# Voting Build your first decentralized application, or dApp, on the Bitcoin with this tutorial. [LIVE DEMO](http://classic.scrypt.io/voting/) 🚀 ## Step 1. Clone the project ```bash $ git clone https://github.com/sCrypt-Inc/voting.git ``` ## Step 2. Install dependencies ```bash $ cd voting $ npm install ``` ## Step 3. Compile contract ```bash $ npx scrypt-cli compile ``` ## Step 4. Add your API Key Use your own API key in file `index.tsx`. If you don't have it, please follow this [guide](https://docs.scrypt.io/advanced/how-to-integrate-scrypt-service#get-your-api-key) to get one. ```ts Scrypt.init({ apiKey: 'YOUR_API_KEY', // <--- network: 'testnet' }) ``` ## Step 5. Deploy contract Before deploying the contract, create a `.env` file and save your private key in the `PRIVATE_KEY` environment variable. ```text PRIVATE_KEY=xxxxx ``` If you don't have a private key, please follow [this guide](https://scrypt.io/docs/how-to-deploy-and-call-a-contract/#setup) to generate one using [Sensilet](https://sensilet.com/) wallet, then fund the private key's address with our [faucet](https://scrypt.io/faucet/). Run the following command to deploy the contract. ```bash $ npm run deploy:contract ``` After success, you will see an output similar to the following:  Copy the deployment TxID then change the value of `ContractId` in file `src/App.tsx`: ```ts const contract_id = { txId: "bccf73c0f49920fdbd2c66972b6ab14ac098239c429176acf5e599acb7dc6d4a", outputIndex: 0, }; ``` ## Step 6. Run the frontend app ```bash $ npm start ``` Runs the app in the development mode. Open [http://localhost:3000](http://localhost:3000) to view it in the browser.
