# Odos & Orbs

Our primary engine also incorporates the [ORBS](https://www.orbs.com/) Liquidity Hub, an optimization layer designed to access external liquidity sources, enhancing price execution and minimizing price impact. \
\
If the Liquidity Hub cannot provide a better price than the main engine, the trade defaults to the AMM contract and continues seamlessly. \
\
This system aggregates liquidity from both on-chain and off-chain sources to offer highly competitive pricing. The Liquidity Hub achieves this by leveraging a network of solvers, operating both on-chain and off-chain, that compete to secure the most cost-efficient liquidity for traders.

The key benefits of ORBS for SwapX users and LPs include:

* LPs retain the same revenue levels with the Liquidity Hub as they would without it, ensuring no negative impact
* The Liquidity Hub eliminates arbitrage losses to MEV by matching orders without relying on block producers
* The protocol allows DEXs to incorporate a standard centralized CEX book API, enabling traditional market makers to participate in DeFi
* Trades executed via the Liquidity Hub are entirely gasless for users
* The DEX interface and swap flow remain unchanged, ensuring a smooth and familiar process for users
