What is Vitalik Buterin proposing for DeFi?

Ethereum co-founder Vitalik Buterin has proposed replacing DeFi's traditional debt-and-liquidation model with an options-based framework. The goal is to create crypto investment products and synthetic assets that can better withstand market crashes without triggering sudden liquidations.

Why does Buterin want to move away from collateralised debt positions (CDPs)?

Most DeFi protocols rely on collateralised debt positions, where users borrow against crypto collateral. If collateral values fall too quickly, positions can be liquidated automatically, often causing forced selling and amplifying market volatility.

How would an options-based DeFi system work?

Instead of using debt backed by collateral, the proposed model would use options contracts to provide exposure to assets such as the US dollar or crypto indexes. This could allow users to maintain market exposure without facing immediate liquidation when prices move sharply.

How could this reduce liquidations during crypto crashes?

Under Buterin's concept, portfolio allocations would gradually drift away from target levels rather than triggering abrupt liquidations. This smoother adjustment process could reduce the cascading liquidations that have contributed to severe DeFi market downturns in the past.

Why are price oracles a problem in DeFi?

Price oracles provide external market data to DeFi protocols, but they can become points of failure during volatile markets. Incorrect pricing, delays or manipulation can trigger unnecessary liquidations and create systemic risks across decentralised finance platforms.

How would Buterin's proposal reduce oracle risks?

The proposed system could rely on slower-moving price feeds rather than real-time oracle updates. According to Buterin, this would reduce the need for split-second decisions and lower the risk of protocols reacting to manipulated or inaccurate market data.

What does this mean for algorithmic stablecoins?

Buterin suggested that algorithmic stablecoins built on an options-based framework could be safer than those dependent on real-time oracle feeds and liquidation mechanisms. He said he would feel more comfortable holding stablecoins designed around this structure.

Is this proposal being implemented on Ethereum now?

No. The idea remains a research proposal and has not been implemented on Ethereum. Significant technical and economic questions still need to be addressed before the concept could move beyond theory.

Buterin explores options-based overhaul for DeFi

Written by Jon CuthbertPublished Jun. 2 2026Last Updated Jun. 2 2026

Ethereum co-founder Vitalik Buterin has proposed a new approach to decentralised finance that could reduce the risk of sudden liquidations by replacing debt-backed structures with options-based systems.

The proposal would allow users to gain exposure to assets such as the US dollar or cryptocurrency indexes without relying on collateralised debt positions that can be forcibly liquidated during periods of market volatility.

“What if we use options as the base of DeFi, instead of CDPs and liquidations?”

Said Buterin in a research post shared on X.

Under the current DeFi model, users often borrow against crypto collateral to create synthetic assets or stablecoins, with positions automatically liquidated if collateral values fall below required thresholds.

Buterin argued that an options-based framework could create a smoother adjustment process during market downturns, reducing the risk of cascading liquidations and forced selling events that have historically amplified volatility across decentralised finance markets.

The proposal would also reduce dependence on real-time price oracles by using slower-moving data feeds, potentially lowering the risk of manipulation and incorrect pricing during periods of market stress.

Buterin said he would feel “much safer” holding algorithmic stablecoins built on an options-based structure than systems that depend heavily on real-time oracle feeds.
