# Contracts

The ukiyo ecosystem utilizes a broad tech stack and several in-house and third-party smart contracts to provide services to its users.

Primarily, the smart contracts are used to facilitate:

* Collecting users' initial contributions to Ventures
* Chainlink CCIP
* RestAPI
* Funding investments;
* Capturing and creating Intellectual Property
* Distributing proceeds; and
* Rage quitting

Below you can find early examples of **deprecated** contracts that were built and tested.
