This project is a web3 sandbox proof of concept, that allows users to purchase digital worlds in the form of NFTs, build upon them using 3D rendered blocks, and share those worlds inside of a metaverse that is saved to the blockchain.

The block-building gameplay aspect of this project was adapted from 

The proof of concept utilizes an in-game cryptocurrency, called MBlox, which faciliates the purchasing of different digital blocks for users to build with and the worlds in which they build.

The project is also playable without any web3 knowledge or integration; there is a "Sandbox" mode available from the Main Menu which allows a user to build within a provided digital world with an infinite number of blocks without the need of any web3 wallet connection or crypto balance of any kind.

This project was also deployed using Vercel (referenced in the stack above), and is available to play at the following address: 

NOTE: This project is a proof of concept, and not intended to represent a polished Web3 application. The contract system used in this application has not been audited, and I take no responsiblity for any issues that may arise out of its extended use.

There are four main aspects of gameplay within the project. These are as follows:

This aspect of gameplay allows users to convert their Polygon Mumbai Matic into the in-game currency (MBlox) to use within the game.

Alternatively, if the user has previously played by 

 and has earned the in-game METR token of that game with the wallet they have connected to this project, they will be able to claim a lump sum of MBlox equal to the difference their last claim and their current claim, (e.g. if they are claiming for the first time, the user can claim their entire METR balance as MBlox, and if they play METARANGERS since then and claim more METR since then, they can claim the new METR they have earned as MBlox)

This area of the project is where players can exchange their MBlox for the MetaBlox token, which represents the different blocks that can be used to build within the worlds of the game

The different variations of blocks that are available to the user are Dirt, Grass, Glass, Wood, Log, Lava, Gold, Opal, Amethyst, and Space.

As described earlier, this aspect of game allows the player to enter a digital world (equivalent to one of the worlds of the game) and build whatever they desire within it with an unlimited number of blocks at their disposal.

Players are unable to save anything that they create within the Sandbox to the blockchain, as this mode is intended to be an avenue of gameplay available to Web2 users.

This aspect of gameplay allows user to either purchase new worlds to build in, build in said purchased worlds, visit other user's individual worlds, or visit the MetaGrid itself, which is a vast digital world in which all one hundred available worlds within the project and rendered and laid out before the user, which they can explore in its entirety.

The different worlds are laid out in a grid of tiles, with coloured tiles represent worlds that are already purchased by users, and black tiles representing unclaimed worlds available for purchase.

This proof of concept uses a smart contract system that includes four implementations and seven interfaces. All the contracts were deployed to the 

, were written in the Solidity programming language and deployed using Hardhat, both of which are referenced in the stack displayed above. The implementations used in this smart contract system are as follows:

This contract represents the in-game currency that is primarily used to purchase the other tokens in the game.

 that provides basic minting and burning functionality.

This contract represents the different blocks that the user is able to purchase and then use to build with within the game.

, that contains balances for each of the variants of blocks as described above, the prices of each block in MBlox, and minting, burning, and batch minting and burning functionality.

This contract represents the different worlds that users can purchase and build within the game.

, that includes URI storage and burning functionality.

This contract facilitates interactions between the game and smart contract system.

 and includes several key aspects of functionality, including getter functions for retrieving values relevant to the game, enabling users to purchase other tokens within the MBlox in-game currency, and handling changes to world tokens that users make by placing and removing blocks.

The Game Manager also restricts the minting and burning capability of the other contracts in the system to actions that occur in the game, to prevent malicious users from attempting to mint or burn tokens outside of the context of the game. This is primarily facilitated through the use of a "digitalKey" variable that is required to call any functions that pertain to major functionality.

Built with Next.js 13, Tailwind CSS + daisyUI, react-chessboard, chess.js, Express.js, socket.io and PostgreSQL.

This project is structured as a monorepo using npm workspaces, separated into three packages:

client - Next.js application for the front-end, deployed to 

server - Node/Express.js application for the back-end, deployed to 

types - Shared type definitions for the client and server.

# install all dependencies, including eslint and prettier for development npm install # concurrently run frontend and backend development servers npm run dev # -w client/server to run only one # for separate production deployments npm install -w client npm install -w server npm run build -w client npm run build -w server npm start -w client npm start -w server

For separate deployments, you may exclude the client or server directory. However, you should include the types folder as it contains shared type definitions that are required by both packages.

You may create a .env file in each package directory to set their environment variables.

Horse Race is a web implementation of a drinking game usually played with a deck of cards. Players bet on up to four horses (represented as aces of a suit) and the horses themselves move across the 'field' based on cards that are drawn from the deck. Technologies used include Chakra UI, Emotion, Next.js, React, and TypeScript.

Input the number of players you would like to play with.

Input their names as well as their corresponding bets. Players can bet on as many horses (suits) as they would like but currently are limited to a single text field for a bet.

Once all of the players have put in their bets, click 'Play'.

That's it! The game plays entirely on its own and its up to you and your friends to cheer on the horses as they make their way across the track!

Once a horse is crowned the winner, a button to see the results will be revealed. Click on 'Results'.

The Summary page will show all of the winning and losing bets. Do what you will with the information 😏

The Vercel deployment will guide you through creating a Supabase account and project. After installing the Supabase integration, you'll need to configure Stripe with a few simple steps.

 We're working on our Stripe integration. We've documented the required steps below under "Configure Stripe" until the integration is ready.

Once the project has deployed, continue with the configuration steps below.

The initial build will fail due to missing Stripe environment variables. After configuring Stripe, redeploy the application.

Setup redirect wildcards for deploy previews

For auth redirects (magic links, OAuth providers) to work correctly in deploy previews, navigate to the auth settings (i.e. https://app.supabase.com/project/:project-id/auth/url-configuration) and add the following wildcard URL to "Redirect URLs": https://**vercel.app/*/*.

You can read more about redirect wildcard patterns in the

We need to redeploy the application so that the latest environment variables are present.

Redeploy your application by going to the deployments tab, finding your deployment, and clicking "redeploy."

For Stripe to automatically bill your users for recurring payments, you need to create your product and pricing information in the 

. When you create or update your product and price information, the changes automatically sync with your Supabase database.

Stripe Checkout currently supports pricing that bills a predefined amount at a specific interval. More complex plans (e.g., different pricing tiers or seats) are not yet supported.

For example, you can create business models with different pricing tiers, e.g.:

 fixtures command executes a series of API requests defined in a JSON file. To speed up the setup, we have added a

Archive all test mode Stripe products before going live. Before creating your live mode products, make sure to follow the steps below to set up your live mode env vars and webhooks.

Configure production environment variables

To run the project in live mode and process payments with Stripe, modify the environment variables from Stripe "test mode" to "production mode." After switching the variables, be sure to redeploy the application.

To verify you are running in production mode, test checking out with the 

Afterward, you will need to rebuild your production deployment for the changes to take effect. Within your project Dashboard, navigate to the "Deployments" tab, select the most recent deployment, click the overflow menu button (next to the "Visit" button) and select "Redeploy."

Deploying with Vercel will create a repository for you, which you can clone to your local machine.

Use the Vercel CLI to download the development env vars:

Running this command will create a new .env.local file in your project folder. For security purposes, you will need to set the SUPABASE_SERVICE_ROLE_KEY manually from your 

 (Settings > API). Lastly, the webhook secret differs for local testing vs. when deployed to Vercel. Follow the instructions below to get the corresponding webhook secret.

stripe listen --forward-to=localhost:3000/api/webhooks

Running this Stripe command will print a webhook secret (such as, whsec_***) to the console. Set STRIPE_WEBHOOK_SECRET to this value in your .env.local file.
