How Odos and CoW Swap differ on routing, chains and what they’re best at.
| Odos | CoW Swap | |
|---|---|---|
| Category | DEX aggregator | DEX aggregator |
| Type | Smart router | Batch auction |
| How it works | Optimizes routing across the joint surface of many tokens, enabling multi-input/multi-output swaps (e.g. swap A+B+C into D+E in one transaction) over 900+ liquidity sources. | Batches all orders into a ~30s auction; solvers compete to find the settlement that maximizes total surplus, with uniform clearing prices and Coincidence-of-Wants that eliminate sandwich MEV. |
| Chains | 16 | Ethereum, Gnosis, Arbitrum, Base |
| Highlight | Multi-in/out · 900+ sources | ~22% of ETH aggregator volume |
| Best for | Complex multi-token swaps | Large trades + MEV protection |
Pick Odos for complex multi-token swaps; pick CoW Swap for large trades + mev protection.
