Hi there, I will build your INR-to-USDT direct buy and sell platform with full KYC onboarding, live rate display, payment gateway integration for INR deposits, and automated blockchain-based USDT transfers. The app will include a complete admin panel where your team can approve KYC requests, set buy and sell rates, manage USDT liquidity, monitor all transactions in real time, and pause operations when needed. For the transaction engine, I will implement a queue-based processing system with blockchain confirmation listeners so buy and sell orders execute reliably even under heavy load. Each transaction will carry automatic retry logic for failed or delayed transfers, and users will receive real-time status updates as their order moves from payment received through processing to completed. I will also build in configurable daily and monthly user limits along with a risk disclosure flow before the first transaction. Questions: 1) Which payment gateway are you planning for INR collection — Razorpay, Cashfree, or another? 2) Should USDT transfers support TRC-20, ERC-20, or should the user choose the network? 3) Do you have a KYC verification provider in mind, or should I integrate one like Digio or HyperVerge? Looking forward to talking through the details. Kamran

I understand you require a secure India-based app for direct INR to USDT buying and selling, with user KYC, live rates, and transaction tracking, all managed by the company’s liquidity. You need both buy and sell flows integrated with payment gateways and blockchain confirmations, along with an admin panel for KYC approval and transaction monitoring. With over 15 years of experience and 200+ projects completed, I specialize in PHP backend development and mobile app development using React Native and Flutter, which perfectly suits your need for iPhone and Android platforms. My experience with payment gateway integration, blockchain APIs, and security protocols aligns well with your requirements for a compliant and robust crypto platform. I will build the app using a secure API-driven architecture, integrating live USDT pricing and payment gateways for smooth INR transactions, while implementing KYC workflows and real-time transaction status updates. The admin panel will be designed for efficient liquidity management and risk controls. A realistic timeline for delivery would be around 8-10 weeks, ensuring thorough testing and compliance checks. Feel free to reach out so we can discuss your project in more detail and align on next steps.
