This thesis explores the convergence and divergence of smart contrac5ng via blockchains withtradi5onal equity-based payloads as tools for economic and legal organiza5on. It places bothin the context of market vola5lity and considers the intersec5on of technological automa5onwith historical principles in contract, corporate, and financial law. By following the doctrinal,regulatory, and compara5ve facets of these two constructs, this study aims to establish ifcurrent European and interna5onal law measures – in par5cular MiFID II38 and Markets inCrypto-Assets Regula5on (MiCAR) – are able to endow legal certainty, market integrity, andinvestor proctec5on desing the ephemeral technological/metroeconomic innova5on.The text examines how smart contracts are being conceptualized as self-execu5ng coderunning on distributed ledgers, with both immutability and transparency that challengeconven5onal understanding of consent, interpreta5on, and the remediable status quo. Equityshares, instead, are the very embodiment of corporate governance instruments represen5ngright to remainder income as well as vote and residual vo5ng rights. Once digi5zed, in tokenform, they muddy the waters between securi5es regula5on and DeFi to create a hybrid “legalfabric” in which code intermingles with legal prose –some5mes colliding headlong into it.The examina5on proceeds over five substan5ve sec5ons. The first focuses on the underlyingtechnical and theore5cal understanding of blockchain and smart contracts from theperspec5ve of the Coase theorem, stressing how they can reduce enforcement cost theoryinforma5on while raising different computa5onal and governance fric5ons. The secondsec5on provides an analysis of the legal status of equity shares and smart-contract tokens,focusing on governance, transferability and remedies. The third part considers how Europeanand transna5onal regula5on respond to these challenges through a review of liability regimesfor plaTorms and custodians, insolvency segrega5on, as well as the interac5on betweenMiCAR and MiFID II. Fourth, it tackles two specific areas of law (compe55on and intellectualproperty) in which decentralized plaTorms behave as something akin to financial markets inappearance while tokeniza5on turns non-material assets into tradable goods. The last partgrounds the discussion in real-life episodes of market disrup5on, say, e.g. the 2008 financialcrash; the COVID-19 pandemic; or even the recent FTX collapse, to show how bouts ofvola5lity push and pull our law’s adaptability with respect to both tradi5onal and digitalassets. The thesis asserts that despite the powerful op5miza5ons made possible by blockchaintechnology, it is not something to make legal principles inherently obsolete, but merelychanges how they are implemented. Smart contracts automa5ze performance, but theycannot replace the interpre5ve and remedial work of law; equity shares remain the ur-modelfor alloca5ng rights in collec5ve enterprise. In periods of intense vola5lity, where they overlaphighlights the weaknesses in both code and regula5on; a coherent legal response is neededthat maintains fairness and market confidence while preven5ng crea5vity from being choked.Accordingly, the work helps answer the more general ques5on of whether “code is law,” andinstead advocates that effec5ve regula5on should marry algorithmic efficiency with norma5vereasoning characteris5c of tradi5onal legal systems.
