• Abstract:

  This Paper Presents The Design, Architecture, And Full-stack Implementation Of ContribuX, A Web-based Creator Support And Funding Platform That Enables Project Creators To Raise Funds From Contributors Using Secure Digital Payment Infrastructure. The System Integrates Razorpay As A Multi-instrument Payment Gateway Supporting UPI, Credit Cards, Debit Cards, Net Banking, And Digital Wallets, A Next.js 15 App Router Frontend For Server-side Rendered Campaign Pages, A MongoDB Persistence Layer Managed Through The Mongoose ODM, And NextAuth V5 For Session-based Authentication With Temporary Identity Management. The Platform Supports Campaign Creation And Management, Secure Contributor Checkout With HMAC-SHA256 Payment Verification, Transactional Email Delivery Via Nodemailer, And Real-time Toast Notifications Powered By React-Toastify. The Proposed Architecture Is Evaluated Against Established Security Frameworks For Electronic Payment Systems And Is Shown To Satisfy The Core Requirements Of Confidentiality, Integrity, Non-repudiation, Anonymity, Authentication, And Authorisation. The System Further Extends Prior Art By Supporting Multiple Payment Instruments And An Embedded Crowdfunding Model Within A Single Unified Platform. The Proposed Design Provides A Reproducible And Open-source Reference Implementation For Secure Digital Payment Integration In Modern Creator-economy Web Applications
