Vitalik Buterin Proposes a DeFi Model Based on Options to Reduce Forced Liquidations

The co-founder of Ethereum, Vitalik Buterin, published on June 1, 2026, a research proposal aimed at transforming the design of decentralized finance (DeFi) products by replacing collateralized debt mechanisms with option contracts. This approach, published on his personal blog, proposes a model where crypto assets would follow an index (such as a basket of tokens) via options instead of overcollateralized debt positions. The main goal is to reduce the risks of forced liquidations in cases of extreme volatility, a recurring issue in DeFi protocols like Aave or MakerDAO, where users lose their collateral during sharp price drops. What Happened In his publication, Vitalik Buterin details a model where users could track a crypto index (for example, a basket including ETH, BTC, and SOL) using options instead of collateralized debt mechanisms (CDPs). Unlike CDPs, where a high collateral ratio is required to avoid liquidations, options provide dynamic risk coverage. In case of price drops, the option can be exercised to limit losses, thus avoiding forced liquidations that fuel selling spirals. Buterin emphasizes that this proposal is part of a broader reflection on the stability of DeFi protocols, as the ecosystem faces challenges related to risk management and liquidity. While no concrete implementation has been announced, Buterin described this proposal as a « step toward a more robust DeFi. » The research post was published without any link to a specific team or protocol, indicating an exploratory phase. No protocol or network has yet been mentioned for potential adoption, but projects like Synthetix or dYdX, which already use derivative mechanisms, could be natural candidates. Why This Matters This model could reduce the dependence of DeFi protocols on forced liquidations, a major issue that has contributed to cascading crashes, such as the collapse of Terra/LUNA in 2022. Widespread adoption of this model could improve the overall stability of the sector, attracting more institutional investors. Ethereum, as the dominant blockchain for DeFi, would directly benefit from this innovation, especially if protocols like Uniswap or Lido integrate option-based mechanisms. From a technical standpoint, options allow for risk coverage without relying on liquidation mechanisms, offering users greater flexibility. However, their integration into DeFi requires robust infrastructure and sufficient liquidity to be viable. Without this, users may face difficulties exercising their options, limiting the model’s usefulness. Additionally, options are complex financial products, and a poorly designed implementation could exacerbate risks rather than mitigate them. What to Watch The reactions of major DeFi protocols, such as Aave, MakerDAO, or Synthetix, which might announce experiments with this model. The development of prototypes or code on test networks (such as Goerli or Sepolia) to evaluate technical feasibility. The evolution of option liquidity in DeFi, a key factor for the adoption of this model. Potential regulatory reactions, particularly in the United States, where crypto derivative products could attract increased scrutiny. The potential impact on DeFi tokens, particularly those from projects specializing in options or derivative products, such as Synthetix or dYdX. At this stage, Buterin’s proposal remains theoretical, but it opens the door to broader reflection on the resilience of DeFi protocols. If adopted, it could mark a turning point in the design of decentralized financial products.
