Ultimate Auction System

Ultimate Auction System adds a complete, player-driven auction house to Minecraft. Built for servers that want a deeper economy experience, UAS lets players list items, place bids, use buyout prices, watch auctions, and claim won or returned items through a clean in-game interface.

Players can open the auction house with /ah, browse active listings, search for items or sellers, filter auctions by category, mod, price range, closing time, and sort order, then bid or buy out listings directly from the GUI. Auctions can be created from single item stacks or full bundles, with custom titles, starting bids, optional buyout prices, reserve prices, sealed-bid support, descriptions, end times, and listing fee previews before confirmation.

UAS is powered by Ultimate Banking System, meaning all auction money flows through real UBS accounts. Listing fees, bid escrow, outbid refunds, buyout payments, seller payouts, sales tax, and recovery handling are all connected to the banking system instead of using a separate economy.

The mod also includes a player dashboard where users can track active auctions, ending-soon listings, claimable rewards, watched auctions, and auction history. For server owners, UAS provides admin tools for monitoring auction activity, reviewing players, managing economy flow, moderation, banned items, recovery tools, audit history, fees, rate limits, and more.

Whether you want a simple marketplace or a full server economy hub, Ultimate Auction System gives your players a modern, secure, and feature-rich auction house experience.
