Abstract

This talk presents a smart contract-based prototype for trading and settlement of derivatives on Ethereum. Users open collateralized long and short positions on-chain, while a market maker provides liquidity and hedges net exposure off-chain. The prototype is deliberately product-agnostic and supports a range of implementation choices, from direct price feeds and index construction to model-based pricing for derivatives. It also allows for configurable fee structures, exposure limits and access restrictions.
