# Starknet Identity Skill

Register and manage AI agent identities on Starknet using the ERC-8004 standard.

## When to Use

- Registering agents on-chain, updating agent metadata, or managing reputation and validation flows.
- Building features that depend on ERC-8004 identity, feedback, or validator attestations.

## When NOT to Use

- Simple wallet, payment, or DeFi flows that do not depend on ERC-8004 registries.
- Cairo contract authoring, deployment-only tasks, or security auditing.

## Quick Start

1. Install `starknet` and connect a funded account to the target ERC-8004 registry deployment.
2. Use [skills catalog](../README.md) if the flow also needs wallet setup, deployment, or contract auditing.

## Overview

ERC-8004 defines three interconnected on-chain registries for AI agents:

1. **Identity Registry** -- Agents as ERC-721 NFTs with metadata
2. **Reputation Registry** -- Feedback system with cryptographic authorization
3. **Validation Registry** -- Third-party assessments (zkML, TEE, staker)

Reference implementation: [erc8004-cairo](https://github.com/Akashneelesh/erc8004-cairo)

## Prerequisites

```bash
npm install starknet
```

## Agent Registration

### Register a New Agent

```typescript
import { Account, RpcProvider, Contract, CallData } from "starknet";

const provider = new RpcProvider({ nodeUrl: process.env.STARKNET_RPC_URL });
const account = new Account({ provider, address, signer: privateKey });

const identityRegistry = new Contract({
  abi: identityRegistryAbi,
  address: registryAddress,
  providerOrAccount: account,
});

// Register with metadata
const metadata = [
  { key: "agentName", value: "MyTradingAgent" },
  { key: "agentType", value: "defi-trader" },
  { key: "version", value: "1.0.0" },
  { key: "model", value: "claude-opus-4-5" },
  { key: "status", value: "active" },
];

const tokenUri = "ipfs://QmYourAgentSpecHash"; // IPFS link to full agent spec
