Vitalik Buterin proposes replacing DeFi liquidations with options, removing real-time oracles and forced exits. A practical guide to the new risk profile.
Ethereum co-founder Vitalik Buterin published a proposal on Ethereum Research and X that would rebuild synthetic assets in decentralized finance around options contracts. The design replaces the debt-and-liquidation model used by most algorithmic stablecoins and perpetual futures with a structure that eliminates forced liquidations and the need for real-time price oracles.
The proposal targets a structural vulnerability in current DeFi synthetics. Those systems rely on collateralized debt positions (CDPs) where a user locks ETH, borrows a synthetic dollar, and faces forced liquidation if the collateral's value drops below a threshold. That liquidation depends on a real-time price oracle firing accurately under stress. Buterin argues this dependency is the main vulnerability of the model.
Real-time oracles can only rely on a small number of automated actors watching live price feeds. They leave no room for dispute resolution, recourse, or the kind of slow-but-secure verification that prediction markets already use, Buterin wrote in the Ethereum Research post. The design's trade-off is that it removes the need for instantaneous price feeds. Oracles only need to report a value at maturity, which could be weeks or months away. That delay opens the door to verification methods that are impractical in real time, including prediction-market-style dispute resolution where a slow but secure backstop oracle settles disagreements.
This is not a theoretical concern. In April, a Polymarket trader allegedly earned $34,000 by manipulating a Paris weather sensor with a hair dryer. Buterin called for a "median-of-3 independent sources" as a mandatory settlement mechanism for prediction markets after that incident. He described single-source oracles as an unacceptable centralization risk for markets with hundreds of millions of dollars at stake. In May, he went further, calling oracle quality "the biggest issue facing" prediction markets and advocating for decentralized oracles with private voting to resist manipulation.
The options framework shifts rebalancing responsibility from an automated protocol to individual users. Each ETH is split into two tokens: P and N. These two tokens always sum to one ETH regardless of price movement, so no position can go bankrupt. A user wanting USD exposure would buy deep in-the-money P tokens with strike prices far below the current ETH price. As ETH's price moves closer to the strike, the user rotates into options with lower strikes, the Ethereum Research post explains.
With liquidation-based synthetics, normal conditions feel stable until a sudden forced exit wipes out a position. With options-based synthetics, extreme price moves create a gradual, quadratic deviation from the target exposure rather than a binary wipeout. The user retains control over when and how to adjust.
The proposal changes the risk profile for synthetic asset users in several concrete ways.
Buterin has been pushing prediction markets toward what he considers more socially useful applications. In a February post on X, he warned that platforms were "over-converging to an unhealthy product market fit" by chasing short-term crypto price bets and sports gambling for revenue. He called the trend "corposlop" and stated that the sector should pivot toward generalized hedging, where both sides of a trade benefit long-term.
That hedging vision is connected to the options framework published on June 1. If prediction markets and DeFi synthetics share the same oracle and settlement layer, users could hedge personalized baskets of real-world expenses instead of just tracking a single dollar peg.
The options framework is a proposal, not a deployed protocol. Buterin has not announced a timeline or a development team. The design faces several practical hurdles:
If a major DeFi protocol or development team adopts the options framework and begins building a testnet version, the proposal moves from theoretical to actionable. A successful audit and a small-scale mainnet launch with real capital would validate the security assumptions.
If no development team picks up the design within six months, or if a competing proposal from a different team gains more traction, the options framework may remain an academic exercise. A security incident in a related options-based protocol could also set back adoption.
For traders and DeFi users, the immediate takeaway is that the CDP model's oracle dependency is now an acknowledged design flaw with a proposed alternative. Any protocol that continues to rely on real-time oracles without dispute resolution carries a structural risk that Buterin's proposal explicitly addresses.

The options framework does not eliminate all risk in synthetic assets. It replaces one set of risks – oracle manipulation and forced liquidations – with another set: active management requirements and options pricing complexity. For users who prefer deterministic exposure without the threat of a sudden unwind, the trade-off may be worth watching.
