# Introduction

## Overview

Hadron is a PropAMM primitive built for professional market makers to provide institutional grade liquidity on Solana. Hadron allows operators to initialize any quoting logic and stores an **explicit updatable pricing curve**, controlling spread and inventory aware pricing. Hadron also gives operators explicit tools to monitor and react to toxic flow.

## Why Hadron?

Access to market making on PropAMMs is severely gated today; makers must navigate the nuances of the SVM, secure landing services, endure slow aggregator integrations, and commit months of engineering effort and audit capital just to get started. Existing PropAMM teams are constrained by trading edge and bandwidth to cover multiple asset types.

New makers with expertise in other assets (RWAs, long-tails, prediction markets, etc.) are bottlenecked by time to market and access to aggregators to even get started. Hadron fixes this.
