A report from 1inch highlights a significant issue in decentralized finance (DeFi), revealing that between 83% and 95% of liquidity in major pools like Uniswap and Curve is sitting idle. This translates to around $12 billion not generating any returns. The inefficiency particularly burdens retail liquidity providers, with half of them losing money due to impermanent loss. Overall, net deficits for these providers exceed $60 million, showcasing a troubling trend in capital utilization. In Uniswap v2, for instance, only 0.5% of liquidity is actively used, leaving nearly $1.8 billion ineffective. The fragmentation across more than seven million pools complicates trade routing and further diminishes potential returns. 1inch cofounder Segej Kunz describes this scenario as a "DeFi liquidity crisis," emphasizing the need for a new approach to optimize liquidity. To address these issues, 1inch has proposed the Aqua protocol. This system allows various DeFi applications to share a common capital base while ensuring users maintain custody of their assets. By simplifying the process, developers can implement the protocol with minimal code. The aim is to empower liquidity providers to keep their assets in their wallets rather than locking them in complex contracts, potentially increasing returns and reducing fragmentation in the DeFi ecosystem.
