I keep several accounts across Binance, Coinbase, Kraken, [login to view URL] and Bitpanda and would like a single, lightweight program that lets me act from one place without ever logging in to the exchanges themselves. Once I paste an API key for any of those platforms, the tool must let me see balances, place or close trades, trigger deposits when supported, and initiate withdrawals—all through secure, full-access (read and write) calls. Language or framework is up to you; Python or Node.js would fit nicely but I am open if you can achieve the same stability and speed elsewhere. Security is critical: keys need to be encrypted at rest, requests signed exactly as each exchange requires, and rate-limits respected so nothing gets throttled. Deliverables • Source code with clear, in-line comments • A short configuration guide explaining where to drop each exchange key and how to run the app • Demonstration of successful trade, deposit and withdrawal on at least one sandbox or small-fund account per exchange If the above is clear and you have prior experience with multi-exchange API work, let’s get this built.

Hello, I’m Shagun, a backend developer specializing in custom API development and financial/trading systems integrations. I will build your Multi-Exchange Trading API Tool that allows you to connect with multiple exchanges, ingest market data, and execute trading operations through a single unified interface. This solution will include secure connections, real-time or near-real-time data handling, normalized response structures, and dependable order execution logic. My approach: ✔ Unified API Layer: Create a consistent REST/WebSocket API that interacts with each exchange’s native endpoints (REST for orders + WebSockets for live market data). ✔ Modular Exchange Connectors: Each exchange integration will be encapsulated as a module so you can easily add/remove exchanges later. ✔ Real-Time Data Sync: Normalize order books, ticks, and instrument data across exchanges for consolidated access. ✔ Order Execution Logic: Securely send limit/market orders, modify/cancel orders, and handle confirmations & errors with robust retry and logging. ✔ Security & Key Management: Store and manage API keys securely with encryption and rotation support. ✔ Documentation & Testing: Clear API docs and automated tests (unit + integration) for easy maintenance.

Hi, I’m a backend developer with solid experience building secure multi exchange trading tools using full access APIs. I have previously delivered dashboards and automation scripts that unified Binance, Coinbase, Kraken and other exchanges into a single control layer for balance tracking, order execution, and withdrawals. I understand the differences in signing methods, rate limits, and permission scopes across exchanges and how critical it is to handle them correctly. For your project, I will build a lightweight, secure tool that lets you manage all supported exchanges from one place without logging into their platforms. API keys will be encrypted at rest, requests will follow each exchange’s exact signing requirements, and rate limits will be respected to avoid throttling. The final delivery will include clean, well documented source code, a clear setup guide, and live demonstrations of trades, deposits, and withdrawals using sandbox or low balance accounts. The focus will be reliability, security, and maintainability. Best regards, George
