Sunflower Land

The goal of this project is to create a decentralized and community driven MetaVerse style game.

This repo includes the front-end game which users can play and interact with the game on the Polygon Network and off chain data.

Getting Started

Firstly, you will need to clone the repo locally. Once you have it ready navigate into the directory and run the following commands:

  1. npm install --global yarn (if you don’t have yarn installed)
  2. yarn install
  3. yarn dev


yarn test

This runs a range of business logic unit tests in the repo.

The plan is to use react testing library to test some of the core user interactions as well.


We use xstate to control the manage the user and session using a State Machine approach. This prevents our application from getting into invalid states and handles the use cases of switching accounts, networks, etc.

The primary states include:

  • Connecting (connecting to MetaMask)
  • Ready (Waiting for user input – Start)
  • Signing (Sign a message to verify the account on the API)
  • Authorising (Checking if a user has an account/farm)
  • Unauthorised (when one of the above state transition fails)
  • Authorised (Play the game!)


The app uses vite for bundling and development purposes. You can set build specific configuration in vite.config.ts


Tailwind is our CSS tool of choice. It enables us to:

  • Use utility based classes
  • Consistent theming (view tailwind.config.js)
  • Perform CSS processing to minimize build sizes

Directory Organization

  • Assets: Images, Music, Branding and other Media
  • Components: Reusable react components
  • Lib: Utils, classes, machines and more.
  • Features: Core domain concepts that have their own use cases/boundaries. Each feature (e.g. crops) has a similar nested structure of components, graphql & lib that are specific only to that feature.
