Abstract
Voting is a cornerstone of democratic societies, but conventional methods like ballot papers and electronic voting machines often face challenges such as lack of transparency, vote tampering, voter impersonation, delays in results, and security vulnerabilities. Addressing these concerns is critical to building trust in electoral processes.
This project explores the use of blockchain technology to create a more secure, transparent, and reliable e- voting system. Leveraging the Ethereum blockchain, smart contracts written in Solidity manage voting logic securely and prevent duplicate votes. MetaMask is integrated to handle voter authorization and wallet management, ensuring secure participation. Supplementing the blockchain, Supabase is used as a cloud database to manage ancillary data and authentication processes. The system’s front-end is built with React, providing an interactive and accessible user interface, while JavaScript handles the back-end operations that facilitate communication between the web app and blockchain smart contracts. The entire solution is implemented as a web-based application, enabling voters to participate easily from any internet- enabled device.
Through this architecture, the system combines blockchain’s core strengths: decentralization, immutability, and transparency—with modern web technologies to deliver a practical e-voting platform. The project demonstrates both the potential benefits and current limitations of applying blockchain to electoral systems, paving the way toward more trustworthy and efficient voting in the future.

Conclusion
The proposed ‘Remote Secure Voting System Using Ethereum and Smart Contract’ successfully demonstrates a robust and modern framework for secure digital voting. It effectively leverages decentralized blockchain technology to address critical flaws in traditional electoral methods such as lack of transparency, vulnerability to tampering, and limited accessibility. By strategically integrating Ethereum smart contracts, MetaMask for decentralized authentication, superbase for scalable off-chain data management, and a React-based frontend, the system ensures end-to-end verifiability, immutability, and ease of use. This makes it a viable solution for institutional, organizational, and potentially governmental elections.
