Vitalik Buterin Wants to Eliminate DeFi Liquidations With New Options-Based Model

Ethereum co-founder Vitalik Buterin has proposed a new decentralized finance (DeFi) architecture designed to replace collateralized debt systems with options-based structures, potentially eliminating forced liquidations and reducing reliance on real-time price oracles.

The proposal, published Monday on the Ethereum Research forum under the title “Building index-tracking assets on top of options instead of debt,” outlines an alternative framework for creating synthetic assets without depending on the liquidation mechanics that currently underpin most DeFi lending protocols.

A Different Approach to Synthetic Assets

At the core of the proposal is a structure built around two assets, referred to as P and N, created from one unit of Ether and linked to a strike price and maturity date.

According to Buterin, the system would allow users to mint paired assets that can later be redeemed based on the value of a reference index at expiration. Instead of requiring continuous collateral monitoring and liquidation thresholds, the mechanism settles only at maturity, using a slower oracle to determine the final outcome.

Under the model, asset P receives a payout tied to the minimum value between the strike ratio and the index price, while asset N absorbs the remaining value. Since the combined payout always equals one Ether, Buterin argues the system avoids the cascading liquidation risks commonly seen in collateralized lending markets.

The idea also references earlier concepts discussed by Vladimir Novakovski, founder of Lighter, as well as developers associated with Curve Finance.

Moving Away From Liquidation-Driven DeFi

Forced liquidations have long represented one of DeFi’s most significant structural vulnerabilities.

During the market collapse of March 2020, often referred to as “Black Thursday,” the price of Ether plunged sharply within hours, overwhelming MakerDAO’s liquidation infrastructure. At the time, failures in auction participation allowed one trading bot to acquire millions of dollars worth of Ether for effectively zero DAI, resulting in major losses for the protocol and triggering legal disputes from affected vault users.

Since then, most DeFi lending systems have been designed around increasingly sophisticated liquidation mechanisms, requiring active liquidators, high-frequency price feeds, and continuously updated oracle infrastructure.

Buterin’s proposal takes the opposite direction by attempting to eliminate liquidation auctions entirely.

Rethinking the Role of Oracles

A central theme of the proposal is reducing dependence on ultra-fast oracle systems that continuously track market prices block by block.

According to Buterin, the current liquidation-heavy structure of DeFi exists largely because protocols rely on real-time collateral monitoring. By shifting settlement to predefined expiration dates, the complexity moves away from constant price updates toward a single final settlement event.

This would potentially allow slower, more resilient oracle systems to function effectively, similar to those already used in prediction markets and other delayed-settlement mechanisms.

Rather than responding to every short-term market fluctuation, the oracle would only need to determine the final state of the index at contract maturity.

Existing Derivatives Experiments Inform the Concept

While the framework introduces a new architectural direction, several existing DeFi projects have already explored adjacent ideas in derivatives and options markets.

Protocols such as Panoptic have experimented with perpetual options systems built on Uniswap v3 liquidity positions, while Opyn’s Squeeth product introduced leveraged exposure tied to squared Ether performance. Other platforms, including Premia, have developed options-focused automated market makers with portfolio margin systems.

However, Buterin’s proposal operates at a broader structural level. Rather than building standalone derivatives products, the model seeks to create synthetic index-tracking assets through aggregated options structures instead of collateralized borrowing.

Rebalancing and Operational Trade-Offs

The proposed mechanism would require periodic rebalancing as market prices shift relative to strike levels.

According to Buterin, this process could either be managed through decentralized autonomous organizations (DAOs) operating smart contracts or handled locally through client-side software designed to reduce exposure to maximal extractable value (MEV) risks.

The system is not designed to function as a traditional stablecoin. Instead, the value of asset P would fluctuate over time based on market conditions and the distance between current prices and strike thresholds.

Buterin estimates that tracking deviation could range between roughly 1% and 4% annually. Additional risks may also emerge from slippage and rebalancing costs, which could exceed 2% per year depending on market conditions and liquidity depth.

Flexible Market Design Could Reduce Volatility Pressure

One of the more notable aspects of the proposal is its attempt to redesign how users interact with liquidity and timing within DeFi markets.

Because participants would not necessarily need to trade at precise moments during volatile conditions, the structure could allow for more flexible market coordination and potentially reduce slippage compared to conventional automated market maker systems.

In theory, this could create markets that are less dependent on constant reactive trading while still maintaining efficient price discovery and settlement.

A Broader Shift in DeFi Architecture

More broadly, Buterin’s proposal reflects a growing shift in DeFi thinking away from systems built entirely around instant liquidation and toward architectures centered on delayed settlement, programmable options, and controlled risk distribution.

The concept does not simply address a technical oracle issue. It also reexamines how liquidity, leverage, and systemic risk should function within blockchain-based financial systems.

Whether such models can operate efficiently at scale remains uncertain, particularly in markets where participants demand continuous liquidity and instant responsiveness to volatility.

Still, the proposal highlights how the next generation of decentralized finance may increasingly focus less on maximizing leverage and more on designing resilient financial infrastructure capable of functioning under extreme market stress without triggering destabilizing liquidation spirals.
