Bangladesh USDT Exchange Platform

I want to launch a full-featured cryptocurrency exchange focused on seamless USDT trading for users in Bangladesh. The core of the build must be rock-solid security and an intuitive, mobile-friendly interface that lets customers deposit, trade, and withdraw with local payment options such as bKash, Nagad, and standard bank transfers.

Security priorities
• Two-factor authentication on every sensitive action
• End-to-end encryption of all user data—both at rest and in transit

Please design the architecture so I can add cold-storage wallets or DDoS mitigation later without a major rebuild. An admin dashboard with user KYC management, fee settings, and transaction monitoring should ship with the first release.

Deliverables
• Complete source code (backend, frontend, and APIs)
• Deployment scripts and environment documentation (Docker or similar)
• Basic test suite proving 2FA flow, encrypted data storage, and trade execution
• Short hand-over guide so my local team can maintain and extend the platform

If you have prior experience building crypto exchanges or payment gateways in emerging markets, let me know—the nuances around local compliance and liquidity will be a big plus.
