Blockchain Integration in Crowdfunding: A Smart Contract-Based Approach to Fundraising

Traditional crowdfunding platforms often face challenges like lack of trust, transparency, security, and risks of fraud. To address these limitations, there is a need for a decentralized and secure system. In this paper, we propose a blockchain-based crowdfunding framework aimed to improve trust, security, and efficiency in fundraising for businesses. The framework uses smart contract written in Solidity to automate processes of campaign creation, contribution and fund allocation. The architecture is designed in multiple layers that uses tools like MetaMask for secure user interaction, and Ganache for local testing, back-end layer for API management, and security layer with multi-signature wallets, and smart contract protection to safeguard user funds. We followed a phased approach, starting with front-end design, blockchain integration, and testing before deploying to the Ethereum MainNet. This framework has decentralized fund management and enhanced security measures to address the limitations of traditional crowdfunding systems. It provides a platform where project creator can directly interact with investors. This system has a built-in mechanism for approving funding request through a voting system. This study presents a detailed technical architecture and implementation strategy. It also explores the potential of blockchain technology in strengthening trust, increasing accountability and decentralizing financial system.
