Introduction
This project is a smart contract for an auction system implemented in Solidity. The contract allows users to create auctions with a starting price, discount rate, item description, and duration. Bidders can participate in the auction by sending bids, and the contract ensures that the highest bid wins when the auction ends.
Implementation
Features and Functionality
- Create Auction: Allows users to create an auction with a specified starting price, discount rate, item description, and duration.
- Get Current Price: Calculates the current price of the auctioned item based on the time elapsed and the discount rate.
- Buy Item: Allows users to buy the auctioned item by sending the required amount of Ether. The auction ends once the item is bought.
Tests
The project includes a comprehensive test suite written in TypeScript using the Hardhat framework and the Chai assertion library.
