Stream Finance
Summary
Stream Finance was an Ethereum-based DeFi yield aggregator founded in February 2024 by Diogenes Casares and Solal Afota that collapsed in November 2025 after disclosing a $93 million loss attributed to an off-chain trader who allegedly misappropriated protocol assets to cover personal margin-call losses. The collapse caused its xUSD synthetic stablecoin to depeg from $1.00 to approximately $0.26 within 24 hours, triggering an estimated $285 million in cascading exposure across multiple interconnected DeFi protocols including Morpho, Euler, Elixir, Silo, and Gearbox. A federal civil lawsuit (Case No. 3:2025cv10524, N.D. Cal.) was filed on December 8, 2025, accusing operator Caleb McMeans and trader Ryan DeMattia of misappropriation; as of mid-2026 the protocol entered a formal wind-down under a newly incorporated holding company with no confirmed creditor recovery timeline.
