controller-backend

What problem does it solve?

This Skill enables backend systems to programmatically sign and execute Starknet transactions through Cartridge Controller, removing the need for interactive browser approvals and enabling automated game servers, bots, and other non-browser environments.

Core Features & Use Cases

• Node.js SessionProvider: Configure file or cloud-backed session storage to create persistent, pre-authorized sessions for server processes.
• Rust native integration: Use account_sdk and starknet crates to deploy controllers, manage owners, and execute transactions from native Rust applications.
• Headless Controller & custom signers: Run headless controllers with environment-managed private keys for single-owner bots, automated accounts, or HSM-backed signing.
• Telegram Mini-Apps: Integrate SessionConnector flows and proper WebApp redirects for Telegram-based mini-app authentication and transaction execution.
• Use Case: Automate game backends to sign player actions, run NPC bots, or perform scheduled on-chain transfers without human interaction.

Quick Start

Initialize a SessionProvider with a writable basePath, configure RPC and policies, connect the provider, and execute a sample transfer to verify server-side transaction flow.
