Super Defi

Problem Statement

Super DeFi is a revolutionary DeFi protocol enabling capital-efficient, composable European-style options. Each purchased option mints an ERC1155 token, which can then be used as collateral to create subsequent option layers, unlocking theoretically infinite liquidity efficiency. Writers earn premiums across multiple layers, while buyers gain flexible exposure to underlying assets like BTC or ETH. Unlike traditional options that lock fresh collateral per contract, our layered design multiplies capital utility, reduces inefficiencies, and enables deep, liquid markets. Fully settled at maturity via oracles, the protocol combines security, automation, and composability, empowering retail traders, protocols, and institutions to optimize yield and risk management in decentralized finance.Key Features:European Settlement: Options can only be exercised at maturity. Layered Collateralization: Option tokens are used as collateral for subsequent options. Premium Flow: Buyers pay premiums to writers at each layer. Risk Management: Contingent payout chains limit exposure per layer.
