Prequisites to building a marketplace in Unity

This tutorial series covers the more advanced topics of building a marketplace in Unity on Immutable zkEVM.

There are several prerequisites you need to be familiar with before you can start building a marketplace in Unity.

💡Advanced Tutorial

If you're not familiar with the basic concepts such as authenticating players, connecting their wallets and using NFTs in your game, we recommend you start with the Build a Game in Unity tutorial before attempting to build a marketplace.

This tutorial series assumes you already know how to develop games with Unity, including creating and managing scenes, working with game objects, and basic scripting in C#.

You should already be familiar with the Immutable Unity SDK. If you're you haven't used our SDK before you can find more information in the Unity SDK documentation including the Unity SDK Reference.

You will also need to have a game registered in the Immutable Hub. If you haven't already done this, you can find the steps in the Build a game with Unity tutorial.

Prerequisites

Prerequisite	Description
Unity Version	Unity 2021.3.26f1 is the version used to build the sample game.
Active Unity License	A free personal license can be used.
Immutable Hub Account	An account on Immutable Hub is required to manage projects, create a Passport client, register your game and deploy your NFT collections.
Registered Project	A project registered in the Immutable Hub for your sample game if you haven't already.
