Overview

This smart contract package allows users to:

• Create and mint NFTs
• Transfer NFT ownership
• Create auctions for NFTs
• Place bids on auctions
• End auctions and transfer NFTs to winners
• Automatically return NFTs to sellers if no bids are placed

The contract is written in the Move language for the Sui blockchain, ensuring secure and efficient operations.

Project Structure

The project consists of three main modules:

1. nft.move: Handles NFT creation, minting, and transfers.
2. auction.move: Manages the auction process, including creation, bidding, and completion.
3. auction_tests.move: Contains comprehensive tests for both the NFT and auction functionalities.

Prerequisites

Before you begin, ensure you have the following installed:

• Sui CLI
• Move language
• Git

Installation

1. Clone the repository:

git clone https://github.com/PGOpenda/nft_auction.git

cd nft-auction-sui

2. Build the project:

sui move build

Usage

Creating an NFT

To create an NFT, use the mint function in the nft module:

nft::mint(name, description, image_url)

One can also transfer the NFT to another if they wished with transfer_nft function in the same module:

nft::transfer_nft(nft,recipient)

Creating an Auction

To start an auction for an NFT, use the create_auction function in the auction module. The duration is in milliseconds:

auction::create_auction(nft, min_bid, duration, clock)

Placing a Bid

To place a bid on an auction, use the place_bid function in the auction module:

auction::place_bid(auction, clock, amount, ctx)

Ending an Auction

To end an auction, use the end_auction function in the auction module:

auction::end_auction(auction, clock, ctx)

Claiming an NFT

The winner can claim their NFT using the claim_nft function in the auction module:

auction::claim_nft(auction, ctx)

Deployment

To deploy the package to the Sui network, we use the following commands in a command line interface:

• Build the package:

  sui move build
  

• Deploy the package:

  sui client publish --gas-budget 10000000
  

• Note the package ID from the output. You'll need this to interact with the deployed contract.
• You can also use Suiscan which provides an interface to interact with the package once deployed.

Testing

Run the tests using the following commands in your commad line interface:

sui move test

This will execute all tests in the nft_auction_tests module, ensuring the correct functionality of both the NFT and auction features.
