TicketChain

TicketChain is an NFT event ticketing system that allows event organizers to create events and customers to purchase tickets, all on the Ethereum blockchain. This was originally built for UNSW's Software Architecture for Blockchain-based Applications, but it has since been expanded. The hosted web application on the Ethereum Sepolia Test Network can be viewed here.

Installation and Dependencies

Quick start

The first things you need to do are cloning this repository and installing its dependencies:

git clone https://github.com/mgysel/nft-ticketing.git
cd hardhat-boilerplate
npm install

Once installed, let's run Hardhat's testing network:

npx hardhat node

Then, on a new terminal, go to the repository's root folder and run this to deploy your contract:

npx hardhat run scripts/deploy.js --network localhost

Finally, we can run the frontend with:

cd frontend
npm install
npm start

Open http://localhost:3000/ to see your Dapp. You will need to have Metamask installed and listening to localhost 8545.

What's Included?

This repository uses our recommended hardhat setup, by using our @nomicfoundation/hardhat-toolbox. When you use this plugin, you'll be able to:

• Deploy and interact with your contracts using ethers.js and the hardhat-ethers plugin.
• Test your contracts with Mocha, Chai and our own Hardhat Chai Matchers plugin.
• Interact with Hardhat Network with our Hardhat Network Helpers.
• Verify the source code of your contracts with the hardhat-etherscan plugin.
• Get metrics on the gas used by your contracts with the hardhat-gas-reporter plugin.
• Measure your tests coverage with solidity-coverage.

This project also includes a sample frontend/Dapp, which uses Create React App.

Troubleshooting

• Invalid nonce errors: if you are seeing this error on the npx hardhat node console, try resetting your Metamask account. This will reset the account's transaction history and also the nonce. Open Metamask, click on your account followed by Settings > Advanced > Clear activity tab data.
