Andre Cronje on why he built Flying Tulip the way he did: "Flying Tulip is the composability of a lending market that feeds directly into an order book, into derivatives and insurance, settled by our native stablecoin, Flying Tulip USD." "It makes more sense if you go back to original DeFi: the contracts were immutable, and with no direct teams involved, there were no fee extractions. The original Yearn vaults took zero fees. It was easy to build on them because you knew the code would stay the way it was and there weren't fees." "Nowadays you've got Uniswap V2, V3, V4, Aave V3, V4. There's almost always a new version and they have to, because they've become proper companies. They need to continuously upgrade and deploy new systems, and charge fees to pay the people supporting these things. But that essentially killed composability."
