An open decentralized NFT Marketplace built with Solidity and Next.js, powered by Polygon Technologies. It basically is an open platform where users can mint and trade their own NFTs.

An open platform where users can mint their own NFTs and list them on a Marketplace or buy NFT from others. It includes:

A smart contract which represents a collection of NFTs by following the ERC-721 standard.

A smart contract which represents the NFT Marketplace and contains all the logic to make offers, execute offers...

A Next.js front-end application as a user interface.

NFTMarketplace Polygon(Mumbai Testnet) smart contract address:

https://mumbai.polygonscan.com/address/0xF5f6B924332C350E3Fcd3A50Fc94db822f0B760f

https://www.youtube.com/watch?v=kVIb7MGJ53k&t=36s

Users can access the application via web-browser, and must have the Metamask wallet installed. The interface, built with Next.js, relies on the ethers.js library to communicate with the smart contracts through Metamask. This means that the data reflected on the front-end application is fetched from the Polygon blockchain. Each action performed by the user (mint an NFT, sell NFT, buy NFT...) creates a transaction on Polygon, which will require Metamask confirmation and a small fee, and this transaction will permanently modify the state of the NFTMarketplace smart contracts. On top of it, user's NFT Metadata will be uploaded to the IPFS, generating a hash which will be permanently recorded on the blockchain to prove ownership.

Users can perform the following actions on the NFT Marketplace:

Input a name, description and upload a file (image) to mint an NFT. Once minted, a representation of this NFT will be displayed in the marketplace and it will be owned by its creator. This is open for everyone, meaning everyone can participate in this NFT creation through this platform.

A user can buy NFTs which someone else offered. This will require paying the requested price and a small fee.

Users can sell their NFT by specifying its price (in MATIC). If someone fulfills this offer, then the NFT and its ownership is transferred to the new owner.

Below you can view the current's smart contract functions (and its interactions).

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes.

First, it is required to install Metamask wallet browser extension: 

Next, you need to configure Metamask to connect to the desired blockchain by using the following link: 

 and add the network of your choice (Mumbai Testnet for now), by simply connecting your wallet from a test address.

You can get up to 2 test MATIC / day by pasting your address here: 

First, you will need to clone or fork the repository into your Github account:

git clone https://github.com/chrisstef/polyplace.git

Run the following command in your terminal after cloning the main repo:

At this point you will be able to run the frontend with:

Make sure to go through the official Docs: 

https://hardhat.org/hardhat-runner/docs/getting-started#overview

Initialize hardhat by running the following command:

First, you will have to set up a local network by running the following command:

After you are happy with your changes in NFTMarketplace.sol file, compile the smart contract:

Deploy the contracts on your local hardhat network by running the following command:

npx hardhat run scripts/deploy.js --network localhost

If all goes well, a new smart contract address refering the NFT Marketplace will be generated. Paste this address in the constants.js file.

Next, remove the argument provided in the JsonRpcProvider which is located in the 

Finally, run the frontend on a new terminal to open the User Interface:

A local instance of Polyplace will be up and running on your local environment.

 for a more in depth way how to contribute.

We recommend Vercel to deploy this app, after you made your changes on the app.json config file, just use the button below:

Note that you need to set up INFURA_API_KEY to Next js be able to generate pages.

NEXT JS + Material UI+ Typescript + Boilerplat

Additionally we use trader sdk to handle nft smart contract interactions, react query to handle all http and blockchain requests, format js for internalization, web3 react to handle wallet logic. You can check our requirements 

We will be adding any new evm network that 0x smart contracts will support.

It is also planned to extract all common hooks and state used to interact with the blockchain to a library repo.

If you need a zero code solution we are building one currently in beta at 

 as well about it. Instead, if you want to deploy your own custom solution using this repo, please fork it, update the app.json file accordingly on the config folder and then deploy on Vercel (Recommended) or Heroku.

We welcome missing features, but take in mind that this repo is intended to be a base app for any dev to start working on, if it makes sense to have that feature on this base app we will include, if it is considered a premium feature, we will be including on our premium marketplace which uses this one as a base.

We at the moment consider premium features as follows:

- Fetch NFT and token balances via api without the need to import, using Alchemy for instance

- Collection level stats like orders, max supply, floor price, number of trades

We would like to thank ZRX project for these amazing tools and ZRX DAO for the support on building this open source app.

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 

You can use third-party login providers like GitHub or Google. Refer to the

To start developing your SaaS application, we'll need to configure Stripe to handle test payments. For the following steps, make sure you have the 

We need to configure the webhook pictured in the architecture diagram above. This webhook is the piece that connects Stripe to your Vercel Serverless Functions.

Set the endpoint URL to https://your-deployment-url.vercel.app/api/webhooks.

Click Select events under the Select events to listen to heading.

Click Select all events in the Select events to send section.

Copy Signing secret as we'll need that in the next step.

To securely interact with Stripe, we need to add a few 

 in Stripe. The STRIPE_WEBHOOK_SECRET_LIVE is the Signing secret copied in the previous webhook configuration step.

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 

 to bootstrap test product and pricing data in your Stripe account. Simply run stripe fixtures fixtures/stripe-fixtures.json.

 Be sure to start the webhook forwarding (see below) so that the products created by the fixtures command above are imported into your database.

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.
