With this in mind, NFTs are unique; each one is different. Every single token has unique characteristics and values. They are all distinguishable from one another and are not interchangeable eg Unique Art\n  ![NFT's Creation Process](https://i.imgur.com/wt4qWKT.jpg)\n\n- What is ERC-721?\n  ERC-721 is an open standard that describes how to build Non-Fungible tokens on EVM (Ethereum Virtual Machine) compatible blockchains; it is a standard interface for Non-Fungible tokens; it has a set of rules that make it easy to work with NFTs. Before moving ahead have a look at all the functions supported by [ERC721](https://docs.openzeppelin.com/contracts/3.x/api/token/erc721)\n\n## Technology Stack \u0026 Tools\n\n- Solidity (Writing Smart Contract)\n- Javascript (React \u0026 Testing)\n- [Web3](https://web3js.readthedocs.io/en/v1.5.2/) (Blockchain Interaction)\n- [Truffle](https://www.trufflesuite.com/docs/truffle/overview) (Development Framework)\n- [Ganache](https://www.trufflesuite.com/ganache) (For Local Blockchain) for testing purpose\n- Goerli Testnet for deployment\n- [MetaMask](https://metamask.io/) (Ethereum Wallet)\n- [ThreeJS](https://threejs.org/docs/index.html) (3D Javascript library)\n- [@react-three/fiber](https://docs.pmnd.rs/react-three-fiber/getting-started/introduction) (React renderer for Three.js)\n- [@react-three/drei](https://docs.pmnd.rs/drei/introduction) (Extra helpers for React-Three-Fiber)\n\n## Requirements For Initial Setup\n\n- Install [NodeJS](https://nodejs.org/en/), I recommend using node version v14 or v16 to avoid any potential dependency issues\n- Install [Truffle](https://www.trufflesuite.com/docs/truffle/overview), In your terminal, you can check to see if you have truffle by running `truffle --version`. To install truffle run `npm i -g truffle`.\n- Install [Ganache](https://www.trufflesuite.com/ganache).\n- Install [MetaMask](https://metamask.io/) in your browser.\n\n## Setting Up\n\n### 1. Clone/Download the Repository\n\n### 2. Install Dependencies:\n\n`$ yarn`\n\n### 3. Migrate Smart Contracts\n\n`$ truffle migrate --reset`\nor\n`$ truffle migrate --reset --network goerli`\n\n### 4. Test Smart Contracts\n\n`$ truffle test`\n\n### 5. Start Frontend\n\n`$ yarn start`\n\n## Requirements For Running App\n\n#### 1. Setup a local blockchain network for running Ganache-Cli with these credential or as per your choice:\n\n- Network name: \"Local Network CLI\"\n- New RPC URL: \"http://127.0.0.1:8545/\"\n- Chain ID: \"31337\"\n- Currency symbol: \"ETH\"\n- Block explorer URL(OPtional): fill it\n  or leave it empty as per your choice\n\n#### 2. Run the Local blockchain in one terminal and keep it running by writing also copy and import first two accounts' private into your metamask wallet using :-\n\n`$ npx ganache-cli`\n\n#### 3. Now start the App using new terminal and purchase the plot of land using:-\n\n`$ yarn start`\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fhellosumitg%2Fmeta-city","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fhellosumitg%2Fmeta-city","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fhellosumitg%2Fmeta-city/lists"}
