Once you have minted / collected a piece on Foundation, you have the ability to create a Private Sale with a collector of your choice. Only one Private Sale can be created per NFT in a 24-hour period. If the NFT is listed, you must un-list it to create a private sale.
Once you are ready to create a Private Sale please follow these steps:
Open the menu on the NFT that you would like to make a Private Sale for
Click on "Create Private Sale"
You will be directed to the Private Sale set up page where you can
Set your price
Search for the collector that you would like to offer the NFT to or paste in the public key
Add a personal message to the collector
Confirm the details of your private sale, once these are set you cannot make any changes until the 24-hour countdown has expired
Sign the message from your wallet, this does not cost any gas
Copy and paste the unique private link and send it to the collector
As soon as this link is created, a 24-hour countdown begins, and the link will expire after this time
Once the Private Sale is created you will not be able to make any changes, the link will expire after 24 hours
