Odos: Multi-Input DEX Aggregator
+100 XP · 8 min read · Updated March 2026
What is Odos?
Odos is the first DEX aggregator to support multi-input, multi-output token swaps. Instead of making three separate swaps to rebalance a portfolio, Odos lets you swap [USDC + WETH + ARB] → [ETH + USDT] in a single transaction, saving gas and getting better rates through its Smart Order Router (SOR) that evaluates 1000+ routing paths.
How to Use Odos
- Step 1: Single Token SwapsLike any DEX aggregator — enter a token pair and Odos routes across all DEXes on the selected chain for the best rate.
- Step 2: Multi-Input SwapsThe killer feature: input up to 6 tokens simultaneously in one transaction. Ideal for portfolio rebalancing without chaining swaps.
- Step 3: Smart Order RouterOdos evaluates 1000+ possible routing combinations simultaneously using integer linear programming, maximizing output.
- Step 4: Referral SystemIntegrate Odos into your dApp via the Odos API and earn a referral fee from positive slippage on every swap you route.
Risks to Consider
- Newer protocol — less battle-tested than 1inch
- Smart contract risk from novel multi-path routing
- Token not launched yet (as of 2026)
- MEV risk on large swaps
