NFT Marketplace
Online Stores & E-commerce
The NFT marketplace I've been developing is inspired by the concept of digital ownership and making NFTs accessible to a broader audience. Similar to how Tobiratory aims to bring real fan goods into the digital space, my platform focuses on enhancing user experience by providing a seamless interface for NFT collection, display, and interaction.
The goal of this marketplace is to democratize NFTs beyond art and investment, making them appealing and usable for various communities, particularly those emotionally connected to digital goods, such as idol activities, influencers, and entertainment enthusiasts.
… I recognize that many potential users are hesitant to engage with NFTs due to the technical barrier and unfamiliarity with blockchain technology. To address this, my platform emphasizes ease of use and accessibility, allowing even those with minimal knowledge of NFTs to enjoy their favorite creators' content through digital ownership.
Technically, the marketplace leverages Move on the Sui blockchain, chosen for its scalability, security, and suitability for user-friendly applications. This choice was inspired by how platforms like Flow and Cadence prioritize user experience and democratization of NFTs.
Our target audience includes creators and influencers who are passionate about connecting with their fans in new, innovative ways. By providing a platform that allows them to monetize their digital goods easily and effectively, we aim to create a win-win situation for creators and fans alike.
The long-term vision is to make NFTs mainstream by creating a robust, intuitive marketplace that feels natural to use, even for those who have never interacted with blockchain technology before.

I do not recommend working with him. At first, he described everything beautifully and seemed to start working, then asked to increase the cost, to which I agreed, then asked for more time, then started explaining how much a programmer's work actually costs in his country, and in the end, he completely disappeared and does not respond, he really stole a lot of my time and now I have to start over. Beware!
