Telegram Mini-App Development for Crypto Card Creation & Recharge (API provided)
1200 USD
Hello,
I'm looking for an experienced developer to build a Telegram Mini-App connected to my platform, which allows users to create virtual cards and recharge them using cryptocurrency.
🔧 What’s already in place:
A fully functional API (backend is live and working)
A working web interface
The full card creation and management flow is defined
🛠️ What the Telegram Mini-App should do:
User authentication via Telegram
Card creation via API
Display of crypto balances via API
Recharge of cards via API (no direct payments inside the mini-app)
eSIM integration (API also available)
Clean, responsive design aligned with Telegram Mini-App guidelines
📱 Goal:
Provide our users with a light, fast alternative to the web and mobile app — allowing them to create and manage their crypto cards directly from Telegram.
💬 Please share:
