A non-fungible token is a processed data (token) unit maintained on a blockchain that is not interchangeable with other digital assets for the purposes of this definition (nonfungible). The term "fungible" is derived from economic and accounting literature and refers to anything that may be replaced with a comparable or identical commodity.

Full stack A NFT marketplace built with Polygon, Solidity, IPFS, & Next.js

Running this project

Local setup

To run this project locally, follow these steps.

1. Clone the project locally, change into the directory, and install the dependencies:

git clone https://github.com/mazhar11-cou/DigitalStack-A-NFT-Marketplace.git

cd DigitalStack-A-NFT-Marketplace

# install using NPM or Yarn
npm install

# or

yarn

2. Start the local Hardhat node

npx hardhat node

# or

yarn hardhat node

3. With the network running, deploy the contracts to the local network in a separate terminal window

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

# or 

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

4. Start the app

npm run dev

# or

yarn dev

Configuration

To deploy to Polygon test or main networks, update the configurations located in hardhat.config.js to use a private key and, optionally, deploy to a private RPC like Infura.
