Software development kits, methods, and systems that facilitate blockchain transactions by game engines and game applications

This invention describes a system that lets video games interact with blockchain technology. When a player performs an action with an item in the game that's linked to a digital token on a blockchain, the game uses a special software kit (SDK) to connect to the player's digital wallet. This connection allows the game to request a secure signature for a blockchain transaction, and once confirmed, the game completes the player's action, such as buying an item with cryptocurrency or trading it with another player.
