Decentralized Warranty Management on Ethereum: A Framework for Transparency, Security, and Ownership Transfer

Abstract

This paper presents a decentralized application (dApp) for warranty management built on the Ethereum blockchain using smart contracts. The solution addresses key challenges in conventional warranty systems, such as lack of transparency, difficulty in transferring ownership, and reliance on centralized control. By leveraging Solidity-based smart contracts, the proposed framework establishes a transparent and immutable warranty registry that supports registration, verification, and ownership transfer of warranties. A React-based frontend, integrated with MetaMask, provides an intuitive interface for warranty-related operations. Comprehensive testing and deployment in real-world scenarios demonstrate the system’s ability to manage the complete warranty lifecycle while enhancing security and transparency. This work contributes to the growing body of research on blockchain-enabled supply chain and asset management by offering a practical framework for decentralized warranty systems in production environments.
