A fully developed decentralized exchange, similar to (coinex.com) and (hotcoin.com), featuring P2P, spot trading, contract trading, leveraged trading, etc I need a production-ready decentralized exchange built on Binance Smart Chain that can stand beside CoinEx and Hotcoin in both speed and depth of features. The platform must ship with every layer required for live deployment—smart contracts, matching engines, liquidity modules, back-end APIs, responsive web interface, and mobile-friendly front end—fully tested and security-audited. Core trading functionality is non-negotiable: • P2P trading • Spot trading • Contract (futures) trading • Leveraged trading Each module has to share a seamless account system, unified order book, and real-time market data. Fee tiers, referral links, and an admin dashboard for risk and treasury management should be baked in from day one. Wallet integration will center on BOCO. Please architect the wallet gateway so additional options such as MetaMask, Trust Wallet, or Binance Chain Wallet can be added without a hard rewrite. Performance targets: sub-second order execution, scalable to 50k+ concurrent users, and gas-optimized contracts that keep trading costs minimal. Security expectations include comprehensive unit tests, automated vulnerability scans, and at least one external audit report before hand-over. Deliverables are considered complete when I can: 1. Deploy the contracts and back end with a single set of scripts. 2. Connect through BOCO, deposit test funds, and complete trades in every listed mode. 3. View accurate balances, PnL, and liquidation events. 4. Run the exchange for 72 hours on a public testnet without downtime or critical errors. If you already maintain a DEX codebase or white-label solution on BSC, let me know; faster turnaround is a plus as long as ownership of source code and future upgrade rights remain with me.
