Astro was a Telegram Mini App that sold Telegram Stars and Premium at a discount. A user picked Stars or Premium, entered the recipient, paid in TON, by card or through CrystalPay at a live exchange rate, and the order was fulfilled through the Fragment API. It ran from March to June 2025.

I founded it and built all of it: the Next.js Mini App, its API routes for pricing, payment checks and withdrawals, the Python bot that opened it, and the MongoDB models behind users and transactions. Partners earned 5% of every referred purchase and withdrew it in TON. I archived it in June 2025.
