Lab webpage Syllabus
FNCE 559 Tokenomics
How does decentralized finance (DeFi) create value? In this hands-on course we investigate the role of “tokenomics” – the economic engines driving DeFi protocols. Beyond grasping their economic impact, we study the market, regulatory and security risks inherent to DeFi protocols. We will gain a deep understanding of the Solidity language and smart contracts on Ethereum and acquire practical experience by developing and deploying a DeFi application from scratch.
