2. LITERATURE REVIEW

Numerous studies and platforms have emerged to tackle individual components of the blockchain ecosystem. Nakamoto's foundational work on Bitcoin [2] and Wood's Ethereum whitepaper [3] laid the groundwork for decentralized applications. Crosby et al. [1] emphasized blockchain'sbroaderapplicabilitybeyonddigitalcurrency.

However, a critical gap remains in consolidating this data. AlBassam [5] and Dinh et al. [9] discuss blockchain interoperability and scalability, while Singh and Verma [7] stress the importance of microservices and API integration for Web3 scalability. The need for unified access becomes evenmoreurgentinNFTmarketplaces[6],wherefragmented platformshinderuserexperience.

3. SYSTEM DESIGN AND ARCHITECTURE

Thesystemarchitectureisdividedintothreemajorlayers:

Frontend: Built using React.js with Tailwind CSS, the UI is responsive and modular. It uses React Router for smooth navigationandAxiosforasynchronousAPIcalls.Featureslike component-based architecture and state management using Context API provide a flexible UI development environment. Accessibility enhancements such as keyboard navigation, dark mode, and semantic HTML structures are integrated to improveusability.

Backend: Powered by Node.js and Express.js, the backend handles API integration, data normalization, and user authentication. It uses Mongoose to manage MongoDB interactions and includes middleware for rate limiting, CORS handling, and error logging. The backend is designed using a microservice-inspired structure where separate services handle token data, airdrops, news, and NFT details. This separationofconcernsensuresmaintainabilityandsimplifies debugging.

Database and Caching: MongoDBstorespersistentdatasuch as cached tokens, news, and user profiles. Redis is implemented for in-memory caching of frequently accessed data, reducing latency and improving user experience. Database indexing strategies and aggregation pipelines are used to optimize query efficiency, especially when sorting or filteringlargedatasets.

Security and Authentication: OAuth 2.0 protocol ensures secure access control. User sessions are handled with JWT tokens, and bcrypt hashing is applied to securely store user credentials. Backend endpoints are protected with middleware that validates access tokens and handles authorizationroles(e.g.,admin,editor,user).

Hosting and DevOps: AWS EC2 instances are used for backendhosting,whilefrontend assetsaredeployedvia AWS S3 and CloudFront for fast global access. Continuous integrationanddeployment (CI/CD)are managedvia GitHub Actions.LoggingandmonitoringareimplementedusingAWS CloudWatchandthird-partytoolslikeLogRocket.

System Scalability: The system is built with scalability in mind. Horizontal scaling is supported by containerization using Docker, and plans for Kubernetes-based orchestration are under consideration for future enterprise deployment. Load balancing and fault tolerance are addressed using AWS ElasticLoadBalancer(ELB)andmulti-zonedeployment.

API Architecture: All data is fetched through RESTful API endpoints that abstract third-party API structures and

standardize the responses. This design decouples the frontend from any external dependency changes and enables internal processing such as filtering, pagination, and enrichmentbeforesendingdatatotheclient.

4. FEATURES AND FUNCTIONALITY

The Web3 & Blockchain Aggregator Website incorporates a wide array of real-time and interactive functionalities that collectivelyestablishitasaunifiedplatformfordecentralized ecosystem insights. One of the core features is the Trending Coins module,whichdynamicallydisplayscategorizedtokens such as top gainers, top losers, new coin listings, and stablecoins. This module utilizes the CoinGecko API for data fetching, while caching is managed using MongoDB to optimizeperformanceandsupportfilteringoperations.Users can easily browse market trends and sort data based on variousparameterstomakeinformeddecisions.

Another key component is the Blockchain News Section, which aggregates and displays crypto-related news from trusted sources such as Crypto Panic and NewsAPI. This section is enhanced by interactive elements, including like and dislike buttons, and categorizes articles under headers like trending topics, token specific news, and press releases. Each item is linked to the original article to ensure transparencyandfacilitatefurtherreading.Thecachinglayer in MongoDB helps store news items for repeated access and sorting, significantly improving load times and user experience.

The platform also features a comprehensive Airdrop Tracker, listing both live and upcoming airdrop campaigns

along with detailed metadata such as project name, blockchain network, eligibility criteria, deadlines, and participation links. These entries are sourced through API integrationandstoredinthebackenddatabase,whichallows users to filter and sort airdrops based on their preferences. This empowers users to participate in promising airdrop events directly from the aggregator without having to search onexternalplatforms.

In addition to tokens and airdrops, the system includes a Web3 Project Listing Module that showcases trending, ongoing, and upcoming decentralized projects. These listings are curated using both manual inputs and third-party API data and include information about project funding status, launchphases,andrelevantlinks.The Funding Tracker submodule provides insights into recent fundraising rounds, displaying details such as project name, investment stage (e.g.,seed,SeriesA),investorname,andfundingamount.This offersavaluablereferencepointfordevelopersandinvestors tomonitoremergingprojects.

To support official announcements and protocol developments, a Press Release Feed is integrated into the platform, displaying verified updates on token launches, roadmap developments, and exchange listings. The system also implements secure user authentication using JWTbased login and session handling. Users can register, save preferences, and bookmark specific content for quick access. AlthoughcurrentlyimplementedusingNode.jsandMongoDB, plans exist for integrating OAuth and MetaMask for decentralizedidentitylogininfutureversions.

The entire frontend is developed using React.js and styled with Tailwind CSS, ensuring a responsive and accessible user experience across devices. The design supports dark mode and follows modern UI/UX standards to improve readability and interactivity. Navigation between sections is managed through React Router, and optimization techniques such as lazyloadingareappliedtoenhanceinitialloadspeeds.

A planned feature is the Admin Dashboard, which will enable administrative users to manage content submissions, moderate project listings, update news feeds, and oversee system analytics. This dashboard will be role-based, with access control mechanisms to maintain security. Overall, the platform’s modular architecture and real-time capabilities make it a powerful tool for aggregating decentralized data and facilitating user interaction in the evolving Web3 landscape.
