A system and method for media content management include creating, via a digital vault, a container file comprising media content submitted by a user and content metadata; verifying, via the digital vault, a completeness of the content metadata associated with the media content in the container file; classifying, via the digital vault, the container file based on the completeness of the media content; identifying a salable content item that is to be put up for sale; creating, via the digital vault, a nonfungible token (NFT) container file and populating the NFT container file with the salable content item and NFT metadata; offering the specified ownership rights to the salable content item for sale via an NFT transaction; and updating the NFT container file to reflect a new owner of the ownership rights to the salable content after sale of the salable content item.
