Detailed Scope of Work: KAMYABI CASH Reward App 1. Currency & Economy (KC Coins) Name: KC Coins (Kamyabi Cash). Exchange Rate: 2000 KC Coins = 50 PKR. Minimum Withdrawal: 15,000 KC Coins. Withdrawal Tax: 2,000 KC Coins per transaction. P2P Transfer (Friend to Friend): Minimum Transfer: 1,500 KC Coins. Transfer Tax: 10% (Deducted from sender). 2. Universal Ad-Flow Logic (Mandatory) Mandatory Video Ad: Before accessing ANY task (Gaming, Ad Networks, Spin, Scratch, or Invite), the user MUST watch a video ad first. The task will only unlock after the ad is completed. 3. Ad Network Tasks (5 Networks) IronSource, Meta, AppLovin, and Unity follow the same logic: Total Tasks: 8 Tasks per network (Divided into 2 sessions: 4 tasks in the morning, 4 in the evening). Gap/Lockdown: 8-hour gap between sessions. 3-minute lockdown between individual tasks. Reward Scaling: 1st session = Full coins. 2nd session = 50% coins. Rewards Per Video Ad: IronSource: 50 KC Coins per task. Meta: 60 KC Coins per task. AppLovin: 60 KC Coins per task. Unity: 60 KC Coins per task. AdMob Exclusive Tasks (One-time Daily): Task 1 & 2: Watch Video Ads (60 KC each). Task 3 (Lucky Spin): Rewards: 30, 50, 100, 199 or "Try Again". (Algorithm: 70% probability for 30/50 coins). Task 4 (Scratch Card): Random Rewards (25, 50, 75, 100 KC). Task 5 (Invite 3 Friends): Earn 150 KC. Task 6 (Invite 10 Friends): Earn 350 KC. Strict Invite/Referral Logic: Real Verification: The system must track if the invited user has registered AND played tasks. Simple link sharing on WhatsApp/Social Media will NOT count. 24-Hour Challenge: If a user completes 8/10 invites and fails to get the last 2 within 24 hours, the count resets to zero. No partial coins will be rewarded. 4. Gaming Platform Logic (7 Platforms) BitLabs, AdGate, Adjoe, Tapjoy, Offerwall, OfferToro, Gamezop. Common Gameplay Rules: Session Limit: 3 Sessions per day per platform. Gap: 3-hour gap between sessions. Playtime: Each session requires 2 to 5 minutes of active gameplay. Tiered Rewards: 1st Session: 70 to 150 KC Coins. 2nd Session: 40 to 100 KC Coins. 3rd Session: 30 to 70 KC Coins. Anti-Grinding System: If a user exceeds the daily limit or plays for an hour continuously, the reward must drop to a minimum (e.g., max 100 coins for 1 hour of extra play) to prevent system abuse. 5. Security & Anti-Fraud (Recap) One Device = One Account: Hardware-level binding. VPN/Emulator Block: Instant ban/block for VPN, Proxy, or Emulator users. Activity Tracking: Timer must pause if the app is minimized or the user switches screens. Admob appLovin Unity meta audience Facebook ads and 5 gaming platform. Strict Security Protocol (Anti-Cheat): One Device, One Account: Strict enforcement to prevent multi-accounting. Device Fingerprinting: Use unique device IDs to track and ban fraudulent users. VPN & Proxy Detection: No user should be able to access the app or offers using a VPN. Emulator Detection: Block all users trying to run the app on PC emulators (like BlueStacks). Old Security Baseline: Do you still have the previous security configurations we discussed? The security must remain 100% solid as per our original standard. Timeline: I expect this entire overhaul (UI + Ads + Security) to be completed within 10 to 15 days maximum.

Hey, I will build your KAMYABI CASH reward app with KC Coins economy, five ad network task flows, seven gaming platform integrations, and full anti-fraud security — device fingerprinting, VPN/emulator detection, and one-device-one-account enforcement. For the session/lockdown system, I will use server-side timers so users cannot bypass cooldowns by changing device clocks. Questions: 1) Is this a new build or an overhaul of an existing app? 2) Which backend/database is currently in use, if any? Looking forward to talking through the details. Kamran

I can help with this, I will build the KAMYABI CASH reward app for Android with the full KC Coins economy (earning, withdrawal, P2P transfers with tax logic), all five ad network integrations (IronSource, Meta, AppLovin, Unity, AdMob) with session limits and reward scaling, the seven gaming platform connections with tiered rewards and anti-grinding logic, plus the spin wheel, scratch card, and referral system with real verification tracking. For the anti-fraud layer, I will implement device fingerprinting using a combination of hardware IDs and SafetyNet/Play Integrity attestation rather than relying on a single device ID alone. Single identifiers can be spoofed with root access, but cross-referencing multiple signals catches emulators, cloned devices, and VPN users far more reliably. Questions: 1) Is this a new build or an overhaul of an existing app — and if existing, what is the current tech stack? 2) Which payment method will handle PKR withdrawals (JazzCash, EasyPaisa, bank transfer)? Looking forward to talking through the details.

