I already have an Android Studio project that compiles, but the core money-making engine still needs finishing touches. The existing code handles login, basic UI, and wallet connectivity; what I am missing is the rock-solid execution layer that can: • Trigger real-time arbitrage trades between target exchanges • Open and settle flash loans on-chain within the same transaction • Run the whole sequence automatically, hands-free, once profitable spreads appear To achieve this you will need to wire in reliable financial data APIs for live prices, complete the trading/loan logic, and harden the scheduler with proper error handling and retries. Clean, well-commented Kotlin (Java is acceptable) is a must. Deliverables - Reviewed and refactored source so it follows Android best practices - Integrated price feed via my chosen financial data API(s) - Fully functional arbitrage + flash-loan module, callable from the current UI - Automated execution engine with configurable thresholds and safety checks - End-to-end test cases proving successful loan, trade, and repayment in a single run - Final signed APK and updated source in Git I will supply the current Git repo, API keys, and exchange credentials. If you have previous DeFi, Web3j, or ethers-android experience that will be a plus, but solid Android and REST/WebSocket know-how is essential. Let’s get this app ready for production.
