Vitalik Buterin Proposes Options-Based DeFi to Replace Liquidation-Driven Debt Model

[Limited body available] The Defiant reports that Vitalik Buterin has proposed rebuilding parts of DeFi around options contracts rather than collateralized debt, with a design that splits 1 ETH into two paired assets, P and N, that always sum back to 1 ETH. In this model, the pair can be redeemed for 1 ETH at any time, and at maturity an oracle settles the payout based on an index value, eliminating forced liquidations.

The proposal matters because liquidation cascades have been one of DeFi’s most persistent failure modes, especially in stress events like March 2020, when MakerDAO’s system broke down under rapid price moves and failed keeper participation. Buterin’s idea tries to remove the auction/liquidation step entirely, which also reduces dependence on real-time oracle updates. Instead, it leans on slower, prediction-market-style oracle resolution, closer to scalar markets than to the block-by-block pricing used in most lending systems today. The article frames this as a research-level alternative to debt-backed synthetics, not a finished protocol.

The tradeoff is that the resulting asset is not a clean stablecoin: its value can drift from the target, and Buterin says it is better suited to “price stability” for known future expenses than to accounting use. He also flags rebalancing slippage as the main practical risk, estimating that users could lose around 2% per year or more if execution is poor. What to watch next: whether any protocol tries to implement the spec, whether rebalancing can be done with lower slippage, and whether the design gains traction in on-chain options and oracle infrastructure.
