"What if we use options as the base of DeFi, instead of CDPs and liquidations? Instead of extreme price movements creating a sharp and global 'you get liquidated' effect, instead your position smoothly rebalances over time." — Vitalik Buterin, Ethereum Co-Founder
Ethereum co-founder Vitalik Buterin published a research proposal on June 1, 2026, on the ETHResearch forum titled "Building index-tracking assets on top of options instead of debt." The paper argues that DeFi's foundational architecture — collateralized debt positions (CDPs) with forced liquidation triggers — is structurally flawed and should be replaced with an options-based model that absorbs market shocks rather than amplifying them.
The proposal arrives as DeFi liquidation infrastructure has processed $4.65 billion across 310,000 events on Aave alone since 2020, with the broader crypto market seeing $150 billion in forced liquidations during 2025. Buterin's model would eliminate liquidation triggers entirely by splitting deposited ETH into paired option assets that always sum back to the original deposit. The trade-off: users accept rebalancing slippage — which Buterin himself warns could exceed 2% annually — in exchange for the structural impossibility of forced liquidation cascades.
The concept remains at the research stage. No implementation timeline exists. Its practical viability depends on whether rebalancing costs can be driven low enough to compete with existing CDP economics, and whether the DeFi community — heavily invested in the current architecture — has appetite for a fundamental redesign.
DeFi's liquidation mechanism functions as a systemic risk amplifier. When collateral values fall below protocol-defined thresholds, smart contracts trigger forced sales. These sales push prices lower, triggering further liquidations in a self-reinforcing cascade. The historical record quantifies the damage.
Major liquidation events:
Across 2025, total crypto liquidations exceeded $150 billion, according to CoinGlass data, averaging $400–500 million per day.
At protocol level, Aave has processed $4.65 billion in liquidations across 310,000 events since its 2020 launch through early February 2026. The protocol's Chainlink SVR (Smart Value Recapture) system — deployed to claw back MEV from liquidation events — handled $675 million in liquidations across approximately 3,900 events in its first nine months, recapturing $16 million (split 65% Aave, 35% Chainlink). All-time SVR recapture reached $18.3 million by Q1 2026.
The data illustrates a structural tension. Liquidation mechanics generate meaningful protocol revenue — Aave earned $8.56 million from a single five-day capitulation event in January–February 2026 — while simultaneously imposing billions in losses on borrowers. The protocols that administer liquidations are economically incentivized to preserve them.
Buterin's model restructures synthetic asset creation from the ground up. The mechanism works as follows:
A user deposits 1 ETH into a contract linked to a price index (designated T, which could represent USD/ETH, CPI-adjusted value, or a crypto asset basket). The contract splits the deposit into two paired positions:
The critical design constraint: P + N always equals the deposited ETH. There is no collateral ratio to breach, no liquidation threshold to trigger, and no forced selling mechanism. Price movements redistribute value between P and N holders, but no participant is forcibly ejected from their position.
In practical terms, a user wanting USD-equivalent exposure would hold the P side of a USD/ETH index, gaining as ETH's dollar price rises relative to the index target. The counterparty holding N would gain during ETH price declines. Neither party faces liquidation; both accept that their position's value diverges gradually from the target index as prices move.
The proposal credits feedback from Vladimir Novakovski, founder of the Lighter protocol, and developers of the Curve decentralized exchange.
The second component of Buterin's proposal targets oracle infrastructure. Current DeFi lending protocols require near-real-time price feeds to determine when liquidations should trigger. These feeds represent a concentrated point of failure.
Buterin argued that real-time oracles "can only rely on a small number of automated actors watching live price feeds" and "leave no room for dispute resolution or slow verification." His options model would function with slower, prediction-market-style oracles that allow time for verification and dispute resolution.
The oracle vulnerability is not theoretical. In April 2026, a trader using the pseudonym xX25Xx physically tampered with a Météo France weather sensor at Paris Charles de Gaulle Airport using a $34 hair dryer. By artificially spiking temperature readings on April 6 and April 15, the trader triggered false settlements on Polymarket weather markets, netting approximately $34,000. The incident — which resulted in criminal charges under French law carrying penalties up to seven years imprisonment and a €300,000 fine — demonstrated what Buterin described as the fundamental oracle problem: cryptographically secure systems remain vulnerable to manipulation of the data inputs they trust.
Buterin stated he would feel "much safer" holding algorithmic stablecoins built on options structures than those dependent on "potentially manipulable real-time feeds."
