Vitalik floats building DEFI on options instead of debt

Ethereum co-founder @VitalikButerin published a research proposal on June 1 with a straightforward premise: the debt-based architecture that underpins most of DeFi today should be replaced with one built on options contracts.

The Problem With Debt-Based DeFi

Today's algorithmic stablecoins and perpetuals rely on collateralized debt positions (CDPs). Under the current model, users borrow against crypto collateral to create synthetic assets or stablecoins, and 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. These systems also depend on real-time oracle price feeds that are difficult to secure and present an attractive attack surface.

Buterin's core concern is not purely theoretical. He said he would feel "much safer" holding algorithmic stablecoins built on an options-based structure than one that depends on real-time oracle feeds that could potentially be manipulated.

How the Options-Based Model Would Work

The proposal splits one $ETH-native unit into two paired assets that always sum back to 1 ETH, so there is no collateral threshold to breach and nothing to liquidate. Buterin argued an options-based system could replace the 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.

The structure borrows from prediction markets, which have operated with slower, more deliberate oracle designs for years. A key advantage, according to Buterin, is that the design could work with "slow oracles" similar to those used by prediction markets, reducing the risk of protocols acting on incorrect price data and lessening the need for split-second automated liquidations. That slower settlement window also allows time for human recourse, something instant liquidation mechanisms cannot offer.

Buterin names the main tradeoff himself. Instead of a sharp liquidation event, a holder's exposure drifts gradually away from its target, and rebalancing that drift carries slippage costs he estimates could run to 2 percent a year or more. He acknowledged that such a system would require regular portfolio rebalancing and that it remains unclear whether those adjustments can be made cheaply and efficiently enough to avoid excessive trading costs or slippage. He reframes that drift as a feature rather than a flaw, arguing the design suits people who want price stability for future expenses, not a coin that pretends to be a dollar.

Buterin is clear about the status of the idea: it is a proposal worth exploring, not a finished blueprint. The work continues a broader push he has articulated for DeFi to move beyond incremental improvements. Rather than simply building "a better stablecoin," he has called on developers to dig deeper into core problems such as risk management and hedging future expenses, and to design solutions that traditional finance cannot replicate.
