According to PANews, Curve Finance stated on Twitter that many stablecoin pools using Vyper version 0.2.15 (such as alETH/msETH/pETH) were attacked due to a recursive lock failure. The team is currently assessing the situation and promises to keep the community informed of the latest developments. It is worth noting that the crvUSD contract and other fund pools have not been affected. Previously, the Ethereum programming language Vyper issued an announcement stating that the recursive locks of Vyper versions 0.2.15, 0.2.16 and 0.3.0 were invalid and stated that an investigation was underway.
