# Introduction

## What is Dbook?

Dbook is a EVM order book exchange that is fully on-chain and highly gas-optimized.

## Technical Overview

Dbook was built from first principles to tackle the challenges of bringing an order book exchange completely onto the blockchain while meticulously optimizing for gas performance. This was achieved by implementing custom algorithms and data structures to hyper-optimize the Dbook contracts, allowing Dbook to be a scalable EVM primitive.
