I keep several accounts across Binance, Coinbase, Kraken, Crypto.com 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.
