Okay, building a bot to automatically find and calculate cryptocurrency arbitrage opportunities between Iranian exchanges is a complex task, especially within this browser-based environment. Here's why and what we *can* set up as a starting point: **Challenges:** 1. **API Access:** Getting reliable, real-time API access to *multiple* Iranian exchanges can be difficult. Documentation might be limited, in Persian, or require specific registration/verification. Public APIs might not exist or might have strict rate limits. 2. **Real-time Data:** Arbitrage opportunities often last only seconds. Fetching data from multiple sources quickly and reliably is crucial. Network latency can be a significant factor. 3. **Fees:** Accurate calculation *must* include trading fees (maker/taker), withdrawal fees for the specific cryptocurrency, and potentially deposit fees. These vary between exchanges. 4. **Execution (Not Included):** This request is for *calculation*, but a real arbitrage bot would need to *execute* trades automatically, which adds layers of complexity (API key management, order placement logic, error handling, security). 5. **WebContainer Limitations:** This environment isn't ideal for long-running, persistent bots that need constant network access. A server-side application would be more suitable for a production-level bot. CORS (Cross-Origin Resource Sharing) policies on the exchange APIs might also prevent the browser from directly fetching data. **What We Can Build (A Framework/Simulator):** We can create the *structure* of such a tool. It will include: * A configuration file for exchanges, pairs, and fees. * Placeholder functions for fetching data (you'll need to replace these with actual API calls). * Logic to compare prices and calculate potential arbitrage rates. * A simple interface to trigger the check and display results. **This will NOT connect to real exchanges out-of-the-box.** You would need to research the specific APIs for the Iranian exchanges you want to use and implement the data fetching logic yourself.

Note: This is a framework. Real API connections need to be implemented in api/ files. Fee data in config.js must be accurate. Arbitrage carries significant risk.
