Open sourcing DeSci R&D pipelines in applied chemistry via an experimental data marketplace and tokenized reactions

About
This project implements a decentralized science (DeSci) solution where experimental chemistry data can be captured, minted as NFTs, and made publicly accessible via subgraphs on The Graph. The primary focus is on creating and managing chemistry reaction data using blockchain technology. The project consists of: • A smart contract that mints NFTs representing experimental data on the Polygon network. • A UI allowing users to input JSON-formatted data that is used to create NFTs. • Integration with The Graph, where subgraphs capture and display experimental data • Walrus, which stores experimental data streams and related images.
How it's made
We used Scaffold ETH 2 as the base implementation layer, and implemented Hard Hat, Yarn, React, Next, and Daisy UI. Contracts were written in Solidity and leveraged Open Zeppelin standard contracts for ERC-721 and ERC-20. We used The Graph, Extension, with Scaffold ETH to bootstrap a sub graph and deploy a contract to Polygon. We leveraged Walrus both for storage of large experimental data and NFT metadata images, which all linked together through the URI, which was set specifically for each experiment NFT. The hackiest thing we created was enabling our contracts to interface with one another by minting our ERC-20 token to the experimental contract, which gave us the ability to incentivize users to post experiments on-chain and be rewarded with a token ($CHEM).
