Multi Exchange Crypto Arbitrage Bot

I need a real-time crypto arbitrage bot that can interact with all possible exchanges—starting with Binance, Coinbase, and Kraken, and expanding to any other venue that exposes a usable API. The bot must continuously compare order books, highlight profitable spreads, execute the corresponding buy/sell orders automatically, and keep an accurate running tally of every gain or loss.

I am not tied to a specific stack; use whatever you judge to be best for speed, reliability, and easy maintenance. Just keep the code modular so I can plug in additional exchanges later without a rewrite.

Deliverables
• Fully-functional bot with modular exchange adapters
• Configurable thresholds for spread size, trade size, and per-exchange toggles
• Persistent logging of detected spreads, executed trades, and cumulative P&L
• Clear setup guide including key management instructions and example configs

Acceptance criteria: during a 24-hour test the program must detect at least three live spreads, execute at least one real trade when keys are provided, and record the result correctly in the P&L log. If you can meet those marks with the stack you believe is best, let’s get started.
