Users could connect their wallets without compromising sensitive information, fostering a sense of trust and confidence in the platform. The combined use of Wagmi and Rainbow Kit exemplifies the project's commitment to both security and user-centric design.
B. Collection Creation
Through meticulous development and the utilization of Next.js, Node.js, and MongoDB, a robust and scalable NFT marketplace was successfully created. The journey began with the implementation of the Next.js frontend and MongoDB database, setting the foundation for subsequent developmental stages. Crucial to this process were the carefully crafted metadata schemas, which provided a structured framework to efficiently encapsulate key NFT information, leading to improved data organization.
By utilizing Node.js as the underlying infrastructure, the backend operations were effortlessly managed through logically structured API routes. The integration with Mongoose further enhanced this by simplifying interactions with MongoDB, leveraging highly defined models specifically catered towards NFT collections and their metadata. This not only facilitated efficient storage of data, but also allowed for flexibility and scalability to adapt to future needs.
By introducing a dedicated API endpoint, a major accomplishment was achieved, as it now allows users to easily generate NFT collections through a user-friendly interface. This interface efficiently manages both the NFT collection document and its metadata, thanks to rigorous testing that ensured the accuracy of data. Once all measures were in place, the Next.js application and Node.js server were deployed to a hosting platform. With this meticulous and all-encompassing approach, a secure foundation has been established for an adaptive NFT marketplace, specially designed to cater to the ever-changing needs of users in the dynamic realm of non-fungible tokens. The platform's structured architecture is perfectly positioned to foster growth and foster innovation within the ever-evolving NFT ecosystem.
C. NFT Minting
Users can produce and market original digital assets on the blockchain thanks to the NFT minting feature. A unique digital asset that may be purchased, sold, and traded is published on a blockchain through the process of minting an NFT, or non-fungible token. We made use of the Ethereum blockchain to implement this functionality. In order to mint an NFT, the user must first designate the blockchain on which they want their NFT to be minted and supply an image URL. The minting procedure begins when the user clicks the "Upload" button after filling out all the input forms.
At this stage, the NFT's name, description, price, blockchain name, and picture URL are all contained in a JSON object that is produced. After that, the smart contract's mint function is triggered, producing the Metadata URI and a new token on the Ethereum network. The token's attributes, including its name, symbol, and total quantity in circulation, are also specified in the smart contract. The NFT is minted and shown on the Marketplace when the function is executed. Anyone can read the name, description, price, and image of the NFT by accessing the metadata URI that is maintained on IPFS. The blockchain's token ID guarantees that each NFT token is distinct and transferable amongst users. Furthermore, as ownership information is kept on the Ethereum blockchain, users can safely and openly transfer ownership of their NFTs by using smart contracts.
The architecture of this marketplace places a strong emphasis on security, implementing top-notch practices to protect against any possible vulnerabilities. This NFT marketplace not only offers a dynamic platform for trading digital assets, but also serves as a testament to a robust and secure ecosystem. Users are invited to join in the constantly evolving world of non-fungible tokens, with the peace of mind that their transactions are well-protected.
E. User Profile
The NFT marketplace's user profile is much more than just a static page - it's a dynamic and individualized page that truly reflects one's identity and involvement within the platform. At its heart lies a profile picture, serving as a visual representation of one's presence within the vibrant NFT community. Alongside, a detailed section allows for a deeper understanding of a user's creative vision and inspirations, as well as any other relevant information they wish to share. Moreover, seamlessly integrated social media handles help bridge the gap between an individual's digital persona and their notable presence within the NFT world.
Additionally, the profile section includes the user's wallet address, providing a transparent snapshot of their financial interactions within the platform. This element contributes to a more open and secure environment for transactions and adds a layer of transparency to the user's financial engagement within the marketplace.
The profile stands out with its one-of-a-kind display of NFTs owned by the user, complete with their individual quantities. This offers a valuable glimpse into the user's diverse collection, revealing their personal tastes and interests in the NFT world. As users navigate the platform, this interactive and comprehensive profile becomes an invaluable means of self-expression, community involvement, and discovery in the ever-evolving realm of non-fungible tokens.
