Services
Cartridge offers a set of platform services for onchain games and applications:
- Paymaster — sponsor transaction fees so your users don't need to hold STRK for gas.
- RPC — Starknet RPC endpoints for mainnet and Sepolia, with API token and CORS-based authentication.
- vRNG — atomic, verifiable randomness for fully onchain games via EC-VRF on the Stark curve.
Each service is self-served via the CLI and can be used independently or together.
