Listing an Item

For S&box, open Sell S&box items to load your Steam inventory. You can compare current asking prices in the S&box Marketplace before setting your listing price.

• Navigate to your inventory page and click the List Item button.

• Choose from three listing types:

  • Buy Now – Buyers send purchase requests at the full listed price.
  • Negotiable – Buyers can offer up to 50% below the listed price.
  • Auction – Set a minimum starting bid and auction duration (see auctions guide for details).

• Enter the listing price and click List Item. Your item will now be available for purchase.

Handling Requests

• When a buyer purchases your item or submits a negotiable offer, you can accept or decline it on the Trades page.
• Once accepted, Dupe’s peer-to-peer verification process begins to safely fulfill the trade.

The Dupe Mobile App

To ensure the highest grade of security, the Dupe Mobile App is required to fulfill the trade to the buyer.

The Dupe mobile app is available on the Apple App store and the Google Play Store.

Completing the Sale

• After the buyer accepts your Steam trade offer, Dupe verifies the trade and sends USDC to your wallet.

Happy trading!
