Traditional wet markets in East Asia are experiencing accelerated decline, driven by the growth of e-commerce, top-down urban redevelopment, and widening intergenerational disconnection. Yet, these markets remain critical socio-cultural infrastructures, supporting local economies, ecological resilience, and intangible heritage. This chapter reimagines wet markets as urban commons, proposing that digital tools, when grounded in community narratives and co-creation, can mediate between tradition and innovation. Drawing on comparative case studies from Suzhou, Hangzhou, Singapore, Jeonju, London, and other global cities, the chapter examines how QR storytelling, mobile apps, blockchain traceability, and social media platforms can enable inclusive cultural participation and youth engagement. By integrating digital placemaking, participatory urbanism, and commons theory, this work offers a transferable framework for revitalizing wet markets as resilient, intergenerational, and culturally embedded public spaces.
