Jkardcrypto – Smart Investment Strategies for Crypto Platform

The High-Performance Backend Engine for Modern Crypto Trading.

Engineered for Scale, Security, and a Superior Developer Experience.

Intro Paragraph:
Power the next generation of complex financial applications with our latest backend overhaul. Built on the powerful MashServer Framework, this architecture delivers unprecedented performance, iron-clad security, and a suite of developer-friendly tools that let you build faster and scale seamlessly.

Architectural Pillars

🚀 Uncompromising Performance & Scalability

• High-Performance Foundation: Built on uWebSockets.js (uWS) for superior scalability and lightning-fast response times under heavy load.

• Optimized Startup: Drastically reduced server deployment and restart times through intelligent lazy loading of routes.

• Database Efficiency: A complete Sequelize ORM rework ensures proper conventions, relationships, and a singleton instance for live syncing and peak performance.

• Universal Identifier: All system IDs use UUIDv4 for consistency, security, and future-proofing.

🛡️ Iron-Clad Security & Compliance

• Multi-Method Authentication: Flexible support for session/cookie-based auth and secure JWT management using the robust JOSE library.

• Real-Time Token Validation: An edge server provides live token checks on the frontend for maximum security.

• Redis-Powered Sessions: Blazingly fast authentication processes and token management.

• Advanced Rate Limiting: Enhanced middleware protects your APIs against abuse and DDoS attempts.

• Compliance Ready: Live reCAPTCHA v3, mandatory email verification, and 2FA controls ensure secure access and regulatory compliance.

• Crypto-Native Auth: Sign-In with Ethereum (SIWE) integration for seamless Web3 wallet authentication.

⚙️ Superior Developer Experience

• Automated API Documentation: Integrated Swagger generators create comprehensive, always-up-to-date API docs effortlessly.

• Automatic Route Generation: Dynamically creates full CRUD (GET, POST, PUT, DELETE) endpoints from your data models, accelerating development.

• Robust Validation Gate: Ensures all incoming data is sanitized and secure, with human-readable error messages via AJV.

• Advanced Logging: Category and level-based, color-coded logs in a fully filterable format for effortless debugging.

• Seamless Migrations: Dedicated modules and SQL-to-JSON parsing simplify complex database transitions.

💾 Intelligent Data Management

• Powerful Querying: Advanced filtering, pagination, and sorting across all models, including support for nested content.

• Bulk Operations: Perform large-scale updates, deletions, and restorations with high efficiency.

• Soft Delete & Recovery: A “paranoid” trash system allows for safe deletion with options to restore or permanently purge records.

• Database Management: New modules for efficient database backup and restore operations.

• Live Health Checks: Comprehensive system monitoring with detailed error reporting in the admin dashboard.

🌐 Real-Time Communication Ecosystem

• WebSocket Infrastructure: Generate authenticated WebSocket channels for real-time data streaming and message handling.

• Live Notifications: Instant push notifications to users and admin teams via WebSocket from any API endpoint.

• Live User Tracking: Admins can identify online users in real-time through a central WebSocket system.

• Live Updates: Data tables, notification panels, and settings pages update in real-time without a browser refresh.

💰 Advanced Financial Engine

• Overhauled Wallet System: On-demand address generation for deposits and withdrawals across multiple wallet types (FIAT, SPOT, ECO).

• Global Payment Gateways: Integrated support for PayPal, Stripe, and more for live deposit validation and processing.

• Seamless Fund Transfers: Logic for moving funds between different wallet types within the ecosystem.

• Smart Fee Calculator: Dynamically calculates and collects fees for all transactions.

• Binary Trading Logic: Real-time trade validation with a dedicated WebSocket endpoint.

• Market Management: Admin tools to easily import and enable new trading markets.

📊 Granular Admin & Operational Control

• Roles Manager (RBAC): Efficient role-based access control with caching for tailored user permissions.

• Admin Analysis Suite: Comprehensive tools for deep analysis and reporting across all data models.

• Log Monitor: An enhanced interface to view, filter, and sort through system logs.

• Media Monitor: Manage uploads, control image sizes, and automatically convert to WebP for optimal performance.

• KYC Control: Integrated KYC verification with template rendering in user profiles.

• Cron System: A new, efficient task automation scheduler for background jobs.

🗣️ Global Readiness & Type Safety

• Full Internationalization (i18n): An i18n wrapper auto-converts strings for translation, supporting 64 locales with different fonts.

• Shared Type System: Consistent type definitions shared between backend and frontend to eliminate errors and dramatically speed up development.

• Locale Management: User language preferences are seamlessly stored in localStorage and cookies.
