# Lottery Smart Contract
This is a simple Ethereum lottery smart contract built using Solidity. Participants can enter the lottery by sending a specified amount of Ether to the contract. Once enough participants have entered, the contract owner (manager) can choose a random winner who will receive the entire pool of Ether.

## Prerequisites
- Node.js v10 or later
- npm or yarn
- Truffle
- Ganache
## Getting Started
1. Install Truffle globally:
```bash
npm install -g truffle
```
2. Clone the repository and navigate to the project directory:
```bash
git clone https://github.com/yourusername/lottery-smart-contract.git
cd lottery-smart-contract
```
3. Install the required dependencies:
```bash
npm install
```
4. Run Ganache to start a local Ethereum network:
```bash
ganache-cli
```
5. Compile the smart contracts:
```bash
truffle compile
```
6. Deploy the smart contracts:
```bash
truffle migrate
```
## Testing
Run the test suite by executing:
```bash
truffle test
```
## Deploying to a live network
To deploy the smart contract to a live network, update the `deploy.js` file with the appropriate configuration for your target network. For example, to deploy to the Ropsten test network:
```javascript
const HDWalletProvider = require('@truffle/hdwallet-provider');
const { mnemonic, infuraKey } = require('./secrets.json');
module.exports = {
networks: {
ropsten: {
provider: () => new HDWalletProvider(mnemonic, `https://ropsten.infura.io/v3/${infuraKey}`),
network_id: 3,
gas: 5500000,
},
},
};
```
You will need to create a `secrets.json` file in the project root directory containing your mnemonic and Infura key:
```json
{
"mnemonic": "YOUR_MNEMONIC_HERE",
"infuraKey": "YOUR_INFURA_KEY_HERE"
}
```
After updating the configuration, run the following command to deploy to the live network:
```bash
truffle migrate --network ropsten
```
