Project Description: I am looking for an expert Python developer (Telethon/Pyrogram) to build a high-end, secure Telegram Reward Bot. I have Google Cloud and Firebase ready for hosting and database. Core Requirements: Compulsory Subscription: Users must join my Telegram channel to unlock bot features. CPA Offerwall Integration: Integrate AyetStudios, AdGate Media, and OfferToro via API/Postback. Users should earn rewards for App Installs and Game Level Upgrades. Ad Networks: Integrate AdMob, AppLovin, and Unity Ads via Telegram WebView to show video/interstitial ads. Manual Task System: Ability for Admin to add custom tasks where users upload screenshots for manual approval. Referral System: Multi-level referral logic (e.g., 6 PKR per invite). Admin Panel: A robust panel to manage users, approve/reject withdrawals (EasyPaisa/JazzCash/USDT), and broadcast messages. Security: Anti-fraud system to prevent multiple accounts from the same device/IP and bot-crashing protection. Budget: $200 - $250 (Fixed) Timeline: 10-14 Days
