ETH-BET tournament betting

Description

Users can bet on various tournaments for different professional esports. For the time we have to develop this application and the fact that the API has a monthly cost, it will be limited to a list of 6 tournaments taken from a sample JSON given by the API provider for free for development.

Structure of each tournament

What smart contract can do?

Getting started

Install

1. node.js - https://nodejs.dev/
2. truffle - npm install truffle -g
3. ganache - https://www.trufflesuite.com/ganache
4. run npm install from the project folder to install everything from node_modules folder

Run localy

1. Start ganache/ganache-cli (This is a personal ethereum blockchain)
2. go to projects /contract folder where truffle-config.js file is placed. (Here we set up deployment options)
3. run truffle migrate --network development to deploy a contract to development network
4. copy contract address and replace a variable contractAddress in config.js file in ./eth-bet/src/
5. Go to eth-bet folder and run npm start to start the UI
6. If backend is not properly connected, then an alert would popup in the browser window.

Deploy to infura.io

1. Go to /contract/ folder

3. Wait until got a result simillar to what is on the image below.