Hi, This app has a lot of moving parts, and the real challenge is not just building the UI but making the reward logic, ad flow, referrals, and anti-fraud rules work together without loopholes. That kind of system needs careful planning from day one, especially with coin economics, timed task locks, referral validation, and abuse prevention all tied to withdrawals. I’ve worked on reward-based platforms, custom wallets, task engines, and rule-heavy systems where accuracy, fraud control, and user flow mattered more than flashy design. My approach would be to structure the app so every action is trackable, every reward is validated server-side, and every risky behavior is blocked before it affects the economy. I also understand the importance of keeping ad performance, gameplay tracking, and security stable together. As Bill Gates said, “Automation applied to an efficient operation will magnify the efficiency.” Thanks, Clifton

Ad Network Tasks: Integrate IronSource, Meta, AppLovin, Unity, and AdMob per your session limits, reward scaling, cooldowns, and daily task logic. The lucky spin, scratch cards, and invite/reward systems will be fully scripted with strict referral verification and 24-hour challenge resets. 4. Gaming Platform Logic: Seven gaming platforms (BitLabs, AdGate, Adjoe, Tapjoy, Offerwall, OfferToro, Gamezop) with session limits, tiered rewards, anti-grinding measures, and gameplay timers to prevent abuse. 5. Security & Anti-Fraud: One device = one account with device fingerprinting. VPN, Proxy, and Emulator detection for instant blocking. Activity tracking and reward pausing on app minimize.

Hi, This is Jorge from IT GLOBAL SOLUTION LLC, based in the U.S. I’ve worked on reward-based platforms and mobile systems where stability, tracking accuracy, and clean architecture are critical—especially when multiple ad networks and rule-based logic are involved. Your system is quite detailed, and the key here is structuring it in a way that keeps all rules (ads, sessions, rewards, and restrictions) centralized and easy to manage. I’d design the backend logic to handle coin economy, task validation, and timing controls reliably, while ensuring the frontend reflects all states correctly without glitches. For ad integrations (AdMob, Unity, AppLovin, etc.) and gaming/offerwall platforms, I’d standardize the flow so each network follows consistent logic while still respecting its specific reward rules. The invite system and timed challenges would be implemented with strict validation to prevent abuse and ensure accurate tracking. On the security side, I can implement strong safeguards like device fingerprinting, session validation, and behavior tracking to reduce fraud and enforce your “one device, one account” rule without affecting real users. Clean code, structured APIs, and proper testing across all flows will be a priority so the system runs reliably at scale. Happy to review your current setup and align on the best structure before starting. Best, Jorge.

Hello, I’d be glad to help build your reward app by implementing the new UI, ad-task flow, coin economy, and security logic in a stable way. I’m a full-stack developer experienced in **mobile app development, Android, C#, backend development, API integration, database management, and payment/reward flow systems**, with a strong focus on building secure, rule-based app logic. One of the key challenges in projects like this is ensuring that **the KC Coins economy, timed task/session rules, referral validation, ad-network rewards, and anti-fraud protections all work together without loopholes, abuse, or tracking inconsistencies**. My approach is to structure the app around clear task-state logic, enforce cooldowns and reward scaling at backend level, validate invite completion against real user activity, and implement strict device, VPN, proxy, emulator, and foreground activity checks so the system remains controlled and reliable. My goal is to make the new version feel like a **secure and scalable upgrade** of the app, with clean flow, stable rewards, and solid protection against misuse. Yes, I can handle the UI, ad integrations, referral logic, and security layer together within one implementation plan. A quick question: are the current ad SDKs and old security baseline already integrated in the existing codebase, or should I rebuild those parts from scratch? Best regards, Carlos

Hello, I’ve read your cash reward platform overhaul and I’m confident I can design a robust, scalable solution that matches your KC Coins economy and strict security requirements. I bring hands-on experience building secure backend systems, Android apps in C#, and integrating payment gateways with clean API layers. My approach focuses on a modular architecture: a secure wallet and currency engine for KC Coins, universal ad-flow enforcement, multi-network ad tasks with precise reward scaling, and anti-fraud measures baked into device binding, fingerprinting, and emulator/VPN checks. I’ll translate your rule-set into reliable workflows, including the 8-hour sessions, per-task cooldowns, and 24-hour invite rules, while ensuring a smooth user experience across 7 gaming platforms and 4 ad networks. With your timeline of 10-15 days, I’ll deliver a structured MVP first to validate economy and security, then expand to the full UI, ads, and platform integrations. I’ll provide clear milestones, risk mitigation, and a focused testing plan to prevent grinding and fraud. I can start immediately and work toward a polished, production-ready release.
