This is a decentralized NFT marketplace built using Solidity, Hardhat, Next.js, and Graph for listening to API calls.
The NFT marketplace allows users to buy and sell non-fungible tokens (NFTs) using Ethereum. Users can connect their Ethereum wallet to the marketplace, view a list of available NFTs, and purchase them using ETH.
The marketplace also allows users to create their own NFTs by uploading NFT Address, setting a price, and listing the NFT for sale.
##Technologies Used 1.Solidity: The programming language used for writing smart contracts on Ethereum. 2.Hardhat: An Ethereum development environment that helps developers write, test, and deploy smart contracts. 3.Next.js: A React framework for building server-side rendered web applications. 4.Graph: A platform for building and querying decentralized APIs.
I have Used Sepolia network You can use your own network and can change in Contracts - Hardhat/helper-hardhat.
In it's own terminal / command line, run:
git clone https://github.com/Vswaroop04/SoliGraph-NFT-Marketplace/
cd SoliGraph-NFT-Marketplace
yarn
cd Contracts - Hardhat
yarn
cd Thegraphbackend
yarn
After installing dependencies, deploy your contracts to sepolia:
cd Contracts - Hardhat
yarn hardhat deploy --network sepolia
You can go to Subgraph and can create a new subgraph and give the link of it in .env of root before that
cd ..
cd Thegraphbackend
graph init --studio <Subgraphname>
graph auth --studio
graph codegen && graph build
graph deploy --studio <Subgraphname>
Then, make a .env file and place your temporary query URL into it as NEXT_PUBLIC_SUBGRAPH_URL.
Make sure that:
- In your
networkMapping.jsonyou have an entry forNftMarketplaceon the sepolia network. - You have a
NEXT_PUBLIC_SUBGRAPH_URLin your.envfile.
