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
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 requires 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 it's ownership is transferred to the new owner.
First of all, it is required to install Metamask wallet browser extension: https://metamask.io/
Then you should configure Metamask to connect to your local blockchain. To do it manually:
- Open Metamask.
- Open the Network Configuration panel.
- Open Custom RPC.
- Connect to Mumbai Testnet.
Another way to connect to Mumbai Testnet is by using the following link: https://chainlist.org/ and add the network of your choice by simply connecting your wallet.
You can get up to 2 MATIC/day by pasting your address here: https://mumbaifaucet.com/.
These instructions will get you a copy of the project up and running on your local machine for development and testing purposes.
First, you will need to clone or fork the repository into your Github account:
git clone https://github.com/assassin1104/JorgePoly.git
First, you will need to install the dependencies.
Run the following command in your terminal after cloning the main repo:
npm install
Then, you will need to install hardhat globally by running the following command into your terminal:
npm install -g hardhat
First, you will have to set up a local network by running the following command:
npx hardhat node
Afterwards, compile the smart contracts by running the following command in your terminal:
npx hardhat compile
Below you can view the smart contract functions (and it's interactions).
Deploy the contracts on your hardhat local network by running the following command:
npx hardhat run scripts/deploy.js --network hardhat
Paste the deployed address in the constants.js file.
Remove the argument provided in the JsonRpcProvider which is located in the line 111 of the NFTContext.js file.
Finally, run the following command in your terminal to open the User Interface:
npm run dev
An instance of Polyplace will be up and running on your local environment.
