# What is DEX Aggregation? Complete Guide to 1inch and Paraswap 2025

DEX aggregation is revolutionizing how traders find the best prices across decentralized exchanges. Instead of manually checking multiple DEXs, aggregators like 1inch and Paraswap automatically split your trades across multiple platforms to minimize slippage and maximize returns.

## What is DEX Aggregation?

### Core Concept
DEX aggregators are smart routing protocols that scan multiple decentralized exchanges simultaneously to find the optimal trading path for your transaction. They can split a single trade across multiple DEXs and routes to get you the best possible price.

### How Aggregation Works
1. Price Discovery: Aggregator scans all connected DEXs for current prices
2. Route Optimization: Algorithm calculates the best combination of exchanges
3. Trade Splitting: Large orders are split across multiple pools
4. Gas Optimization: Routes are optimized for both price and gas costs
5. Execution: All trades are executed atomically in a single transaction

## How to Use DEX Aggregators

### Step-by-Step Guide

Using 1inch:
1. Visit app.1inch.io
2. Connect Wallet (MetaMask, WalletConnect, etc.)
3. Select Network (Ethereum, Polygon, BSC, etc.)
4. Choose Tokens for swap
5. Review Routes and gas estimates
6. Adjust Slippage if needed
7. Execute Swap and confirm transaction

Advanced Settings:
– Slippage Tolerance: 0.1-3% depending on volatility
– Gas Price: Adjust for faster/cheaper execution
– Partial Fill: Allow partial order completion
– Route Customization: Include/exclude specific DEXs

### Best Practices
– Compare Aggregators: Different aggregators may offer better routes
– Check Gas Costs: Factor in transaction fees
– Timing Matters: Trade during low congestion periods
– Use Limit Orders: For non-urgent trades
– Monitor Routes: Understand where your trades are being executed
