Q-Pay Bridging Merchants and Customers On Chain

Q-Pay is a next-generation decentralized Web3 payment and credit platform built on the Qubic network, designed to seamlessly connect merchants and customers through fast, secure, and transparent blockchain-powered financial interactions—without exposing users to the complexity of traditional crypto systems. Q-Pay allows businesses to accept cryptocurrency payments effortlessly using instant payment links and QR codes, making crypto transactions as simple as scan-and-pay. Through a clean and intuitive Merchant Dashboard, merchants create payment requests by entering the amount, asset type, and description. Each request generates a unique payment ID, a shareable link, and a QR code that opens a dedicated Customer Payment Interface optimized for clarity and usability. Customers interact with a minimal, user-friendly interface displaying merchant details, payment amount, and transaction summary. Upon payment confirmation (simulated for the hackathon), the transaction status updates from Pending to Paid, a timestamped digital receipt is generated, and confirmations are delivered to both parties. All transaction and merchant data are securely stored using a relational SQLite database, ensuring persistent history, transparency, and live dashboard visibility. Beyond payments, Q-Pay includes an integrated crypto credit and micro-loans module. Users can view credit limits, active debt, interest calculations, repayment amounts, and due dates, and request instant loans denominated in Qubic assets through a simple interface—creating a unified Pay + Credit experience. Q-Pay removes manual verification, reduces operational friction, and unifies payments, receipts, and credit into one decentralized flow. While simulated for the hackathon, the architecture is fully prepared for Qubic smart contract integration, enabling real on-chain settlements, immutable receipts, decentralized escrow, automated lending, and trustless repayments—accelerating real-world Web3 adoption.
