Working Flow !!
Listing Products: Farmers can easily list their products on our website.
Unique Digital Assets: Each product is represented as a unique digital asset called an NFT (non-fungible token), ensuring it has its own digital identity that can't be replicated or divided.
Buy and Resell: Anyone can buy these NFT products from the farmers, and once someone owns an NFT, they can resell it to others.
Case Registration: If a farmer isn't satisfied with how a particular item is being treated or represented, they can register a case for it to maintain the integrity and reputation of their products.
Transparency: The complete history of transactions and interactions with the smart contract is visible to anyone, providing full transparency into how products are bought, sold, and handled, which adds trust and accountability to the entire process.
The Graph Integration
I created subgraph for this prroject and query to make various dashboard like Marketplace , History of txn, Report a case, Purchase a itwem etc
Here's the Link of the subgraph-> https://thegraph.com/studio/subgraph/helperfarm/
The code for creating the Marketplace is in: https://github.com/Vikash-8090-Yadav/Vortex2024/blob/main/TheGraph/Frontend/src/pages/marketplace.js
The code for seeing the History of the txn can be found in: https://github.com/Vikash-8090-Yadav/Vortex2024/blob/main/TheGraph/Frontend/src/components/AnalysisReposrt.jsx
and the above component is being used here in this code https://github.com/Vikash-8090-Yadav/Vortex2024/blob/main/TheGraph/Frontend/src/pages/Analysis.jsx
The code for regestering any case for the farmers can be seen here: https://github.com/Vikash-8090-Yadav/Vortex2024/blob/main/TheGraph/Frontend/src/components/Memos.jsx
amnd the above component is used here in this code -> https://github.com/Vikash-8090-Yadav/Vortex2024/blob/main/TheGraph/Frontend/src/pages/comment.jsx#L65
Covalent INtegeration
I used covalent for Taking out the Lates txn from the contract Address, Visualizing the NFT via the TokenID (Frtching the NFT txn and the holders) BUt the sad part is am geeting the error that Web3 provider connection is not setup
The code for the same can be found in this directory -> https://github.com/Vikash-8090-Yadav/Vortex2024/blob/main/TheGraph/Frontend/src/pages/marketplace.js#L48
I used covalent to check the txn hash as well and the code for this can be found here
The code is :
