Blockchain-Based Remittance System with Mobile Wallet Integration in Bangladesh

This research contributes a practical blockchain-based remittance framework, RemittancePay, designed specifically for the Bangladesh financial ecosystem by integrating Ethereum smart contracts with Mobile Financial Services. Unlike previous conceptual studies, this work develops and evaluates a functional prototype that supports user registration, identity verification, fund transfer, and withdrawal through secure smart contracts. The study also provides an experimental evaluation of transaction speed, API latency, throughput, and reliability, demonstrating a 100% transaction success rate and improved transparency compared to traditional remittance systems. Additionally, the proposed architecture creates a pathway for future integration with platforms such as bKash and Nagad while identifying key challenges related to scalability, regulation, and real-world deployment.
