What is a Telegram Mini App and what APIs does it use?

A Telegram Mini App (TWA) is a web app that runs inside Telegram's 800M+ user base. It uses the Telegram Web App API with functions like `tg.ready()`, `tg.expand()`, `MainButton`, `BackButton`, `themeParams`, and `HapticFeedback` to integrate with Telegram's native interface.

How do I add TON blockchain wallet support to a Telegram Mini App?

Use TON Connect via the `@tonconnect/ui-react` library to enable wallet connection and TON transactions. You'll need to include a required `tonconnect-manifest.json` file and test on real devices with wallets like Tonkeeper or OpenMask, as TON Connect can fail on mobile due to manifest, HTTPS, or deep-linking issues.

What monetization options are available for Telegram Mini Apps?

You can monetize through TON payments, in-app purchases, Telegram Ads, referral programs, NFT sales, and Telegram Stars currency (`XTR`) for invoices.

Why is server-side initData validation critical, and how do I do it?

Trusting `initDataUnsafe` directly on the backend is a HIGH-severity security vulnerability that allows user spoofing and data tampering. Validate it server-side using HMAC-SHA256 hash verification against your bot token.

What are common performance issues in Telegram Mini Apps?

Slow or janky apps typically result from large bundle sizes, missing code splitting, or lack of lazy loading. Use native Telegram UI components like `MainButton` instead of custom buttons to maintain expected UX conventions and avoid performance degradation.

Overview

This skill guides Telegram Mini App architecture across the Web App API, TON, UX, authentication, and payments. The supplied overview points to a separate detailed guide rather than exposing implementation procedures. Use it for Telegram Mini App or TWA design. Validate actual client capabilities and payment rules, and clarify missing inputs or permissions before execution.

What it does

This skill takes the role of a Telegram Mini App Architect for web applications that run inside Telegram. Its stated scope covers the Telegram Web App API, Mini App UX, user authentication, payments, and the TON ecosystem. Additional topics include TON Connect, crypto payments, and viral mechanics.

The design should follow the capabilities of the actual Telegram client and the intended audience. Distinguish digital-goods Stars payments from other permitted payment or wallet flows. Telegram's overall audience is not evidence that a particular Mini App will attract users or earn revenue.

When to use - and when NOT to

Use it for a Telegram Mini App, TWA, Telegram web app, or TON app request that fits this scope. It supports architectural planning around those platform concerns. The overview does not provide working code, an installation command, a tested payment integration, or a deployment procedure.

Inputs and outputs

Before execution, the skill requires reading its separate detailed guide. Focused work should load the relevant sections, while end-to-end work should read the complete procedure and reference material. Those prerequisites and validation requirements remain mandatory; the supplied overview does not include their contents.

Required inputs, permissions, safety boundaries, and success criteria must be clarified when missing. Any resulting design or implementation still needs environment-specific validation, testing, and expert review where appropriate.
