The problem Starks Marketplace 2023 solves

DIGITAL ART
Digital art was an early use case for NFTs because of the ability of blockchain technology to assure the unique signature and ownership of NFTs.
COLLECTIBLES
NFTs can represent digital collectibles like physical card collections in a wholly digital format.
TICKETING
Tickets for any type of event have been suggested as a user case for NFTs. One such use case is the possibility for artists to receive royalties on resales. Another one would be a more intimate relationship between fans and artists.
GAMES
NFTs can also be used to represent in-game assets, such as digital plots of land controlled by the user instead of the game developer. NFTs allow assets to be traded on third-party marketplaces without permission from the game developer.
Virtual Worlds
Community NFTs such as "Bored Ape Yacht Club" and "Pudgy Penguins" entitle token holders to benefits, including membership entry to a private Discord server, by validating the NFT exists in the wallet against access.
Music
Blockchain and the technology enabling the network have given the opportunity for musicians to tokenize and publish their work as non-fungible tokens. This has extended the list of options for musicians and artists alike to monetize and profit from their music as well as other content surrounding the themes of the music and the artist's public image. Additionally, NFTs have provided the opportunity for artists and touring musicians to recuperate lost income due to the 2020 COVID-19 pandemic, which resulted in music industry revenues falling nearly 85%.

Challenges we ran into

1. We faced a private key generation problem, where we could not generate the private key due to the integration of the MUMBAI FAUCET Network.
2. We faced a problem in deployment because for deploying, we need a paid marketplace, so we hosted it on the local system as mentioned in the deployment section of our GitHub repository.
