Private items are are items that are not visible via Syscoin’s public market search function. Private items can still be located by their identifier, and are visible from the listing functions on the Syscoin wallet that owns the listings, but cannot otherwise be seen from the outside via the wallet.
To purchase a private item navigate to the “Marketplace > Buy” tab/subtab and enter the offer id of the private offer you wish to purchase. This identifier should be provided by the merchant.
Click “Lookup Offer” and as long as enough quantity remain, you’re free to purchase using the normal purchase flow.
