FREEBLOCK / TELEGRAM MINI APPS
Telegram crypto wallet
development
A financial product inside Telegram, from sign-in and balances to transfers and support. We build the Mini App, backend and team tools around a coherent user journey.
Share an idea or existing screens. We’ll define the first release together.
01 / YOUR PRODUCT
A wallet where your users already are
For teams that need their own wallet interface and product logic in Telegram. We select the Mini App format together with the custody model.
A new product
Sign-in, wallet operations and support without a separate mobile app. Define the first release before designing screens.
A fintech distribution channel
Connect a Mini App to your existing backend with consistent balances, operations and permissions.
An existing wallet
Improve user journeys, add operations and operator tools, and fix confusing interface states.
02 / DELIVERY SCOPE
From opening the bot to completing a transfer
The MVP covers one complete journey. Cards, swaps, referral features and additional networks are scoped as separate modules.
-
Sign-in and profile
Server-side Telegram initData validation, sessions, profile settings and additional access checks.
-
Wallet dashboard
Assets, balances, history and loading states, with a clear distinction between available and pending amounts.
-
Receive and send
Payment details, QR codes, recipient validation, fees and action confirmation.
-
Backend and bot
Operation APIs, permitted notifications, error handling and support integration.
-
Administration
User and transaction lookup, support requests, staff roles and activity logs.
03 / DESIGN DECISIONS
Decisions before the first screen
- Custody or wallet connection
- Telegram sign-in does not define who manages the keys. Choose service-side custody or an external wallet connection for your product.
- Telegram platform rules
- Blockchain features in Mini Apps must account for Telegram’s TON and TON Connect requirements. Digital goods payments inside Telegram require a separate review of Telegram Stars rules.
- Existing systems
- Agree on APIs, the balance source, statuses, recovery and ownership of each operation, including provider restrictions.

Designed for real user journeys
A historical case demonstrates delivered work. It does not replace a review of current platform restrictions. We agree on networks, operations and providers before implementation.
- Test launch, return from an external wallet and screen restoration.
- Account for the keyboard, safe areas and small devices.
- Make pending, failed and retry states clear without repeating operations.
- Check light and dark themes, accessible actions and readable amounts.

08 / FAQ
Before we start
How is a Mini App different from a Telegram bot?
A Mini App opens a full web interface inside Telegram. The bot can launch it, send messages in permitted scenarios and support customer interactions.
Can you connect our existing backend?
Yes. We review authentication, balance and operation APIs, restrictions and the test environment, then specify missing methods and error handling.
Which blockchains can it use?
Telegram Mini App blockchain features are subject to platform requirements around TON and TON Connect. We review the proposed architecture against current rules before agreeing on scope.
Can we add swaps and bank cards?
These are separate integrations. Availability depends on provider APIs and terms, supported countries and the product model. We confirm feasibility before promising features.
Does it need a custom smart contract?
Not every scenario does. We first separate on-chain logic from backend operations and accounting, then include custom contracts only where needed.
How do you estimate development?
We scope the Mini App interface, backend, bot, integrations, operator dashboard and testing separately, then define the MVP and later phases without a universal tariff.
