Vitalik Buterin suggests an options-based DeFi model that removes liquidations and uses slow oracles to improve security and stability.
Ethereum co-founder Vitalik Buterin has outlined a new approach to decentralized finance that could reduce liquidation risks. In a post, Buterin proposed building index-tracking assets on top of options rather than collateralized debt positions (CDPs).
The concept aims to replace sudden liquidation events with a smoother adjustment mechanism during market volatility. It also removes the need for real-time oracle systems that many DeFi protocols depend on today.
According to Buterin, the model could offer a safer foundation for certain decentralized financial products.

Options-Based DeFi Could Replace Traditional Liquidations
Buterin’s proposal centers on creating index-tracking assets using synthetic options pairs derived from ETH. Instead of relying on debt-backed positions, the design would distribute value through option payoffs at maturity.
Under the model, users would not face the sharp liquidation events common in many lending and stablecoin protocols. Rather, exposure to an asset would gradually diverge from the intended target as prices move.
Buterin described this process as a smoother and more predictable adjustment mechanism. He said extreme price movements would no longer trigger a global liquidation effect across the system.
The proposal focuses on changing the way risk gets managed in DeFi. Instead of forcing immediate actions during market swings, the design allows outcomes to develop over time through the options structure.

What if the use options as the base of defi, instead of CDPs and liquidations? So instead of extreme price movements creating a sharp and global “you get liquidated” effect, instead your…

Slow Oracles Take Center Stage in New Design
A major feature of the proposal involves replacing instant oracle requirements with slow oracle systems. These are similar to the oracle mechanisms commonly used in prediction markets.
According to Buterin, the approach removes the need for real-time price feeds that must deliver immediate updates. This could reduce risks tied to oracle manipulation and inaccurate short-term pricing.
He noted that slow oracles allow more time for verification and dispute resolution. As a result, protocols may avoid situations where incorrect data causes rapid losses.
Buterin also pointed to algorithmic stablecoins as a potential use case. He stated that he would feel safer holding such assets in a system built around slow oracles rather than one dependent on instant price reporting.
The proposal reflects an ongoing effort within DeFi to improve resilience against external data risks. Oracle security remains a key concern across many decentralized applications.
Rebalancing Remains an Open Challenge
While highlighting the benefits, Buterin also identified trade-offs. He said the design would require regular portfolio rebalancing to maintain intended exposure.
That requirement introduces a new challenge for developers and researchers. Specifically, the rebalancing process must remain efficient while limiting slippage.
According to Buterin, it remains unclear whether the mechanism can become sufficiently resistant to trading costs and market inefficiencies. He described this as an open question that deserves further exploration.
Despite the uncertainty, he said the concept is worth testing and evaluating. The proposal does not introduce a finished product. Instead, it presents a framework for considering alternative ways to build decentralized financial systems.
The discussion adds to broader conversations about DeFi infrastructure and risk management. As developers continue exploring new models, options-based designs may become another area of experimentation within the Ethereum ecosystem.