III. PROJECT STATUS
The project, which is focused on creating and minting NFTs on the Ethereum blockchain, has been carried out with great success. With careful attention to detail, the team has successfully fulfilled all specified requirements within the project scope, resulting in the delivery of a fully functional web application. This platform boasts the impressive capability of allowing users to effortlessly create and mint their own NFTs. However, such a feat did not come without its fair share of challenges. Along the project journey, the team encountered various technical obstacles, with the integration of the web app and web3.js libraries being a particular hurdle. This hurdle caused a temporary setback, resulting in a slight delay of the project timeline. Nevertheless, the team's resilience and resourcefulness shone through as they sought assistance from online communities and utilized available resources to effectively overcome these obstacles.
We present here, the results generated by examining the performance as well as usability components of our project. We conducted a set of tests where we measured time required for some primary operations including minting, listing and buying of NFTs via the smart contracts over Sepolia testnet . The objective in mind was to acquire real time information on operational efficiency within the network itself.
Likewise, we carried out an extensive usability analysis involving ten users selected from members of the campus community. The purpose was mainly to evaluate user friendliness, lucidity and the look of it all in the marketplace. We also sought to assess how easy it was to traverse the purchase journey, as well as general consumer experience. We collected useful information through a structured survey and used graphs for visualization of outcomes based on the usability study. These graphic representations act as a succinct means of portraying what the respondents went through while using the po
A. Performance Evaluation
Our results are presented as three graphs in our performance test on the Sepolia testnet  where we bought, listed for sale, and minted NFTs using smart contracts. These graphs depict a distinct axis as each request and a specific axis indicates the respective amount of time taken with each request. This is specifically depicted in figure 6 on NFT minting performance.
In minting, the value of 310.96 milliseconds was the average time for buying, and the highest time registered was 378.25 seconds. The duration taken to mint an NFT in terms of listing averaged at 4238.79 milliseconds with a maximum of 4 337.44 milliseconds. Our case study on minting resulted in an average time of approximately 179.29 seconds and a maximum recorded time of 226.9 milliseconds.
The obtained results prove that the NFT marketplace prototype can be considered a satisfactory one. Nevertheless, it can be improved, especially in minting that takes time compared to creation of images.
V. LIMITATIONS AND FUTURE WORK
The reliance on external APIs, such as Coinmarketcap, introduces a level of dependency on third-party services. While this enhances the functionality of the platform, any disruptions or changes to these external services could impact the real-time pricing feature. Mitigating strategies, such as backup mechanisms or alternative APIs, can be explored to address this potential demerit.
Despite the user-friendly design, the interaction with smart contracts may pose a learning curve for some users, particularly those new to blockchain technology. Clear educational resources and user guides can alleviate this challenge, ensuring that users can confidently engage with the platform.
B. Future Work
One of the critical enhancements in future developments for the NFT dApp includes automatic NFT creation. The process of minting becomes more streamlined and convenient while preserving good quality when users are endowed with the ability to either specify parameters or apply pre-defined characteristics for the manufacture of NFTs automatically.
Furthermore, it allows other listed previously minted NFTs on the marketplace of the dApp for effective representation and management. It brings in a sense of socialization, encouraging creators and collectors alike to explore beyond their own limits within the environment. On the other hand, the incorporation of modern token standards, especially ERC-721, strengthens the NFT system. Using ERC-721 improves the functionality of the NFTs since it makes it possible to trace the ownership history as well as unique attributes of individual tokens in a seamless manner.
Another aspect is having an auction and bidding into the dApp which increases competition and makes it more fun and exciting. This enables users to start auctions of their NFTSs with reserve prices and duration of sales thus creating an active marketplace atmosphere. Combined with the scheduled Ethereum mainnet rollout, the dApp will represent a full-fledged, exciting environment for NFT manufacturing, acquisition, and discover.
In summary, the creation of our NFT Marketplace decentralized application illustrates that blockchain technology has the capability to establish dependable, transparent, and user-friendly environments for managing digital assets. With our dApp, we address some of the main issues with NFT management including secure wallet connections, minting on the blockchain, and an easy NFT marketplace. This ensures that each digital asset is authentic and individual. It also confers a special status on these assets because they have their unique identities and cannot be copied by anyone in the Ethereum network. Our usability study showed that the users found our dApp easy to use and user-friendly. Moving forward, possible areas for future R&D consist of improving the scalability of NFT platforms, developing smart contracts for automatic minting of new NFTs, implementing pinning systems in conjunction with storage on IPFS, studying alternative means of generating new NFTs, as well Essentially, this marks a great leap forward from earlier versions of decentralized applications created specifically for managing and conducting trades in digital tokens.
