Auction Rules

These rules define how bids are handled, when a sale is binding, and what enforcement actions may apply.

Bid Binding Status

Bids and accepted commercial actions are treated as binding purchase intent, subject to platform acceptance checks, invoicing, payment compliance, and fraud/risk controls.

Auction Duration and Extensions

Standard auction duration is typically 3 days. Soft-close anti-sniping may apply: valid late bids can extend closing by 120 seconds, up to a configured cap.

Reserve and Unsold Outcomes

If reserve is met/exceeded, the winner is invoiced. If reserve is not met, internal decision routes may include underwriter acceptance, release to Buy It Now, Make Offer flow, or relist strategy.

Withdrawals and Anti-shill Rules

Bid manipulation, collusion, shill bidding, and attempts to bypass marketplace controls are prohibited and may trigger account restriction, suspension, or termination.
