what's cartridge?

Cartridge is an onchain gaming company focused on building infrastructure, tools, and games that enable provable and autonomous worlds on blockchain networks. Founded to address key challenges in blockchain gaming, such as user onboarding and seamless cross-chain interactions, Cartridge develops solutions like the Cartridge Controller, which leverages Account Abstraction on platforms like Starknet to allow users to create secure, passwordless accounts accessible across devices without managing seeds or gas tokens directly. The company emphasizes empowering developers to create fully onchain experiences, from strategy games to tournaments, by integrating features like gasless transactions through partnerships with protocols such as Avnu. Cartridge has backed innovative titles and studios, including collaborations with creators from Magic: The Gathering and Hearthstone, to push the boundaries of blockchain-based gameplay. Through funding rounds, including a $7.5M Series A led by BITKRAFT Ventures, Cartridge continues to expand its ecosystem, supporting onchain RTS games, treasure hunts, and multiplayer battles that reward tactical mastery and automation in a verifiable environment.

Cartridge acquired onchain gaming company Playmint, known for games like The Crypt and Downstream.
