1inch is the reference multi-chain DEX aggregator for EVM ecosystems. Aggregates 400+ liquidity sources, offers MEV-protected Fusion mode, and provides institutional-grade execution across 12+ chains. Essential for anyone doing meaningful EVM swaps.
How 1inch works
1inch queries every meaningful DEX and RFQ liquidity source across supported chains, then routes your swap through the best-execution path (often splitting across multiple venues). Users see one quote; 1inch handles complexity.
Fusion mode:
An intent-based execution mode where resolvers compete to fill your order. Resolvers absorb MEV; users get better prices without sandwich attack exposure. This is 1inch's most differentiated feature.
Fees
- 1inch fee: zero on standard swaps (revenue from resolver auctions in Fusion)
- DEX fees: pass-through from underlying protocols
- Gas: user pays chain gas
Where 1inch dominates
- Multi-chain aggregation (12+ EVM chains)
- MEV protection via Fusion
- Deepest liquidity source coverage (400+ DEXs)
- Clean UX for both retail and pro traders
Verdict
1inch is the reference EVM DEX aggregator. Fusion mode is one of DeFi's strongest MEV protection stories. For any EVM swap where MEV matters, 1inch should be your first check.
