Ethereum co-founder Vitalik Buterin has proposed a fundamentally different approach to decentralized finance, suggesting that options contracts could replace collateralized debt positions as the base layer of DeFi protocols.
In a research post published Monday on ethresear.ch, Buterin outlined a way for building index-tracking assets using options rather than the debt-based structures that currently underpin most DeFi applications. The proposal directly targets one of decentralized finance’s most persistent vulnerabilities: sudden liquidations during market downturns.
“What if we use options as the base of DeFi, instead of CDPs and liquidations?” Buterin wrote in a post on X.
Under the current DeFi model, users borrow against crypto collateral to create synthetic assets or stablecoins. When collateral values fall too quickly, positions are liquidated automatically, often triggering cascading forced sales during periods of market stress. This design contributed to the severe liquidation cascades seen during major market events.
Buterin’s proposed options-based system replaces this abrupt “you get liquidated” dynamic with a smoother process. Instead of instantly losing a position when prices move against a trader, exposure would gradually diverge from a target allocation. This gradual divergence could make the system more resilient during periods of extreme volatility.
A key technical advantage of Buterin’s proposal is its compatibility with “slow oracles.” Most DeFi applications today rely on near real-time price oracle updates, which can become targets for manipulation during turbulent markets. Attackers have repeatedly exploited oracle price feeds to extract millions from lending protocols.
By contrast, Buterin said an options-based way could function with slower, less frequent oracle updates similar to those used by prediction markets. This approach would reduce the risk of protocols acting on manipulated price data and decrease the infrastructure requirements for secure DeFi operations.
The proposal is particularly relevant to algorithmic stablecoins, which have historically depended on oracle systems and collateral mechanisms that can fail under stress. Buterin said he would feel “much safer” holding algorithmic stablecoins built on an options-based structure than one dependent on real-time oracle feeds.
The concept remains theoretical and has not been implemented on Ethereum. Buterin acknowledged the system would require regular portfolio rebalancing and that it remains unclear whether those adjustments can be done cheaply and efficiently enough to avoid excessive trading costs.
The response from the DeFi community was mixed, with some developers praising the theoretical elegance while others questioned whether options-based products could achieve the capital efficiency users expect from lending protocols.
**FAQ**
**How would options-based DeFi prevent liquidations?**
Instead of borrowing against collateral that can be seized, users would purchase options contracts that gradually lose value rather than triggering immediate events during market downturns.
**Would this work with existing DeFi protocols?**
No. Buterin’s proposal would require fundamentally new protocol architectures built around options mechanics, meaning it wouldn’t be a simple upgrade to existing platforms.
**When could this launch?**
No timeline exists. Buterin’s post is a research proposal meant to spark discussion and experimentation.
