"DeFi Ecosystem Vulnerable to Vyper Stress Tests"

A critical vulnerability in the Vyper programming language has exposed several decentralized finance (DeFi) protocols to stress tests, resulting in the theft of millions of dollars worth of cryptocurrencies. The vulnerability, caused by a malfunctioning reentrancy lock, targeted liquidity pools on the Curve Finance protocol. Pools with wrapped Ether (wETH) are at risk of attack. The incident has affected multiple projects, including Alchemix, PEGd, Metronome, and Curve DAO, with significant outflows reported. The price of CRV has also dropped, potentially impacting Aave's protocol.
