In decentralized digital economics era, consumer engagement has transitioned from platform-based loyalty to tokenized participation and co-creation. In Web2 brand communities, gamification often produce short-term loyalty due its reliance on external, platform regulated incentives (Deterding et al., 2011). The development of Web3 technologies has integrated verified ownership, tokenized incentives and decentralized governance, providing fresh pathways for sustained consumer engagement (Tapscott & Tapscott, 2016). This study introduces the Tokenized Co-Creation (TCC) Framework, which combines Self-Determination Theory (SDT) (Ryan & Deci, 2000) and Service-Dominant logic Theory (SDL) (Vargo & Lusch, 2004) to explain how Web3 powered gamification mechanics (NFTs, Token utilities and DAOs), satisfy intrinsic motivational needs and drive brand value co-creation (Hollebeek et al., 2019). This study contributes to the emerging literature of technological possibilities and human motivation under a overarching  Tokenized Co-Creation(TCC) Framework, thus providing both theoretical advancement and managerial direction for developing a trust-based, participatory brand communities in decentralized setting.
