  • **Bidding:** Participants can place bids on ongoing auctions. The highest bidder at the end of the auction wins.
  • **Claiming the Item:** The highest bidder can claim the auctioned item after the auction ends.
  • **Transparency:** All auction details, bids, and winners are recorded on the blockchain, ensuring transparency and immutability.

    <li>**Create an Auction:** Call the 'createAuction' function, providing the item details, starting price, and auction duration.</li> <li>**Place a Bid:** Call the 'bid' function with the auction ID and your bid amount.</li> <li>**Claim the Item:** After the auction ends, call the 'claimItem' function to receive the auctioned item if you are the highest bidder.</li>

    Implementation Details
