with development tools like Hardhat and Truffle.

To build a DApp, you first need a smart contract that will serve as the backend logic. Let’s create a simple smart contract that allows users to store and retrieve a message on the blockchain.

Example Contract:

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.0;

contract MyDapp {
    string public ipfsHash;

    event IPFSHashChanged(string newIPFSHash);

    function setIPFSHash(string memory newIPFSHash) public {
        ipfsHash = newIPFSHash;
        emit IPFSHashChanged(newIPFSHash);
    }

    function getIPFSHash() public view returns (string memory) {
        return ipfsHash;
    }
}

Update the React component to include IPFS integration:
