Centralized USDT-INR OTC Crypto Exchange

You can send this directly to your developer: I want to build a website similar to [login to view URL] with a centralized USDT-INR OTC exchange system. The platform should allow users to: * Buy USDT using INR * Sell USDT for INR * Deposit INR * Withdraw INR * Deposit USDT (TRC20) * Withdraw USDT (TRC20) The platform should work as a centralized custodial wallet system where admin controls all wallets and balances internally. Users should NOT control private keys. All user balances should be stored and managed using an internal ledger/database system. Main Website Features User Features Authentication * Mobile OTP login * Email login * 2FA support ⸻ Dashboard Users should see: * INR balance * USDT balance * transaction history * deposit/withdrawal history ⸻ Buy USDT User enters INR amount and receives USDT balance based on admin-set exchange rate. ⸻ Sell USDT User sells USDT and receives INR balance based on admin-set exchange rate. ⸻ INR Deposit User submits: * UPI payment * bank transfer reference/screenshot Admin manually approves deposit. ⸻ INR Withdrawal User submits: * bank account or UPI ID * amount Admin manually approves withdrawal. ⸻ USDT Deposit Generate TRC20 deposit address for users. System should automatically detect incoming blockchain deposits and credit balances after confirmation. ⸻ USDT Withdrawal User enters: * TRC20 wallet address * withdrawal amount Admin manually approves and processes withdrawal. ⸻ Referral System Users should have: * referral code * referral commission tracking * agent system support ⸻ IMPORTANT ADD-ON FEATURE (HIGH PRIORITY) I want a SUPER ADMIN wallet management feature. Admin should have full control over all user wallets and balances. Super Admin Features Admin should be able to: * access any user wallet * manually edit balances * deduct/add USDT balance * deduct/add INR balance * freeze/unfreeze user accounts * approve/reject withdrawals * transfer user funds internally * send USDT to ANY external wallet address manually * manage master treasury wallet * override withdrawal system * monitor all wallet transactions ⸻ Admin Withdrawal Control System Admin should have an option inside admin panel: “Send USDT Manually” Admin enters: * wallet address * amount System sends USDT from master wallet. ⸻ Internal Wallet Control The system should be fully custodial. Meaning: * admin/server controls all private keys * users only see balances internally * blockchain funds stay in centralized treasury wallets ⸻ Wallet Architecture Need: * centralized hot wallet * internal balance ledger * treasury management system * transaction logs * withdrawal approval system Preferred blockchain: * TRON TRC20 ⸻ Admin Dashboard Requirements Admin panel should include: * total INR liquidity * total USDT liquidity * total users * pending withdrawals * pending deposits * profit/spread tracking * user activity logs * wallet activity monitoring * referral commission management ⸻ Technical Stack Frontend: * React.js / [login to view URL] Backend: * Node.js + NestJS OR Laravel PHP Database: * PostgreSQL or MySQL Blockchain APIs: * TronGrid * Tatum * QuickNode ⸻ Security Features Need: * 2FA * encrypted private keys * admin audit logs * withdrawal confirmation * IP/device tracking * role-based admin access * rate limiting ⸻ Final Goal The platform should function similar to [login to view URL]: * centralized OTC exchange * internal balance system * admin-controlled wallet infrastructure * gaming fund compatible workflow * scalable for agents and high-volume traders Main priority: * fast transactions * admin wallet control * liquidity management * referral/agent growth system
