        abstract = {Decentralized crowdfunding application is used for raising funds in small quantities from large number of people. These funds are for a project that can be of any social cause or an innovative and creative idea. In this paper, we have used Ethereum Blockchain for building this project. We have deployed the smart contract on the Sepolia Testnet. We built the frontend using React.js library where we at first gave the functionality to connect to the Metamask wallet to identify every user uniquely as well as to facilitate the transactions of cryptocurrency. The smart contracts were deployed on the Sepolia Testnet using the Remix IDE. Here we implemented the new feature of governance where once the campaign goal is reached, then the funds will remain on hold and will not be directly transferred to the campaign owner. The voting will be broadcast to all the doners after a certain period where the doners will vote if they find that campaign is legitimate or not based on their own research during the time. Also, we trained a Support Vector classifier (SVC) model based on the dataset from the Kaggle to predict the legitimacy of the campaign based on the title and description of the campaign. The doners can use the model to predict the legitimacy of the campaign. The application will allow the campaign owner to create the campaign on the application. The backer can donate to the campaign and due to governance, the funds remain on hold and once more than 50% backers vote to the decision to transfer the funds, then only the funds will be transfer to the campaign owner. The doners can predict the legitimacy of the campaign through our application which is based on the Support Vector Classifier (SVC) model.},
