We built the Scalpel landing, the Sprinter mini-app, a concierge bot and CRM inside Telegram — operations without a paid CRM.

Project site: thefour.pro

RUB↔THB/USDT cannot run from email. We built the ecosystem: Scalpel landing, Sprinter Telegram Mini App, a concierge bot, and a super-chat with statuses.

What shipped: a Uniswap-style calculator that opens the mini-app in one tap, a three-screen request, a concierge that parses “500 usdt thb”, and inline statuses in the super-chat.

Modules

The landing calculator behaves like Uniswap and opens the mini-app in one tap. The request is three screens. The concierge accepts a free-form phrase. The super-chat keeps statuses inline — no separate admin.

How the client earns

Spread plus courier and ATM in Thailand.

Numbers and stack

Budget $1000, ten to fourteen days. TypeScript, Next.js, Cloudflare Pages + Workers, SQLite.

The twist

All operations live inside Telegram, without a paid CRM.
