I want to launch a Telegram mini-app where users earn rewards for watching short advertising spots. The flow is simple: the user opens my bot, the mini-app loads an ad, the video plays to completion, the view is verified, and an internal balance is updated instantly. Here is what I need built and handed over: • A Telegram Bot API entry point that opens the mini-app • A responsive web-app front end that streams the advertisement and detects 100 % completion • A small back-end (any modern stack is fine) to track users, impressions, and reward balances, with an admin panel for manual adjustments • Anti-fraud logic so refreshed or skipped views do not pay out • Clear, commented source code plus deployment instructions that let me move the project to my own server Acceptance will be based on: 1. Successful end-to-end reward credit after a full ad view on both mobile and desktop Telegram. 2. Admin panel shows real-time stats that match what I see as a user. 3. Code passes a quick read-through for clarity and is installable from scratch with the supplied guide. If you have previous Telegram mini-app or ad-tech experience, let me know—that will speed things up.
