Ethereum co-founder Vitalik Buterin has proposed a new decentralized finance model that replaces traditional debt-based systems with an options-driven structure, aiming to eliminate forced liquidations and reduce reliance on real-time price oracles.
A shift away from liquidations
The framework centers on replacing collateralized debt positions (cdps) with options contracts, allowing traders to hold positions until expiry without automatic sell-offs triggered by price drops. Instead of being liquidated during volatility, users would choose whether to exercise or abandon positions at the end of a contract period.
Buterin argues this design could prevent the cascade of forced liquidations that have historically intensified market downturns, including major selloffs seen in March 2020 and May 2021. By removing hard liquidation thresholds, the system seeks to stabilize portfolios and reduce sudden market shocks.
Reducing dependence on price oracles
A key feature of the proposal is shifting away from high-frequency price feeds toward slower, more manipulation-resistant oracles. This would limit exposure to flash loan attacks and pricing exploits, which have repeatedly targeted defi protocols.
Oracle-related vulnerabilities have already proven costly. In April 2026 alone, attacks exploiting pricing mechanisms contributed to more than $600 million in losses across the sector, including a $285 million exploit involving Drift Protocol.
By requiring price data only at specific settlement intervals, the model narrows the window for manipulation and removes the need for constant updates that can be gamed during periods of low liquidity.
How the options structure works
Under the proposed system, assets such as Ethereum can be divided into complementary option components. One portion tracks stable or index-like returns, while the other absorbs directional price risk. Together, they maintain exposure to the underlying asset without relying on liquidation mechanisms to enforce solvency.
This structure removes the need for liquidation bots and reduces miner extractable value (mev), where automated traders exploit rapid price movements for profit. Without these bots competing in real time, network congestion and gas fee spikes could ease significantly.
Pressure on current defi models
Traditional platforms like MakerDAO, Aave, and Compound rely on cdps backed by real-time oracles. When collateral values fall below set thresholds, positions are automatically liquidated to repay debt. While effective for maintaining solvency, this approach has often amplified sell pressure during downturns and contributed to liquidity stress.
Recent on-chain data highlights the ongoing risk. As of early June 2026, more than 343,000 eth, worth roughly $547 million, was sitting near liquidation levels. A modest price decline could trigger over $166 million in forced sales from just two large positions on Maker and Aave v3.
A response to shrinking defi activity
The proposal comes as the defi sector faces declining participation and capital. Total value locked has dropped to around $78 billion, its lowest level since October 2024, following a series of security breaches and sustained outflows from major lending protocols.
At the same time, newer ecosystems such as Hyperliquid are gaining traction by offering faster and cheaper trading environments. This has increased pressure on Ethereum-based platforms to innovate beyond speed and focus on stronger financial design.
Trade-offs and next steps
While the model could reduce systemic risks and improve stability, it also shifts more responsibility onto users. Without automatic liquidations, traders would need to actively manage and rebalance their positions, potentially increasing complexity and costs.
The framework remains conceptual, but it signals a broader shift in how defi may evolve. Rather than prioritizing leverage and yield, the next phase of development could focus on minimizing forced actions and giving users clearer control over risk.
Buterin’s proposal ultimately frames decentralized finance as a system that must go beyond replicating traditional banking, aiming instead to build resilience directly into its underlying code.
