# 1st DEX — Market Maker API

These docs cover how to **quote**, **update**, and **risk‑manage** orders programmatically using:

* The on‑chain **Controller** contract (single entrypoint) to batch trading actions.
* The **Subgraph** to read books, orders, and fills with low latency.

> **Architecture:** each *pair* has **two order books**, one per direction. Orders are denominated in **units** (multiples of `unitSize`) at discrete **ticks**. See [Books & units](/mms-api/concepts/books-and-units) and [Ticks](/mms-api/concepts/ticks).

## What's different vs AMM DEXes?

* **Price–time priority** instead of pools and curves.
* **Quote‑collateralized** makers: quote is locked when you `MAKE`, released when you `CANCEL` or after `CLAIM`.
* **Fee model** with protocol fees and optional **referrer** fee sharing.
* **Single batch entrypoint**: all actions go through `Controller.execute(...)` so you can atomically make/take/cancel/claim in one tx.
