With MuesliSwap, a novel approach for modelling and implementing a DEX on Cardano is proposed by revisiting the traditional order book model. The exchange protocol draws from game-theoretic concepts and distinguishes itself from alternatives through simplicity, modularity, self-regulation, and full decentralization, thus paving the way for MuesliSwap to become the first operational DEX on Cardano. For technical details, we refer to the scientific whitepaper outlining the results of MuesliSwap's rigorous research.
