Blockchain- Parikrama Cryptocurrency

This study examined the implementation and evaluation of an Ethereum-based ERC-20 token framework designed to support secure and decentralized digital transactions. By integrating Solidity smart contracts, MetaMask wallet authentication, Web3.py communication protocols, and a Flask-based application layer, the proposed system demonstrated an effective approach for managing digital assets within a blockchain environment. The framework successfully enabled transparent token transfers, decentralized user authentication, and secure transaction processing without dependence on centralized authorities. The research highlighted the importance of smart contract reliability, blockchain transparency, and secure wallet integration in decentralized financial applications. Analysis of existing literature and system implementation revealed that while blockchain technology offers significant advantages such as immutability, decentralization, and trustless operations, challenges related to security vulnerabilities, scalability, and transaction efficiency still require continuous attention. The adoption of proper testing, auditing, and verification mechanisms is essential for ensuring the robustness of blockchain-based systems. Overall, the findings demonstrate that ERC-20 token ecosystems provide a strong foundation for developing next-generation decentralized financial services. The proposed framework serves as a practical model for understanding blockchain integration, smart contract deployment, and Web3 application development. Future work may focus on enhancing scalability, implementing advanced security auditing techniques, optimizing transaction costs, and incorporating intelligent monitoring systems to further improve the performance and reliability of decentralized financial platforms.
