This study investigates the potential of Web3 technologies for transforming digital marketing within the evolving decentralized economy. The research analyzes international experience in implementing blockchain solutions across marketing strategies of companies including SAP/Unilever, Reddit, Nike, Flipkart, and Norilsk Nickel. The hypothesis posits that isolated application of Web3 tools demonstrates limited effectiveness, whereas their integration with traditional marketing approaches ensures a qualitative leap in performance outcomes. A conducted experiment involving 9,000 users of a Telegram application confirms a 76% improvement in retention rates and a 340% increase in activity levels following the implementation of blockchain mechanics. Success is determined by three key factors: verifiable process transparency, utilitarian token value, and perceived community co-ownership. Practical recommendations for implementing Web3 solutions in marketing strategies have been developed, considering user experience simplification and regulatory compliance requirements.
