Introduction
The DeFi market experienced exponential growth in late 2020, fueled by liquidity mining incentives. Key sectors like lending, decentralized exchanges (DEXs), asset management, stablecoins, and aggregators have formed an interconnected ecosystem. Among these, DEX aggregators have emerged as critical infrastructure for optimizing trade execution across fragmented liquidity pools.
This report analyzes leading DEX aggregators—platforms that consolidate price quotes from multiple DEXs to ensure users obtain the best asset swap rates. We focus on 1inch (V1/V2) and 0x, examining over 810,000 historical transactions to uncover:
- Market trends in aggregated trading
- Algorithmic differences in price discovery
- Protocol-specific execution preferences
Key Findings
1. Market Concentration
- Uniswap and Sushiswap dominate 68% of DEX volume
- Niche protocols like Curve and 0x handle >$250M daily
- Aggregators solve liquidity fragmentation by routing trades optimally
2. Transaction Patterns
- 72% involve ETH or stablecoins (USDT/USDC/DAI)
- Small trades (<10 ETH) prevail on 0x
- Mid-size trades (1–500 ETH) dominate 1inch
3. Execution Strategies
| Metric | 0x | 1inch V1 | 1inch V2 |
|---|---|---|---|
| Splits | 5.8% | 29% | 23% |
| Routes | 26% | 73% | 71% |
- Splits reduce slippage; routes bypass shallow pools
- Complex paths (split → route) yield best prices
4. Gas Fee Optimization
- 1inch V2 averages higher fees but better execution
- Each additional route increases costs 2.3× vs. splits
5. DEX Preferences
- Uniswap is most-called (60% of routes)
- Curve usage spikes for stablecoin trades
FAQ
Q1: Why use aggregators over direct DEX trading?
Aggregators scan multiple DEXs in one transaction, minimizing slippage and manual effort—especially for large trades.
Q2: Which protocol suits small traders?
0x excels for sub-0.5 ETH trades with lower gas costs.
Q3: Does 1inch favor long-tail assets?
Yes. Its algorithms aggressively split orders for illiquid tokens.
Q4: How do aggregators impact DeFi’s future?

Conclusion
DEX aggregators fill a vital niche as DeFi’s application layer, mitigating liquidity fragmentation. While 1inch and 0x currently show similar algorithmic efficacy, their specialization (1inch for complex routes, 0x for gas efficiency) hints at future market segmentation.
For traders, the choice hinges on:
- Asset type (mainstream vs. exotic)
- Trade size
- Gas budget
As DeFi matures, expect aggregators to deepen integration with lending/derivatives platforms—further blurring CeFi/DeFi boundaries.
