Bid history
No bids yet.
Local simulation with fictitious bidders. It's not a real auction and creates no payment obligation.
Real countdown
The server keeps the clock. Everyone sees the same close.
Auto-extension
A bid in the last 30 seconds extends the auction.
Verified sellers
Identity confirmed before the first lot is published.
Pay within 24 hours
The winner has a clear window to complete the purchase.
How it works
Sign up as a buyer, seller or both. Sellers go through identity verification.
Search by category, follow the lots you like and bid with clear increments while watching the history in real time.
If someone bids in the last 30 seconds, the clock extends. Nobody wins with a last-instant click.
If you win, you get a confirmation and have 24 hours to pay through the platform's payment provider.
