Project Summary: I am developing Kamyabi Cash, a completely free earning platform. This project requires a developer who treats security and fraud prevention as top priorities. If you struggle with advanced security systems or cannot deliver efficiently, this project will not be a good fit. 1. Security & Anti-Fraud Framework (Top Priority) Device Identification: Only one account per device is allowed. The system must rely on device fingerprinting combined with Android ID to uniquely recognize hardware, without using restricted identifiers like IMEI. Strict Enforcement: Any user detected using cloned apps, parallel environments, or multiple accounts must be banned instantly and permanently. User Verification: Integrate phone authentication via Firebase and WhatsApp, along with invisible bot protection such as reCAPTCHA or Cloudflare Turnstile, ensuring only genuine users can sign up. VPN & Proxy Blocking: Automatically detect and prevent access from VPN or proxy connections. Invite-Only Access: New accounts can only be created using a valid referral code. 2. Task Cycle & Reward Mechanics 24-Hour Task Reset: The task button should only reappear after a full 24-hour countdown from the previous completion. 3-Minute Delay Between Tasks: Each task must include a mandatory three-minute pause to promote genuine ad interaction. Task Breakdown: * Task 1 & 2 – Watch Ads: Users earn 15 PKR per task after fully viewing a Google advertisement. * Task 3 – Invite Requirement: Users must invite exactly 15 verified friends to unlock an 80 PKR reward. The claim button appears only after the 15th verified invite; if even one is missing, the reward remains zero. * Task 4 – Spin Wheel: Possible rewards: 15, 25, 50, or 199 PKR. The probability must heavily favor the lowest reward and “Try Again” outcomes. 3. Advertising Setup & Revenue Protection Main Network: Use Google AdMob as the primary ad provider. Backup Strategy: Add secondary ad SDKs such as Unity, AppLovin, or AdColony to maintain monetization if the main account is restricted. 4. Referral Structure & Income System Hierarchy: Admin should track six referral levels, while users can view up to three. Commission Rates: * Level 1: 10% * Level 2: 5% * Level 3: 2% Direct Referral Bonus: Users earn 3 PKR for each real and verified Level-1 referral. Monthly Salary Milestones: Verification-based rewards starting from 200 invites (1,500 PKR) up to 2,500 invites (30,000 PKR). 5. Technical Scope * Native Android application plus a professional landing page * Payment integrations: EasyPaisa, JazzCash, and Tether (USDT TRC-20) * Admin dashboard with full user control, blocking tools, and manual salary approval features * Community links for TikTok, Facebook, YouTube, WhatsApp groups, and Telegram
