Abstract

Crowdfunding is commonly used to support different kinds of projects, but problems related to fund transparency and misuse are still observed in many platforms. Contributors often have limited control after investing, and decisions related to fund usage are mostly handled by project owners or intermediaries. To address this issue, this research proposes a blockchain-based crowdfunding system using Ethereum and smart contracts. The proposed system uses smart contracts to manage project creation, fund contribution, spending requests, and voting processes. Rules related to fund usage are written directly into the smart contract, which reduces manual intervention and improves accountability. Contributors are allowed to vote on spending requests, which helps in maintaining collective control over funds.

Ethereum was selected as the blockchain platform even though gas costs are higher, because it provides a stable network, well-tested smart contract execution, and strong tool support required for reliable implementation. A working prototype of the system was developed using Solidity, Meta-Mask, and Ethereum development tools. The prototype was tested on a limited scale with a small number of projects, contributors, and transactions to verify functionality and workflow execution rather than performance optimization. The implementation demonstrates how blockchain can improve transparency, automate fund handling, and reduce trust dependency in crowdfunding systems. The current system does not fully address scalability challenges, high gas fee fluctuations, or regulatory and legal constraints related to blockchain-based crowdfunding. Issues related to user awareness, wallet handling, and large-scale adoption are also not covered in this study and remain open for future improvement.
