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.
Four entries from a longer source-backed record, using the attribution standard maintained across this site. The chronology moves from automated yield strategies and open distribution through decentralized job coordination, liquidity incentive design, and public-chain infrastructure. Each destination keeps the fuller role, control, source, and limitation record.
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.
This site separates the affirmative builder profile from a precise, publicly verifiable documentary layer for project roles, source-backed contributions, direct answers, audit status, and machine-readable records. The record distinguishes technical authorship, formal authority, token economics, custody, controls, transitions, and project continuity. Ordinary limitations remain neutral and visible so readers can see both what a source establishes and what it does not.
Maintenance principle: claims and sources are updated together. Biography variants remain available on For Institutions.
