Good news! The UCIF Auction House is on the Mainnet!
To see the auctions, follow these steps:
1) Have TronLink running and go to
https://ucift-auction-house.web.app/2) Click on the My Auctions tab then the Auctions tab
3) Click the listing to Bid or Buyout token
4) Your offers will be listed on the Offers tab
Each transaction is on TronLink smart contracts so it will require a little bit of TRX to cover the transaction costs but there are no additional fees.
