Cartridge
Cartridge is an onchain gaming infrastructure company building the tools and platform that let studios ship fully onchain games and autonomous worlds. It leads development of Dojo, an open-source engine and toolchain for provable games on Starknet, and pairs it with the Cartridge Controller (a game-native smart contract wallet using passkeys, session keys and a paymaster) and Slot, a rollup-as-a-service execution layer. The goal is to give players real ownership of in-game economies while keeping onboarding as smooth as a traditional game.
