Mini-game bot with economy and withdrawals

Task

The project needed a Telegram bot that could host mini-games with a functioning internal economy where users earn and spend in-game balance. The system had to support real withdrawals, which meant anti-fraud protection was necessary from the start.

The challenge was building a reliable economy inside Telegram that could handle referrals, track balances accurately, prevent abuse, and process withdrawals without errors or exploitation.

Solution

We built a Telegram bot using Python and aiogram as the core framework. The mini-games run inside a Telegram Mini App, giving users a native in-app interface without leaving the messenger.

The internal economy is backed by PostgreSQL for persistent storage of balances, transactions and user data, with Redis handling session state and caching for fast reads. The referral programme tracks invites and rewards, while anti-fraud logic monitors patterns and flags suspicious activity before payouts.

Users can withdraw their in-game balance through the bot. The withdrawal flow includes validation, fraud checks and processing logic that connects to the payout mechanism. A community chat was set up alongside the bot to support users and build engagement.
