# MasterDeployer

A contract that distributes the Concentrated Liquidity Pool, which manages the permission of the factory that creates the pool.

## Overview

![](https://1563666604-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FExVtY885R6zefiJOQZzR%2Fuploads%2FiVxTW9eeB7DFg4UoKjkF%2Fimage.png?alt=media\&token=e9649bd4-ebd4-4b9d-b56e-0ac25e8b5e07)

Pangea adopted the design that separates the factory that creates the pool and the deployer that distributes the pool, as suggested by the Trident. By doing so, specification changes of the pool in the future became more flexible. And furthermore, implementing a customized pool according to the requirements of other DAPPs is made possible.

For example, rebasing tokens such as Ampleforth, whose total supply changes over time, were difficult to be accommodated with the existing pool spec. However, in Pangea, which separates the deployer and the factory, custom pools for such tokens can be developed and distributed according to the request of the protocol.
