# Serum Ecosystem **Serum** provides a *fully on-chain* **orderbook**, allowing applications such as trading interfaces to 'plug into' Serum's composable ecosystem. Serum lives in the heart of the ecosystem, providing services to its ecosystem applications, each with their own technology and set of users. Anyone can create a trading application that leverages Serum's liquidity and its ecosystem benefits. To illustrate this concept: an order made on one dApp composing with a Serum orderbook market can be matched with an order made on completely separate dApp composing with that same market! Retail Traders, Developers, and Algorithmic Traders can all connect to Serum and leverage its shared liquidity, or build a marketplace. ![](https://gblobscdn.gitbook.com/assets%2F-MX0KCPgI-ecLKfYa3jX%2F-MjSaXQwyOQ5D_MhzxKD%2F-MjToIDeunhjxkLxPTNk%2FSerum%20Graphic.png?alt=media\&token=0b245839-542a-42eb-a121-0ff1d4aba28f) ### --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
