Abstract: The fusion of blockchain technologies and non-fungible tokens (NFTs) into smart city ecosystems presents new security challenges, impeding the widespread adoption of NFT in urban settings. Accordingly, this study comprehensively reviews the cybersecurity aspects surrounding NFTs within smart city environments. Firstly, a discussion of the various applications of NFTs in smart cities is provided. This is followed by an exploration of the unique cybersecurity vulnerabilities emanating from implementing NFTs in smart city ecosystems, including data privacy issues, smart contract vulnerabilities, token theft, and the potential for market manipulation, etc. Moreover, various countermeasures and best practices to negate NFTs' cybersecurity concerns and vulnerabilities have been detailed. Finally, emerging trends in NFT security are equally also analyzed. This review study provide urban planners, policymakers, technologists, students, and researchers with a refined understanding of the cybersecurity concerns of NFT in smart cities.
