# Starknet Wallet Skill

Manage Starknet wallets for AI agents with native Account Abstraction support.

## When to Use

- Creating, funding, and operating Starknet accounts for agent workflows.
- Checking balances, sending transfers, managing session keys, or invoking contracts from an agent wallet.

## When NOT to Use

- DeFi-specific routing, staking, or lending flows better covered by `starknet-defi`.
- Cairo contract authoring, deployment-only operations, or security auditing.

## Quick Start

1. Install the SDK dependencies and set Starknet RPC/account environment variables.
2. Use [skills catalog](../README.md) to pivot to adjacent modules like DeFi, deployment, or auditing.

## Prerequisites

```bash
npm install starknet@^8.9.1 @avnu/avnu-sdk@^4.0.1
```

Environment variables:
