In most arbitrage bots, everything is bundled: signal, logic, execution. This makes them fast — but also fragile. One wrong signal, one bad route, and the system collapses on itself. TYKO is built differently.We separate signal generation from execution. It’s not just architecture — it’s strategy.What Are the Two Layers?The Signal Layer is where opportunity is discovered.It monitors on-chain price flows, cross-DEX spreads, token depth, and MEV data. It’s designed to scan wide and fast — prioritizing detection over precision. The Execution Layer is where trades actually happen.It receives only high-confidence, filtered signals, then simulates them through profit, gas, and timing logic. If all criteria are met, it routes and executes. If not, the trade is dropped — instantly.Why the Split MattersSeparating these layers gives TYKO a structural edge:1. No False ExecutionsWhen signal and execution are fused, weak signals often trigger bad trades.TYKO avoids this by only allowing filtered, back-tested signals to reach the router.2. Faster Signal UpdatesSignals can evolve independently of routing logic.We can iterate on scanning speed, add new detection types, or plug into external APIs — without touching the execution core.3. Redundancy & Fault ToleranceIf the signal layer fails or becomes noisy, the execution engine remains untouched.If routing logic updates, signals remain stable. This decoupling prevents cascading failures.4. Scalability & ModularityWe can deploy multiple signal engines in parallel — some focused on stablecoins, others on volatile altcoins — while all feed into the same core execution engine.This makes TYKO modular by design.Inspired by How Real Trading Desks WorkTraditional quant firms don’t let signal generators execute trades directly.They separate alpha from routing. TYKO follows the same principle — because DeFi is a battlefield, and strategy matters as much as speed.What This UnlocksWith this split architecture, TYKO is future-proof. It allows us to:Plug in external alpha feeds (e.g., whale movement, on-chain sentiment)Run multiple strategy layers (e.g., Flash Loan Arbitrage, MEV Capture, CEX-DEX Spread)Deploy a Smart Execution Governor (SYRA) that decides which signal gets routed, and whenThe result: higher ROI, fewer losses, faster iteration, and scalable growth.We’re raising $550K to further expand and modularize TYKO’s execution stack. → Pitch website→ Pitch deck
