DEX aggregators search multiple DEXes to find the best execution price for your trade. They split orders across sources to minimize slippage and maximize output.
How Aggregators Work
- Query prices from multiple DEXes
- Calculate optimal routing
- Split order across sources if beneficial
- Execute with single transaction
Major Aggregators
- 1inch — Largest aggregator, Fusion mode for MEV protection
- Paraswap — Gas-optimized routing
- CoW Swap — Batch auctions, MEV protection
- 0x/Matcha — Professional-grade API
When to Use Aggregators
- Large trades (benefit from split routing)
- Illiquid tokens (aggregators find best sources)
- MEV protection needed
- Price discovery across DEXes
Key Takeaways
- Aggregators find the best price across DEXes
- Split routing reduces slippage on large trades
- Some offer MEV protection features
- Always compare quotes before large swaps
