@technosystem

As an experienced blockchain developer, I am confident in my ability to create a robust and efficient multi-exchange crypto arbitrage system to meet your needs. With my extensive proficiency in API integration, Software Architecture, C++, C#, and C Programming, I can assure you of a modular system that can easily accommodate further exchanges should the need arise. I have successfully deployed decentralized (DEX) and centralized (CEX) exchanges before, which have given me in-depth knowledge of market dynamics and trading logic. Combining this with my understanding of Solidity smart contract programming, I am equipped to handle the complexity of your project, including the development of the Core Engine that supports various arbitrage strategies like Cross-Exchange Arbitrage, Spot-Futures Arbitrage, and Funding Rate Arbitrage. Moreover, I understand the need for stringent risk management measures. Mitigating these risks effectively has been crucial in all my past projects inclusive of API disconnect handling, Partial fill protection, Slippage control, Margin monitoring, Liquidation monitoring among others.

@BrainstackTech

Hello there, We have around 8 years of rich experience in real-time trading systems, API integration, and data pipeline architecture. The core challenge in your multi-exchange arbitrage system isn't the strategy logic — it's executing both legs simultaneously across exchanges with sub-second latency while accounting for partial fills, slippage, and the reality that orderbook depth changes between when you see the spread and when you hit it. For the real-time price ingestion layer, we'd use Python with asyncio and WebSocket connections to all five exchanges (Binance, Kraken, Bybit, OKX, Bitget) via ccxt pro — it's the only library that normalizes WebSocket feeds across exchanges without writing custom adapters for each. The screener dashboard ranking spreads from highest to lowest would run on FastAPI with Server-Sent Events pushing updates to a React frontend. No polling. Price data hits your screen in under 200ms from exchange. For the profit calculation engine — maker/taker fees, funding impact, borrowing costs, slippage estimation — we'd build a preprocessing pipeline that normalizes each exchange's fee structure into a unified model, then runs spread calculations through a chain: raw spread → net spread after fees → estimated profit after funding → final ROI%. This is where most arbitrage tools break down. They show gross spreads that vanish once you factor in the actual execution costs. We'd cache fee schedules and funding rates with short TTLs to avoid hammering rate limits while keeping calculations accurate. On risk management: API disconnect handling and exchange downtime detection would use a heartbeat monitor per connection. If a WebSocket drops mid-trade, the system freezes that leg and triggers the auto-hedge logic you described. Partial fill protection works through a state machine — every trade lives in a defined state (pending, partial, filled, hedging, closed) with transitions that prevent orphaned positions. We've built production trading analytics dashboards and real-time data platforms processing millions of events daily. The subscription model you mentioned (₹5-10k/month) means this needs to be rock-solid for paying users — our experience building multi-tenant SaaS platforms directly applies here. Happy to share an architecture diagram showing the WebSocket ingestion, spread calculation pipeline, and execution flow. We'd break this into four phases: exchange connectivity + data normalization (weeks 1-3), screener dashboard + profit engine (weeks 4-6), trade execution with risk management (weeks 7-9), and testing + hardening (weeks 10-12). Weekly demos so you see progress in real time. Looking forward to hearing from you. Naveen Brainstack Technologies
