I need a full-stack developer (or team) to create an instant buy-and-sell platform for USDT that feels as smooth as any modern fintech app. The site must allow customers in India to purchase or liquidate USDT with UPI, bank transfer, IMPS, or even cash deposit, then push the funds straight to their TRC20 or BEP20 wallet within seconds. Website want like this ---> [login to view URL] Core flow 1. Visitor chooses Buy or Sell 2. Enters amount and picks a payment rail 3. Completes the transfer 4. Receives USDT (or INR) instantly Key requirements • Authentication: simple email verification during sign-up, with the code auto-expiring after five minutes. • UI: modern, sleek, fully responsive design—no dated templates. • Speed: the matching engine and payment callbacks need to clear in real time; target sub-10-second round-trip from payment confirmation to wallet transfer. • Rates: the exchange module has to fetch live market pricing and apply our configurable margin. • Wallets: built-in hot-wallet handling for TRC20 and BEP20, plus a cold-storage sweep script. • Support: ticket and live-chat module so my team can provide 24/7 assistance. Security features to bake in - End-to-end encryption of all sensitive user data at rest and in transit - Active anti-fraud rules (velocity checks, blacklists, device fingerprinting) - Always-on DDoS protection and rate limiting Deliverables • Complete source code (front-end, back-end, smart-wallet scripts) • Deployed staging and production environments with CI/CD • Admin dashboard for KYC review, treasury monitoring, fee settings, and audit logs • Technical documentation and a quick-start guide for my support staff • Post-launch bug-fix window Tech stack is flexible, but I am leaning toward React or Vue for the front end and Node.js, Go, or Laravel for the API—use what you can secure and scale. The finished site must pass penetration testing, handle at least 1,000 concurrent users without lag, and clear a series of sandbox USDT transfers before final sign-off. If you have proven crypto-exchange experience and can bring this live quickly, let’s talk.

Hi, I understand exactly what you’re aiming for—a real-time, user-friendly USDT buy/sell platform for Indian users that mirrors modern fintech apps like Gaspe. I can build a secure, full-stack solution with React or Vue on the front end and Node.js or Go on the backend, integrating live market rates, UPI/bank transfers, and TRC20/BEP20 wallet payouts. I’ll ensure sub-10-second transaction flows, hot/cold wallet management, anti-fraud measures, and an admin dashboard for treasury and KYC oversight. The code will be clean, fully documented, and production-ready with CI/CD pipelines and post-launch support. Looking forward for your positive response in the chatbox. Best Regards, Arbaz Ali
