It'll be a place where anyone on the internet can learn a little about who you are and send you a 👋 + a message and have that data saved on the blockchain through an Ethereum smart contract.\n\nIt was developed following the steps in [buildspace.so](https://buildspace.so/).\n\n\n![sample image app](./images/app.png)\n\n## Live demo\n\nhttps://waveportal-starter-project.dappsar.repl.co\n\n\n## Technology Stack \u0026 Tools\n\n- Visual Studio Code\n- nvm / nodejs / npm / npx\n- Javascript (React \u0026 Testing)\n- Solidity (Writing Smart Contracts \u0026 Tests)\n- [Hardhat](https://hardhat.org/) (Development Framework)\n- [Ethers.js](https://docs.ethers.io/v5/) (Blockchain Interaction)\n- [React.js](https://reactjs.org/) (Frontend Framework)\n- [Metamask](https://metamask.io/)\n- QuickNode\n- Replit: It is a browser-based IDE that lets us easily build web apps and deploy them all from the browser. It is super legit. Instead of having to set up a full local environment and write commands to deploy, it's all just given to us.\n\n## Requirements For Initial Setup\n\n- Install [NodeJS](https://nodejs.org/en/). Recommended: Use [nvm](https://github.com/nvm-sh/nvm))\n- Register an account and Ethereum Test node in [quicknode](https://www.quicknode.com/)\n- Set un .env file in root folder with this content:\n    * STAGING_QUICKNODE_KEY=(your quicknode url) \n    * PROD_QUICKNODE_KEY=(nothing)\n    * PRIVATE_KEY=(your metamask' acoount private key)\n\n\n## Setting Up\n### 1. Clone/Download the Repository\n`$ git clone repo_url`\n\n### 2. Install Dependencies\n`$ npm install`\n\n### 3. Run tests\n`$ npx hardhat test`\n`$REPORT_GAS=true npx hardhat test`\n\n### 4. Start Hardhat node\n`$ npx hardhat node`\n\n### 5. Run deployment script\nIn a separate terminal execute:\n`$ npx hardhat run ./scripts/deploy.js --network localhost`\n\n### 6. Start frontend\n`$ npm run start`\n\n### 7. Simple run (command line)\n`$ npx hardhat run ./scripts/run.js` \n\n## Links\n\n* [Smart Contract deployed in Goerli Test Blockchain](https://goerli.etherscan.io/address/0x7D2dAeb5DddbD49CB88B0679B8D190bb5561c3dd)\n* [NFT earned after finishing project in buildspace.so](https://opensea.io/assets/matic/0x5c4E5ae2ADEAD056fD39badCe6A5A0e4ceBec3Ee/5)\n\n\n\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fdappsar%2Fbuildspace-projects-simple-dapp","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fdappsar%2Fbuildspace-projects-simple-dapp","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fdappsar%2Fbuildspace-projects-simple-dapp/lists"}
