Auctions #

Hiro Auctions provides an open marketplace for users to trade items through competitive bidding within a set time frame. The system ensures fair participation by validating a user’s ability to afford bids, and guarantees reliable exchanges between the highest bidder and the seller at the end of each listing.

An auction listing is essentially an item for sale with a series of bids. Key elements include:

• The end time of the listing.
• The current highest bid or starting bid.
• The minimum required bid for the next participant.

Listings can only be created for items in the seller’s Hiro Inventory.

Lifecycle #

Each auction progresses through a simple, linear process:

1. Creating a Listing: The seller chooses an item from their inventory, and it is removed from their possession until the auction concludes.
2. Bidding: Other users bid, with amounts deducted from their wallets to ensure they can afford the bid at both placement and auction close. Users cannot bid on their own listings or on those where they are the current highest bidder. Bidders that were outbid get their currency back immediately, no waiting until the end of the auction.
3. End of Auction: The listing concludes, and both the seller and winning bidder are notified to claim their rewards.
   • The seller collects the bid amount (minus fees).
   • The bidder receives the item.
