The incorporation of Internet of Things (IoT) devices with Blockchain technology confers an extensive method for magnifying the reliability, clarity, and coherence of IoT systems. This paper dispenses a distributed framework for IoT device management that makes use of smart contracts on a Blockchain testnets. Here the proposed system exploits Blockchain's built-in aspects to intercept fundamental challenges in IoT management, for instance stable device validation. By employing smart contracts, this framework makes certain the self-operated and sealed performance of management tasks. A precursor on the Ethereum Virtual Machine (EVM) based Blockchain has been developed, and the outcomes exhibit that the proposed Blockchain-based method substantially augments the certainty and reliability of IoT device management. Furthermore, the dispersed nature of the solution eliminates single point of failure and diminishing reliance on consolidated entities, by that means boosting the inclusive durability and constant of IoT ecosystems. These discoveries highlight the transmuting latent of unifying Blockchain with IoT, flagging the way for additional research and upheaval in this interdisciplinary dominion.
