This case is a reminder of potential vulnerabilities in smart contracts and DeFi.
