Regulator Sandboxes for DeFi: A Comparative Analysis of Policy Effectiveness in the EU, US, and Asia Pacific

Regulatory sandboxes—controlled environments where firms test innovations under regulatory supervision—have been adopted globally to manage fintech and crypto experimentation. This paper compares sandbox approaches and policy effectiveness for decentralized finance (DeFi) across the European Union, the United States, and the Asia-Pacific. Using a mixed-methods design (document analysis, stakeholder reports, and an illustrative quantitative model), we assess objectives, design choices, risk controls, and outcomes (market access, investor protection, and innovation diffusion). Findings show the EU’s pan-European coordination aims to harmonize testing and legal clarity; the US displays fragmented, agency-led pilot initiatives with stronger enforcement posture; Asia-Pacific exhibits rapid, varied adoption with jurisdictional leaders (Singapore, Hong Kong, Australia) using sandboxes as precursors to more formal rulebooks. Policy effectiveness depends on clarity of legal scope, cross-agency coordination, and well-designed exit and scaling rules. We conclude with policy recommendations and a research agenda for empirically measuring sandbox effectiveness for DeFi.
