Buterin Proposes Options-Based DeFi Model to Eliminate Liquidations and Oracle Dependence
Ethereum co-founder Vitalik Buterin published a research proposal on June 1, 2026, calling for a fundamental redesign of synthetic asset creation in decentralized finance, replacing the collateralized debt model with an options-based framework that would structurally prevent liquidations.
The post, published on the Ethereum Research forum and shared on X, comes against a backdrop of escalating oracle failures and a frozen USDC contract that rattled the Ethereum developer community. In May 2025, a Chainlink oracle malfunction caused approximately $500,000 in erroneous liquidations on Euler Finance, deployed on Avalanche. On October 10, 2025, approximately $19 billion in leveraged DeFi positions were wiped out in a single day, roughly nine times the previous single-day record of approximately $2.1 billion, after oracle systems relayed stressed price data following geopolitical news.
In February 2026, an oracle manipulation attack on ZKsync left Venus Protocol with $717,000 in bad debt at that protocol alone, with additional losses possible elsewhere on the network.
The pattern is consistent enough that OWASP's 2025 Smart Contract Security Top 10 rates price oracle manipulation as the second most critical vulnerability in smart contracts.
How the Proposal Works
Buterin's framework splits one unit of ETH into two paired instruments: a "P" (positive) token and an "N" (negative) token. The two always sum to 1 ETH in value, expressed in the formula P + N = 1. At maturity, a so-called slow oracle determines how the value is divided between the two. Because no collateral ratio exists to be breached, no automated liquidator can be triggered. As Buterin wrote in the post: "P + N = 1. Hence, there is no possibility of liquidation."
Existing synthetic asset protocols, including MakerDAO DAI, Synthetix, Ethena USDe, and Curve crvUSD, have each confronted versions of the oracle and liquidation problem without fully solving it. Buterin's proposal targets this gap directly.
The slow oracle concept is borrowed from prediction market design. Rather than requiring real-time, millisecond-level price accuracy, the system tolerates 1 to 4 percent annual price drift. This design sidesteps the exact failure mode that caused MakerDAO's "Black Thursday" collapse in March 2020, when network congestion stalled oracle feeds for hours while ETH's price dropped over 20 percent in a single tick. When the feeds finally updated, mass liquidations followed. Opportunistic bots submitted 0 DAI bids for ETH collateral and won, leaving MakerDAO with over $4.5 million in unbacked debt. The protocol was subsequently forced to auction MKR tokens to recapitalize, diluting existing holders in the process.
Buterin also extended the proposal to cover custom asset baskets, meaning users could theoretically create stable-value tokens tracking a mix of goods, services, or regional purchasing power indices rather than a single fiat currency like the US dollar.
The Censorship Dimension
On X, Buterin framed the underlying motivation directly: "What if we use options as the base of DeFi, instead of CDPs and liquidations?" The proposal also responds to growing concern about dollar-pegged stablecoins controlled by US-regulated corporations. A recently surfaced incident involving a frozen confidential USDC contract, described by developer Rand as being "caught in a crossfire of another case," renewed debate about whether DeFi can deliver censorship resistance when its dollar layer is controlled by entities subject to US law. Ethereum researcher Andy Guzman stated plainly: "compliance != censorship resistance," calling for a new generation of genuinely censorship-resistant stablecoins.
Buterin said he would feel "much safer holding algorithmic stablecoins built with an options-based design than holding stablecoins that depend on real-time oracles." The proposal sits within his broader "low-risk DeFi" vision, which he has been advancing as a prerequisite for Ethereum's long-term economic sustainability, framing this not as an isolated post but as part of a sustained intellectual agenda.
Why It Matters Most Outside the US
The practical stakes are highest in regions where crypto adoption has outpaced traditional finance. According to TRM Labs, stablecoins now represent approximately 30 percent of all on-chain crypto volume, with annual on-chain stablecoin volume exceeding $4 trillion and growing 83 percent year-over-year. India ranked first on Chainalysis's 2026 Global Crypto Adoption Index, driven by a large, young, digitally literate population with growing institutional interest.
Sub-Saharan Africa posted its strongest-ever showing on the same index, with four countries in the top 20 and stablecoin volume growing over 180 percent year-over-year, concentrated in remittances, merchant payments, and savings dollarization.
In Nigeria, merchants are using USDT as a de facto settlement layer in direct response to sustained naira devaluation. Pakistan presents a similarly serious posture: the Pakistan Crypto Council was established and plans for a dedicated Virtual Assets Regulatory Authority (PVARA) were announced in March 2025, signaling meaningful institutional engagement with digital assets and placing users in cities like Karachi alongside their counterparts in Lagos as among those with the most to gain from censorship-resistant, liquidation-free infrastructure.
For these users, a sudden liquidation is not a portfolio setback. It is a loss of savings or working capital with limited alternatives available.
Equally significant is the censorship risk: a user in Lagos or Karachi holding a synthetic dollar that cannot be frozen by Circle or Tether would have materially stronger financial sovereignty than one holding USDC or USDT. Buterin's custom basket concept also carries direct emerging market relevance. A stablecoin tracking a mix of USD and locally priced goods, rather than pure USD, would better preserve purchasing power for users in import-heavy economies where dollar inflation and local inflation diverge.
Caveats and Open Questions
Buterin acknowledged two unresolved problems. The system requires regular portfolio rebalancing, and whether that rebalancing can be executed cheaply enough without excessive slippage remains an open question. This limitation is especially acute in markets with thin liquidity and high transaction fees, conditions common on local chain forks and Layer 2 deployments, which are precisely the environments most relevant to the emerging-market users described above. The proposal is theoretical research with no Ethereum implementation and no announced timeline for one.
Ethereum's DeFi ecosystem currently holds approximately $45.5 billion in total value locked, down from a 63.5 percent market share in January 2025 to roughly 53 percent today against a global DeFi TVL of around $120 billion. Whether Buterin's framework can move from a forum post to deployable infrastructure in a competitive and rapidly expanding market is the question the proposal itself cannot yet answer. For the hundreds of millions of users across South Asia and Sub-Saharan Africa for whom a liquidation means the loss of actual savings rather than a trading position, that answer carries stakes that extend well beyond market share.
