How bidding works
- Fund your escrow
Deposit USDC before you bid. While your bid leads a lot, the amount you bid plus the auction house fee is backed by escrow; being outbid releases the collateral, and winning settles it against your invoice.
- Bid
Enter the exact hammer amount you are offering. Bids are binding.
- Successful bid
Yours at the hammer price plus the auction house fee. Invoice at close.
- Settle
Where your collateral covers the invoice, the sale settles the moment the lot closes. A leveraged win leaves a remainder, payable within 48 hours. Miss it and the sale is reversed and a default fee is taken from the collateral you posted — a step anyone can trigger, and one nothing on chain undoes: Conditions of Sale §5. Shipping follows settlement.
You deposit USDC directly into escrow. What the contract can and cannot do with that deposit is set out in how the bid escrow works, and proved against the deployed source in guarantees and limits.

Bidding rules
Enter one flat hammer amount at or above the next minimum. If accepted, that is the amount you bid and the price you can pay; the auction house fee is shown before you confirm. Minthouse does not accept new maximum or proxy bids.
Lots close independently. A bid in the final five minutes resets that lot to five minutes remaining, up to 30 minutes of extensions.
Most lots have no reserve. Premier lots may carry a confidential reserve at or below the low estimate. Below reserve passes; no bids is unsold.
The complete rules for increments, extensions, and settlement windows live in the Conditions of Sale.
