DeFi insurance protocols emerged with high hopes during the 2020 crypto bull run, aiming to protect users from smart contract failures, hacks, and exploits. Projects like Nexus Mutual, InsurAce, and Cover Protocol attracted significant investment and user interest. However, as the DeFi ecosystem matured, hacks became more sophisticated and frequent, while the insurance sector struggled to keep up. Issues such as slow claims processing, high premiums, limited coverage, and reliance on capital pools vulnerable to the same exploits undermined user trust. Moreover, the speculative nature of DeFi encouraged yield farming over protection, reducing demand for insurance. Several protocols suffered from governance attacks and liquidity issues, leading to insolvency or shutdown. By late 2023, most DeFi insurance platforms had collapsed or become marginal, highlighting the difficulty of insuring against systemic risks in a rapidly evolving and often opaque environment. This article examines the factors behind the sector's decline and the lessons for future innovation.
