Cross-chain Auction

Description

The Cross-chain Auction project is a platform for cross-chain auctions. The main idea is to create a single smart contract that allows users to participate in auctions across multiple blockchains.

Features:

• Create auctions via smart contracts.
• Support for interaction across multiple blockchains.
• Automatic bid management and synchronization of data between networks.

Technologies

• Solidity: smart contract implementation.
• Hardhat: toolkit for testing and deploying contracts.
• HTML, CSS, JavaScript (Ethers.js): for the frontend.

Installation

Steps to Install

1. Clone the repository:

   git clone https://github.com/artman325/Auction.git
   cd Auction

2. Install Hardhat dependencies:

   npm install

3. Set up a local HTTP server to serve the HTML files. For example:

   npx http-server .

Usage

Page Structure:

1. produce.html:

   • Form to create an auction. Users can specify parameters such as:
     • Token address (token).
     • Number of winners.
     • Time settings (startTime, endTime).
     • Starting price (startingPrice) and price increment step.

2. produce.js:

   • Script for blockchain interaction. Includes:
     • MetaMask integration.
     • Network switching and contract calls.
     • User interface management.

Auction Workflow:

• After creating an auction via produce.html, the auction data is synchronized across blockchains.
• Users can place bids on any supported blockchain.
• Once the auction ends, winners can claim their NFTs using the corresponding buttons in the interface.

Key Files

• Auction.sol: main auction contract.
• AuctionFactory.sol: factory contract for creating new auctions.
• IAuction.sol, IAuctionFactory.sol: interfaces for the contracts.
• produce.html, produce.js: user interaction interface.
