Vitalik Buterin Proposes Options-Based DeFi Model to Eliminate Liquidations
Ethereum co-founder Vitalik Buterin has proposed a structural shift for decentralized finance that would replace collateralized debt positions with an options-based model, potentially removing one of the most persistent risks in DeFi lending: forced liquidations.
In a post published on March 29, 2025, Buterin suggested building index-tracking assets on top of options contracts rather than relying on overcollateralized loans. Under the current DeFi model, borrowers must maintain collateral ratios above a certain threshold or risk having their positions automatically liquidated — a process that has caused billions of dollars in losses during market downturns.

How the Options-Based Model Would Work
Buterin’s proposal centers on using options as the underlying mechanism for synthetic assets and lending protocols. Instead of locking up volatile collateral that must be continuously monitored, users would purchase or sell options that cap downside risk and remove the need for liquidation engines.
The model also incorporates “slow oracles” — price feeds that update gradually rather than instantly — to prevent the rapid cascading liquidations that have plagued protocols like Compound and Aave during flash crashes. By smoothing price updates, slow oracles could give users time to respond to market movements without triggering automatic sell-offs.

“This approach reduces the systemic dependency on real-time price feeds and collateral ratio maintenance,” Buterin wrote. “It creates a more predictable risk environment for both lenders and borrowers.”
Implications for DeFi Stability
The proposal arrives at a time when DeFi protocols continue to grapple with liquidation-related losses. According to data from DeFi Llama, liquidations across major lending platforms exceeded $1.2 billion in 2024 alone. The options-based structure could fundamentally alter how risk is priced and managed in decentralized markets.
If implemented, the model would require changes to how smart contracts handle settlement and expiration dates, but Buterin argued that the trade-off is worthwhile. “The complexity is shifted from liquidation logic to options pricing, which is a more mature and well-understood financial primitive,” he said.
Industry observers noted that the proposal aligns with a broader push within the Ethereum ecosystem toward reducing reliance on overcollateralization. Projects such as Liquity and Reflexer have already experimented with alternative stability mechanisms, though none have fully eliminated liquidation risk.
Buterin did not announce any specific protocol or timeline for implementing the model, but the suggestion has already sparked discussion among DeFi developers about its technical feasibility.
