Simple lottery smart contract created with truffle suite

Lottery Smart Contract

A Lottery based game that allows players to create and participate in prize pools

This project is to demonstrate the basic functions of solidity smart contract and how to interact with them in the frontend using web3.js.

How to use

1. Clone the project

   git clone https://github.com/francochau/lottery-smart-contract

   cd lottery-smart-contract

2. Install truffle

   npm install -g truffle

3. Run the development console. truffle develop

   When you load Truffle Develop, you will see the following:

   Truffle Develop started at http://localhost:9545/
   
   Accounts:
   (0) 0x627306090abab3a6e1400e9345bc60c78a8bef57
   ...
   
   Private Keys:
   (0) c87509a1c067bbde78beb793e6fa76530b6382a4c0241e5e4a9ec0a0f44dc0d3
   ...
   
   Mnemonic: candy maple cake sugar pudding cream honey rich smooth crumble sweet treat
   

   You can add one of the accounts to your web3 wallet to interact with the application

4. Compile and migrate the smart contracts. Note inside the development console we don't preface commands with truffle.

   compile migrate

5. In the client directory, we run the React app. Smart contract changes must be manually recompiled and migrated.

   // in another terminal (i.e. not in the truffle develop prompt) cd client

   npm install npm run start

6. To build the application for production, use the build script. A production build will be in the client/build folder.

   // ensure you are inside the client directory when running this npm run build
