# Aggregator Engine

### **What Is an Aggregator Engine?**

A DEX aggregator is a smart routing system that scans multiple decentralized exchanges simultaneously to find the most efficient trading route for your swap.\
Instead of relying on a single DEX’s liquidity pool, SpurSwap’s Aggregator Engine connects to **multiple DEXs and liquidity sources** at once, optimizing for price, speed, and cost.

When you initiate a swap, the engine:

1. Analyzes token prices across connected DEXs.
2. Splits or routes your trade through one or more exchanges.
3. Automatically selects the path that gives you the **best overall return**.

***

### **How It Works**

SpurSwap’s Aggregator Engine follows a multi-step optimization process:

1. **Token Pair Discovery**\
   The engine identifies all available trading pairs for the selected tokens on each connected DEX.
2. **Price and Liquidity Analysis**\
   It then queries each source for:
   * Token reserves
   * Liquidity depth
   * Current market price
   * Estimated gas costs
3. **Route Optimization**\
   Using an internal algorithm, SpurSwap simulates every possible swap path, including split routes and determines the most profitable and stable option for you.
4. **Execution Layer**\
   The engine executes the optimized route through smart contracts or API calls, ensuring your transaction finalizes securely and transparently on-chain.

### **Supported Liquidity Sources**

SpurSwap currently integrates with top decentralized exchanges and liquidity hubs, including:

* **PancakeSwap (BSC)**
* **ApeSwap (BSC)**
* **Uniswap V3 (Ethereum & Base)**
* **SushiSwap (Multichain)**
* **QuickSwap (Polygon)**
* **BaseSwap (Base Chain)**

The Aggregator Engine continuously evolves, new DEXs are added as the ecosystem grows to maintain optimal liquidity coverage.

### **Dynamic Price Routing**

Instead of using static APIs or hardcoded pairs, the Aggregator Engine dynamically queries live DEX data every time a swap request is made.\
This ensures that prices reflect **real-time market conditions**, not cached or outdated data.

The routing algorithm considers:

* Best token-to-token rate
* Gas efficiency
* Liquidity depth
* Historical volatility
* Potential price impact

This makes every swap decision **data-driven**, not guesswork.

### **Fail-Safe & Recovery Logic**

In the event that a preferred DEX route becomes unavailable during execution (for example, if liquidity temporarily drops), the Aggregator Engine automatically retries using the **next-best available route** without user intervention, minimizing swap failures and improving transaction reliability.

### **Why It Matters**

Traditional DEX users often overpay without realizing it, simply because they trade on a single platform.\
SpurSwap eliminates this inefficiency by letting users **access the entire DeFi liquidity network from one interface**, automatically choosing the most profitable route.

This means:

* No manual comparison between DEXs
* No need to understand complex routing logic
* Always getting the **best execution price**