In the options model, price feeds update at longer intervals — hours or days rather than seconds. This window allows human verification, dispute mechanisms, and multiple oracle sources to converge, reducing the attack surface for flash loan exploits and oracle manipulation.
Buterin's proposal carries explicit economic costs that may limit its competitiveness.
Rebalancing slippage. Options-based positions tied to indices require periodic rebalancing. Each rebalance executes a trade, incurring gas costs and market impact. Buterin acknowledged this directly: "It is very easy to lose 2% per year or more from multiple rounds of slippage, and this is the largest risk by which this whole scheme might become uncompetitive."
A 2% annual drag is substantial. Current DeFi lending yields on stablecoins range from 3–8% on protocols like Aave. If the options model's structural costs consume 2% or more, the net return advantage narrows significantly, particularly for smaller positions where gas costs represent a larger proportion of value.
Stablecoin incompatibility. The model does not support accounting stablecoins — assets designed to maintain a precise 1:1 peg with fiat currencies. Price drift inherent in the options structure creates tracking errors that make the model unsuitable for the $180+ billion stablecoin market.
Active management requirement. Unlike passive CDP positions where borrowers simply maintain collateral ratios, the options model requires users to actively rebalance their positions to maintain target index exposure. Users who fail to rebalance risk losing their intended allocation, introducing operational complexity that the current lending model does not impose.
No leverage. The model as described does not enable leveraged positions. Users gain index exposure, not borrowing capacity. This is a fundamental departure from DeFi lending's core value proposition — the ability to borrow against crypto collateral — and would eliminate a primary use case if adopted as a replacement.
The on-chain options market remains small relative to lending. DeFi options protocol TVL totals approximately $50–100 million, compared to $78 billion in total DeFi TVL as of June 2026, according to DefiLlama data. This represents less than 0.15% of the DeFi market.
Lyra (now Derive) holds over 70% market share in decentralized options with approximately $100 million in TVL and monthly trading volumes exceeding $369 million. Dopex (rebranded as Stryke) has pivoted to concentrated liquidity AMMs for options pricing. Panoptic offers perpetual options built on Uniswap V3 liquidity positions.
DeFi derivatives trading volume reached $342 billion in December 2024, representing an 872% year-over-year increase, but this figure is dominated by perpetual futures, not options. Centralized venue Deribit continues to handle multi-billion-dollar daily options volume, dwarfing all on-chain alternatives.
For Buterin's proposal to reach production, the on-chain options infrastructure would need to scale by orders of magnitude — both in liquidity depth and execution efficiency.
The proposal directly challenges the economic model of DeFi's largest lending protocols. Aave, with the largest DeFi lending market, has built its revenue model partially around liquidation fees and MEV recapture. The protocol's SVR integration with Chainlink generated $18.3 million in recaptured value through Q1 2026 — a revenue stream that would not exist in an options-based architecture.
MakerDAO (now Sky) derives stability fee revenue from CDP borrowers. Its liquidation engine, while improved since Black Thursday, remains architecturally dependent on forced collateral sales.
These protocols are unlikely to voluntarily abandon their liquidation infrastructure. The more probable path, if the options model proves viable, is that new protocols adopt the architecture while incumbents integrate hybrid approaches. The ETHResearch post signals Buterin's directional preference but lacks the implementation specificity that would compel protocol-level action.
The broader context matters. DeFi TVL has declined to $78 billion from a 2025 peak of $153 billion, according to DefiLlama. A structural redesign of lending mechanics would need to demonstrate clear advantages in capital efficiency and user retention to gain traction during a period of shrinking liquidity.
Buterin's options-based DeFi proposal addresses a real and quantified problem: forced liquidation cascades have destroyed tens of billions in user value across multiple market cycles. The architectural logic is sound — removing liquidation triggers eliminates the amplification mechanism that turns market corrections into systemic events.
The economic case is less clear. A 2%+ annual rebalancing drag competes poorly with existing lending yields, particularly for smaller positions. The model's incompatibility with stablecoins and leverage removes two of DeFi's primary use cases from scope. On-chain options infrastructure lacks the depth, liquidity, and execution efficiency the model requires.
The proposal's most immediate value may be directional rather than implementational. It signals Buterin's view that DeFi's debt-and-liquidation architecture carries structural risks that incremental improvements — better oracle feeds, faster liquidation bots, MEV recapture — cannot fully resolve. Whether the DeFi community follows that signal depends on whether new protocols can demonstrate the model's viability at scale, likely on low-cost L2 environments where gas-driven rebalancing costs are manageable.
For now, the $150 billion annual liquidation machine continues to operate. The question Buterin has posed is whether it needs to.
