This project aims to build a decentralized application for a Dutch Auction.

• Create a new directory named v1.0 and initialize a Hardhat project.

• Implement BasicDutchAuction.sol, a Dutch auction contract.

• Allow the seller to set parameters such as reserve price, auction duration, and decrement rate.
• Conduct the auction where bidders can submit bids.
• Determine the winning bid and transfer funds to the seller.

• Write comprehensive test cases and generate Solidity coverage reports.

• Create a new directory named v2.0 and initialize a new Hardhat project.

• Create NFTDutchAuction.sol, similar to BasicDutchAuction but for selling NFTs.

• Understand ERC721 contract and implement functionality to mint, transfer, and manage NFTs.

• Write tests to ensure the correct functioning of the NFT auction contract.

• Initialize a new Hardhat project in the v3.0 directory.

• Develop NFTDutchAuction_ERC20Bids.sol, accepting ERC20 bids instead of Ether.

• Integrate ERC20 token functionality into the auction contract.

• Thoroughly test the ERC20 bidding functionality and generate Solidity coverage reports.

• Add an upgrade proxy to make NFTDutchAuction_ERC20Bids.sol upgradeable.

• Follow the guidelines for creating upgradeable contracts using the UUPS proxy pattern.
• Use the UUPS proxy instead of a transparent proxy: https://docs.openzeppelin.com/contracts/4.x/api/proxy

• Read https://eips.ethereum.org/EIPS/eip-2612
• Read https://eips.ethereum.org/EIPS/eip-712
• Implement ERC20Permit functionality for ERC20 tokens.

• Write test cases to validate the permit functionality within the context of bidding in the auction.

• Initialize a new Hardhat project in the v6.0 directory.

• Develop a ReactJS user interface for BasicDutchAuction.sol.

• Read: https://www.web3.university/article/how-to-build-a-react-dapp-with-hardhat-and-metamask
• You may use this starter repo: https://github.com/ChainShot/hardhat-ethers-react-ts-starter
  Instructions to get the app working:
  cd hardhat-ethers-react-ts-starter
  yarn install
  yarn hardhat compile
  cd frontend
  yarn install
  yarn start

• Enable users to deploy auctions, view auction information, and submit bids.

• Ensure the functionality of each section and test interactions with Metamask.

• Deploy the v6.0 DApp on the Goerli Ethereum testnet.

• Host the UI through IPFS to enable access via an ipfs:// URL.
  For example if your CID is QmRgCTtKd91QkgoTiJQky57pCRda2drKEvTyFkUznaoKm3, the URL to access the content is ipfs://QmRgCTtKd91QkgoTiJQky57pCRda2drKEvTyFkUznaoKm3
  Steps:
  Generate build files for your UI
  Install IPFS desktop and IPFS browser plugin
  Pin your UI build files to your IPFS Desktop node
  Add the IPFS url to your README.md file in your repo
  Present your fully functioning app to the TA:
  Show that your contracts are deployed on a testnet
  Show that your UI accessible by anyone through IPFS url
  Show that users can interact with your UI through IPFS and the Metamask plugin by:
  deploying a new BasicDutchAuction
  submitting a winning bid
  Use IPNS to generate a fixed name for your UI: https://docs.ipfs.tech/concepts/ipns/#mutability-in-ipfs

• Demonstrate the fully functioning app, including contract deployment, bid submission, and IPFS accessibility.

• Utilize IPNS to generate a fixed name for the UI and enhance accessibility.

Further Versions:

• Add more versions based on these solidity patterns:
