# Cartridge

> High Performance Infrastructure for Decentralized Gaming

Cartridge provides tools for building, deploying, and scaling on-chain games on Starknet blockchain with seamless player onboarding.

Cartridge delivers infrastructure for blockchain gaming with three main products: Dojo for game development, Controller for player onboarding and authentication, and Slot for scaling game performance. The platform enables developers to create fully on-chain games with high performance, low latency, and affordable computation while supporting features like Passkeys, Session Tokens, and execution sharding.

## Products

- [Cartridge Slot](https://thegrid.id/profiles/Cartridge): Cartridge Slot provides horizontally scalable execution sharding for blockchain gaming, delivering low-latency contexts with fixed computational costs. The system processes game-specific transactions independently while maintaining provability and settlement with the parent blockchain. (Blockchain Gaming Infrastructure, Live, Main Product)
- [Cartridge Controller](https://thegrid.id/profiles/Cartridge): Controller is a self-custodial embedded wallet for Starknet, enabling secure account provisioning through Passkeys and gameplay optimization with session keys. The system maintains secure signing mechanisms while abstracting blockchain complexities from players. (Embedded Wallet, Live)
- [Cartridge Arcade](https://thegrid.id/profiles/Cartridge): Cartridge Arcade is a permissionless game registration and publishing platform with NFT-based ownership mechanisms, enabling developers to register games, create editions, and manage distribution with integrated discovery features. (Blockchain Gaming Infrastructure, Live)
- [Cartridge VRF](https://thegrid.id/profiles/Cartridge): Cartridge VRF provides atomic, verifiable randomness through cryptographic proofs for onchain games on Starknet. The system processes VRF requests and responses within single transactions using Stark curve verification and Poseidon hashing, enabling synchronous random value generation without multi-transaction delays. (Developer Tooling, Live)
