The parent company of game engine developer Unity applied for a patent related to game cryptocurrency tokens, according to documents from the United States Patent and Trademark Office revealed on March 5. The Danish parent company is reportedly targeting missing links in the in-game token market.

“There are currently no known ways to assign objects (both physical and virtual) to unique identifiers and allow those objects to be altered, transferred, swapped, exchanged, traded, given, and associated with a location,” the patent’s description reads.

“There is no common platform or standard of understanding on how this could be done across users, applications and environments where the tokens and their associated objects can then be manipulated by applications or users in order to form collections and trigger events based on object transformations.”

Just this week, CoinTelegraph reports that the digital asset tokenization startup Enjin released a “dedicated software development kit (SDK) for Unity.” The software will enable Unity developers to create, integrate and manage the distribution of ERC1155-compliant tokens on the Ethereum (ETH) blockchain. It will also enable interoperability, allowing players to use their virtual items in multiple games.
