One system for collateral, execution, and risk.

Founder, Flying Tulip

Flying Tulip is a unified onchain financial system designed to bring spot trading, lending, perpetual futures, insurance, and ftUSD into one protocol architecture. The goal is institutional-grade market structure: transparent collateral, onchain settlement, unified risk, and aligned incentives.

Flying Tulip launched on 23 February 2026 and continues to roll out products in guarded stages. Released or actively rolled out components include the onchain PUT position system, ftUSD, Margin Lending, and initial delta-neutral strategies. Continuing development includes Spot execution through an adaptive AMM and central limit order book, derivatives, and broader cross-margin integration.

Flying Tulip Inc is the Flying Tulip ecosystem’s software development arm for institutional credit, collateral, execution, settlement, and risk systems.

Release qualifications and supporting references are maintained in the Flying Tulip public record.

Market-structure thesis

DeFi's next step is unified market structure: collateral, credit, settlement, risk, execution, insurance, and incentives designed as one system.

Flying Tulip extends that arc from isolated primitives to a single protocol environment where collateral, execution, credit, risk, insurance, and settlement are designed together. For institutional readers, the objective is financial infrastructure they can inspect, integrate, and verify.
