Ethereum’s Vitalik Buterin is rethinking how DeFi handles market crashes
In a research post published Monday, Buterin proposed creating index-tracking assets using options contracts rather than the debt-based structures that underpin much of DeFi today.

What to know:
- Ethereum co-founder Vitalik Buterin proposed replacing DeFi’s debt-and-liquidation model with an options-based system that could allow users to gain exposure to assets like the U.S. dollar or crypto indexes without facing sudden liquidations during market downturns.
- Buterin argued the design could reduce reliance on real-time price oracle, a major source of risk in DeFi, though the approach would require regular rebalancing and remains an early-stage research proposal.
“What if we use options as the base of DeFi, instead of CDPs and liquidations?” Buterin wrote in a post shared on X.
Under today’s DeFi model, users typically borrow against crypto collateral to create synthetic assets or stablecoins. If the value of that collateral falls too quickly, positions can be automatically liquidated, often triggering cascades of forced selling during periods of market stress.
Buterin argued an options-based system could replace that abrupt “you get liquidated” dynamic with a smoother process. Rather than instantly losing a position when prices move against a trader, exposure would gradually diverge from a target allocation, potentially making the system more resilient during periods of volatility.
