This project involves using the existing platform tectechain.com to expand its all-digital functions to phygital functions to enable NFTs to represent ownership or to exchange physical products. The products may be in the form of physical artworks, consumer products, services, tickets, and so forth. One pain point is that most people are reluctant to trade with cryptocurrencies, so our platform will allow users to pay in fiat currency for phygital products, and we can airdrop the corresponding NFTs to users. After receiving the NFTs, users can exchange them for physical products.
