Buterin Proposes Options-Based Synthetics to Replace DeFi Liquidations
Ethereum co-founder Vitalik Buterin proposed on June 1 an options-based synthetic asset design that would remove the forced liquidation trigger from DeFi lending. The research-stage idea arrived one day before a June 2 flash crash that liquidated about $394 million in leveraged positions in one hour.

The Proposal
Vitalik Buterin proposed in a June 1 Ethereum Research post building synthetic, index-tracking assets on top of options, with collateralized debt removed from the base design. In one variant, 1 ETH is split into two paired option assets that always sum back to 1 ETH, a structure intended to avoid forced closures during price drops. The post is a design argument, not a protocol launch, an Ethereum roadmap commitment, or a replacement for Aave, Maker or existing stablecoins.
How Liquidation Works Today
In most DeFi lending systems, a borrower locks collateral, borrows against it and must keep the position above a required safety level. Aave expresses that level as a health factor; below 1, a liquidator can repay debt and receive collateral plus a bonus. That protects lender solvency but makes the borrower's exit timing a function of the protocol rule rather than the borrower's choice, and it gives competing liquidators a clear, public trigger to act on.
Evidence on Liquidation Stress
The risk is not hypothetical. Bitcoin's fall below $68,000 on June 2 triggered about $394 million in one-hour liquidations, including roughly $87 million in ETH positions, according to CryptoSlate. An OECD working paper found a positive relationship between liquidation activity and post-liquidation price volatility across major decentralized exchange pools, and noted that liquidators depend on the same liquidity that is scarce during stress. CryptoSlate has also reported a 2025 Chainlink-related oracle dispute that produced more than $500,000 in Euler Finance liquidations, and a 2025 ETH decline that left nearly $320 million in Ethereum-based loans within 20% of liquidation.
The Tradeoff
The proposal replaces a hard trigger with a softer risk: exposure can drift from the target unless the position is rebalanced. That reduces sudden forced sales but shifts risk to maintenance by the user. The sources do not quantify how large that drift would be under stress, and the design has not been tested in production. The sources also differ in emphasis: The Defiant presents the proposal chiefly as a route to eliminating forced liquidations and relying on slower, prediction-market-style oracles, while CryptoSlate frames the same idea as a challenge to liquidation as DeFi's core survival mechanism and stresses the drift cost. Both agree the proposal is at research stage.
Why It Matters
For Traders
Leveraged ETH positions remain exposed to liquidation cascades like the June 2 event, so monitoring health factors near key price levels is more relevant than this research-stage proposal.
For Investors
If options-based synthetics mature, they could change how collateral risk is priced across DeFi lending, though that path is long and uncertain.
For Builders
Lending protocols should weigh how a non-liquidating design would handle drift, rebalancing and oracle dependence before assuming any liquidation-free alternative.
