Cavos React SDK — AI Agent Skill

Complete architectural knowledge and implementation patterns for @cavos/react. This skill enables AI agents to correctly integrate, extend, and debug the Cavos SDK.

1. What is Cavos?

Cavos is a non-custodial account abstraction SDK for Starknet. It lets users create smart wallets using their existing OAuth identity (Google, Apple, or passwordless Magic Link) — no seed phrases, no browser extensions.

Key Principles

• Non-custodial: The user's wallet is derived deterministically from their OAuth sub claim + a per-app salt. No one holds the keys.
• Gasless by default: All transactions go through the Cavos paymaster (SNIP-9 Outside Execution).
• Session keys: Ephemeral ECDSA keys that sign transactions on behalf of the user, with configurable spending limits and contract restrictions.
