In this video, we build a Telegram product-selling bot that can accept Solana payments and automatically deliver digital products like photos, videos, documents, ZIP files, and other media directly inside Telegram. This is not a simple echo bot. This is a real product-style Telegram bot where: ✅ Admin can upload digital products ✅ Products are saved with price, description, and media type ✅ Users can browse products inside Telegram ✅ The bot generates a unique Solana payment request ✅ Payment is tracked using a unique reference/order ID ✅ After payment confirmation, the bot automatically delivers the purchased media ✅ Refund/support flow is also planned ✅ Mock payment flow is added for local testing We use TypeScript, grammY, PostgreSQL, Drizzle ORM, Solana payment links, and Codex/AI coding to build the application step by step. The video also shows how AI coding tools are useful, but also why we still need to guide, test, debug, and improve the generated code. Solana Pay supports payment URLs, QR codes, and unique references for tracking payments, which fits this bot’s payment design very well. grammY is also a strong TypeScript/JavaScript framework for building Telegram bots, and grammY runner helps with concurrent bot processing. This tutorial is useful if you want to build Telegram bots, crypto payment bots, digital product delivery bots, or learn how to vibe code a real-world application with AI tools.
