I am looking for a skilled Python developer to build a Telegram Bot that automates the sale of Virtual Credit Cards (VCCs). This is a backend-heavy project with a "Zero-Touch" architecture. There is no website, no admin panel, and no third-party crypto gateway (like Cryptomus). The bot will interact directly with the blockchain and a Supplier API. The Workflow You Will Build: User Interface: Pure Telegram Bot (Commands & Buttons). Payments: The bot monitors a single USDT (TRC20) wallet. It identifies users by assigning "Unique Amounts" (e.g., asking User A to pay $10.01 and User B to pay $10.02). Fulfillment: Once payment is detected on-chain, the bot instantly forwards funds to the supplier via API and issues the card to the user. What I Provide: Complete Developer Documentation: I have a ready-made Google Doc explaining every endpoint, the logic flow, and the MD5 signature requirements. UI Mockups: Screenshots of exactly how the bot should look. API Keys: Access to the supplier environment. Requirements: Python: Expert level (Clean code, handled exceptions). Telegram API: Experience with python-telegram-bot or aiogram. Blockchain: Experience using tronpy or similar libs to monitor TRC20 transactions (Incoming/Outgoing). REST APIs: Comfortable with signing requests (MD5/Sorting parameters). Security is essential because of the cards data sensitivity nature To Apply (Anti-Spam Verification): Please do not send a generic cover letter. Start your proposal with the word "USDT-VCC". Tell me which Python library you prefer for monitoring Tron/USDT transactions. Confirm you are comfortable working without a UI/Dashboard (CLI/Log based only). Budget: Fixed Price (Review the docs attached before final quote).
