Curve Finance tweeted that many stablecoin pools (alETH/msETH/pETH) using Vyper 0.2.15 were attacked due to a faulty recursive lock. crvUSD contracts and other fund pools are not affected. As of now, the Curve Finance stablecoin pool hack has caused a cumulative loss of $73.5 million to Alchemix, JPEG'd, MetronomeDAO, deBridge, Ellipsis, and CRV/ETH pools. On August 6, Alchemix tweeted that the Curve Finance hacker had returned all of Alchemix's funds in the Curve pool. On August 19, MetronomeDAO stated that a MEV bot named "c0ffeebabe" had recovered most of the stolen funds and returned them to Metronome.
