Inspiration

The inspiration came because as a college student or someone who loves to read, I have to spend thousands of hundreds of dollars on books and then lose half of it. We decided to create a platform that protects people's money and the environment

  • Books, notes, class materials, and courses notes are represented as NFTs
  • Easily collect accurate information that is available to the public using blockchain technology

How we built it

Book Swaps application makes use of the following software:

  • Alfajores Network enables Book Swap application to be a scalable platform with fast transactions. We deployed our app on the Alfajores Network.

  • Gnosis Network enables Book Swap application to be a scalable platform with fast transactions. We deployed our app on the Gnosis Network.

  • Matic - Polygon Network enables Book Swap application to be a scalable platform with fast transactions. We deployed our app on the Polygon Network.

  • Optimism Network enables our app to be secure and cost-effective. We deployed our app on the Optimism Network

  • Valist facilitated the process of distribution of our in a secure way.

  • Spheron made it easy and was the most convenient way to deploy our web app onto a Decentralized Cloud Storage. This allows our users to access our app anywhere in the world.

  • TableLand made our work easy with the Ethereum network. This allows us to work with a relational database to store Employment references and metadata for EVM chains like Ethereum. We will definitely keep using complex TableLand functions in the future.

  • XMTP facilitated the process of communication between employers and employees, especially for important employment documents. XMTP allows our users to request employment letters and documents in and seamless and secure way.

  • Covalent API was really helpful for users' donations and tips. This facilitated the retrieval of users’ NFTs and smart contract transactions. The Covalent API endpoints to get all NFTs balance and metadata from a wallet address such as images, contracts name, NFTs images, and balances.

  • IPFS NFTStorage for data storage on IPFS that generates a transaction hash used to create an NFT of a photo.

  • textile/eth-storage: facilitated a fast way to store metadata for NFTs such: as names, locations, description, images, wallet addresses, and more. It was perfect for our use case to save their needs on the textile storage.

  • NFTPort smooths the path of the minting and donating process and eliminates the high transaction fees. Our users will not pay anything for donating NFTs or minting.

  • Solidity for the smart contract.

  • OpenZeppelin ERC721 we use the ERC721 template for faster development of our smart contract.

  • Ganache for local blockchain development.

  • Rinkeby Network is the network where we deployed our dApp.

  • React Js, Material-ui, Web3 React Js for the frontend, Material-ui, and Web3 to connect to the blockchain.

Challenges we ran into
