  The digital innovation accompanied by explicit economic incentives have
fundamentally changed the process of innovation diffusion. As a representative
of digital innovation, NFTs provide a decentralized and secure way to
authenticate and trade digital assets, offering the potential for new revenue
streams in the digital space. However, current researches about NFTs mainly
focus on their transaction networks and community culture, leaving the
interplay among diffusion dynamics, economic dynamics, and social constraints
on Twitter. By collecting and analyzing NFTs-related tweet dataset, the
motivations of retweeters, the information mechanisms behind emojis, and the
networked-based diffusion dynamics is systematically investigated. Results
indicate that Retweeting is fueled by Freemint and trading information, with
the higher economic incentives as a major motivation and some potential
organizational tendencies. The diffusion of NFT is primarily driven by a
'Ringed-layered' information mechanism involving individual promoters and
speculators. Both the frequency and presentation of content contribute
positively to the growth of the retweet network. This study contributes to the
innovation diffusion theory with economic incentives embedded.
