Problem

Building on Telegram comes with its own set of technical challenges

Challenge: No Native MetaMask Support in Telegram

Unlike browser-based web apps, Telegram Mini Apps don’t support native MetaMask integration out of the box. Users couldn’t connect their crypto wallets other than TON — a significant blocker for verifying token ownership and boosting in-app rewards.

Challenge: Verifying Real User Actions on Social Media

Most Telegram quest-based apps only simulate user interactions — for example, they’ll open Instagram or X (Twitter), but can’t actually check if a user followed or reposted something. This limits authenticity and opens the door to abuse.

Solution

Our Solution:

We researched multiple open-source approaches, tested compatibility across platforms, and adapted the most reliable method for the Telegram environment. The result was a custom wallet verification flow that integrates with the MetaMask mobile app and enables token-based boosts inside the mini app.

Our Solution:

We discovered and integrated KAZM, a third-party tool that verifies real user actions across social platforms. This allowed us to confirm actual follows, likes, reposts, and more — making social tasks meaningful, verifiable, and reward-worthy.

Product Tech Stack

Innovative Tools Powering Our Solutions

Telegram Mini-App Interface

Built with Next.js, React 18, and TypeScript, the mini app delivers a fast, modern experience right inside Telegram.
We used Webpack for optimized builds and React Context for state management across components.
The app is fully responsive and designed to feel native across both mobile and desktop Telegram environments.

Frontend Logic & Blockchain Integration

API communication is handled via Axios, enabling seamless interactions with the backend.
For Web3 integration, we used Wagmi and Viem libraries to manage wallet connections and smart contract interactions.
TON Wallet Connect was embedded for users to link wallets and earn boosts without leaving Telegram.

Backend & Telegram Integration

The backend is built on Django and Django REST Framework, handling user auth, replica data, and quest mechanics.
Celery and Redis process background jobs and asynchronous tasks, while Telegram Bot API handles real-time interactions and UI triggers.
Web3.py connects with blockchain networks to verify token ownership and apply reward logic.

Infrastructure & Data Layer

User and platform data is stored in PostgreSQL, designed for scalability and structured around quests, users, and replica stats.
Redis supports fast data access and caching for leaderboard and game logic.
All async tasks like airdrops and reward calculations are managed through Celery, ensuring responsive performance even during high loads.
