I need a production-ready crypto trading bot purpose-built for advanced users who already understand market micro-structure and are looking to exploit price inefficiencies across multiple venues. The core strategy is multi-exchange arbitrage, so speed, reliability and smart order-routing matter more than beginner-level hand-holding. Scope of work I want a single code-base (Python with CCXT or an equivalent low-latency stack is fine) that can simultaneously connect to Binance, Coinbase and Kraken through both REST and WebSocket feeds, monitor order books in real time, calculate spread opportunities after fees, and place hedged orders fast enough to lock in profit. The architecture should be modular so I can later drop in additional exchanges without rewriting the whole engine. Key requirements • Secure API key management and encrypted credential storage • Real-time market data aggregation with millisecond-level latency targets • Configurable risk parameters (max exposure per trade, per exchange limits, kill-switch) • Robust error handling and automatic re-sync if a WebSocket stream drops • Comprehensive logging plus an analytics dashboard or exportable metrics so I can review performance Deliverables • Fully functioning arbitrage bot ready to run on a VPS or Docker container • Clean, well-commented source code and setup script • Quick-start guide explaining configuration, deployment and how to add new exchanges • A short report (or notebook) demonstrating back-test or live dry-run results over at least 48 hours on the three specified exchanges Acceptance criteria • Bot executes live arbitrage cycles across Binance, Coinbase and Kraken with end-to-end latency under one second • All trades respect the configurable risk parameters and conclude with balanced positions across the exchanges • No unhandled exceptions during a 24-hour continuous run in a test environment • Code passes a brief review for readability and modularity If you have previous experience building high-frequency or cross-exchange crypto systems and can meet the above targets, I’d love to see your proposal along with any relevant repo links or performance metrics from past projects.
