Summary
Curve Finance is a major decentralized exchange and automated market maker (AMM) on Ethereum, optimized for low-slippage swaps of pegged assets such as stablecoins. On July 30, 2023, several of its liquidity pools were drained of approximately $70 million due to a reentrancy vulnerability in the Vyper smart contract compiler (versions 0.2.15, 0.2.16, and 0.3.0), one of the largest DeFi exploits of 2023. Separately, founder Michael Egorov's practice of using large CRV holdings as loan collateral across multiple DeFi protocols created systemic risk that culminated in a $140 million liquidation event in June 2024, generating over $10 million in bad debt across connected protocols.
