Flying Tulip is Andre Cronje's most ambitious DeFi protocol — a single unified application where liquidity is shared across spot trading, lending markets, perpetual futures, and the ftUSD native stablecoin. No fragmented liquidity. No wasted capital.
In Flying Tulip, a single deposit is simultaneously collateral for borrowing, liquidity for spot swaps, margin for perps, and backing for ftUSD. No fragmentation.
Andre Cronje is the creator of Yearn Finance, the protocol that invented yield optimization; Fantom (now Sonic), the high-speed EVM chain; Keep3r Network, the decentralized job market; and Solidly, the ve(3,3) model that spawned dozens of forks.
Flying Tulip is his synthesis — taking everything he learned from building, breaking, iterating, and rebuilding — into a single unified DeFi primitive where every line of code serves the mechanism, not the marketing.
Andre announced Flying Tulip on his blog with characteristic understatement: "It combines spot, lending, perps, and a stablecoin. That's it." The simplicity of the description belies the depth of the engineering underneath.

Spot trade. Lend. Go long or short with up to 50× perps. Mint ftUSD. André Cronje built it — you just have to use it.
