Abstract: Crowd funding has become a popular method for non-governmental organizations (NGOs) to raise funds for various causes. However, traditional crowdfunding platforms suffer from issues such as high fees, lack of transparency, and susceptibility to fraud. This paper presents a blockchain-driven framework designed to secure NGO crowdfunding transactions, leveraging the Ethereum blockchain with the Arbitrum Sepolia Layer 2 testnet for enhanced scalability and reduced costs. The framework includes a decentralized application (DApp) with user and admin modules, enabling users to create and view campaigns, donate to approved campaigns, and track fund utilization transparently. Smart contracts automate the approval and donation processes, ensuring that only verified campaigns receive funds and that all transactions are recorded immutably on the blockchain. By eliminating middlemen and providing a trustless environment, this framework significantly reduces the risk of fraud and increases donor confidence. The implementation demonstrates the potential of blockchain technology to revolutionize the crowdfunding sector, particularly for NGOs, by offering a secure, transparent, and efficient platform for fundraising..
