Secure Donation Transactions Using Blockchain Technology A Transparent and Tamper-Proof Charity Management Platform

Abstract

Online donation platforms often suffer from problems such as fraud, lack of transparency, and misuse of funds. Donors frequently hesitate to contribute because they cannot verify how their money is used. To address these issues, this paper proposes, a blockchain-based secure donation tracking system. The system integrates Razorpay payment gateway for INR transactions, Firebase for real-time data storage, and Solana blockchain for immutable donation verification. Each donation transaction is recorded on the blockchain, generating a unique transaction hash that ensures transparency and prevents tampering. The proposed system enables donors and NGOs to track donations in real time through a web dashboard while ensuring secure payment processing and blockchain verification. Experimental evaluation shows that the system significantly improves transparency, security, and trust compared to traditional centralized donation systems.
