**Title: Implementing KYC (Know Your Customer) Verification through Blockchain Technology and Smart Contracts: Development of a User-Friendly Interactive Website** **Abstract** Know Your Customer (KYC) verification is a critical process for financial institutions and businesses to authenticate customer identities. However, traditional methods of KYC verification are often characterized by inefficiencies, high costs, and vulnerabilities to fraud and data breaches. This thesis explores the implementation of KYC verification utilizing blockchain technology, specifically through the Ethereum platform, alongside the deployment of smart contracts. It emphasizes the advantages of a decentralized, immutable system designed to enhance data integrity, privacy, and regulatory compliance. The objectives of this research are to establish a secure, efficient, and user-friendly KYC verification system. To achieve this, the system architecture incorporates distinct roles for Admin, Organizations, and Customers, facilitating clear functional interactions among all stakeholders. An interactive website serves as the user interface, enabling seamless engagement and interaction throughout the KYC process. The implementation leverages blockchain technology for its inherent security features, particularly through encryption and decentralized storage of customer data, which mitigate risks associated with potential data breaches. The integration of smart contracts automates and enforces the KYC verification workflows, eliminating the need for intermediaries, which leads to increased operational efficiency and a significant reduction in costs. This thesis outlines the design, development, and evaluation of the KYC verification system using blockchain technology. It highlights the key features and functionalities that contribute to a streamlined KYC verification process while ensuring compliance with regulatory standards. Ultimately, this research aims to demonstrate the effectiveness of blockchain technology and smart contracts in revolutionizing the KYC verification landscape, making it more secure, efficient, and user-centric. **Keywords:** KYC, Blockchain Technology, Smart Contracts, Data Integrity, Regulatory Compliance, Interactive Website, Ethereum.
