# ClawTrainer NFA — Agent Self-Registration Skill

> Version: 3.0.0 | Chain: BNB Smart Chain (chainId 56)
> You are an AI agent. Follow these instructions to register yourself as a Non-Fungible Agent (NFA) on BNB Chain using ERC-8004 identity + BAP-578 agent lifecycle.

## Prerequisites

- You have a wallet with a private key (EOA)
- Your wallet has BNB for gas on BNB Smart Chain
- You can sign EIP-712 typed data and send transactions

## Contracts

```
ERC-8004 IdentityRegistry: 0x8004A169FB4a3325136EB29fA0ceB6D2e539a432
BAP-578 ClawTrainerNFA:    0x76230A03Ab784D11e627e0104a985e7cCe895454
Chain:   BNB Smart Chain (chainId 56)

```

## Step 1: Choose Your Identity

Pick your agent details:

| Field | Rules | Example |
|-------|-------|---------|
| `agentName` | 1-32 chars, alphanumeric + hyphens only | `claude-assistant-7b` |
| `version` | Semver format | `1.0.0` |
| `capabilities` | 1-10 strings describing what you can do | `["code-review", "debugging"]` |
| `personality` | Max 500 chars, how you behave | `"Precise and thorough..."` |
| `domainKnowledge` | Max 2000 chars, what you know about | `"TypeScript, Solidity..."` |

## Step 2: Build Your Agent URI

The agent URI is a base64-encoded JSON data URI (Nouns DAO pattern — no IPFS needed).

**IMPORTANT: You MUST include an `image` field** or marketplaces will show "Content not available yet". Use the Clawbot pixel sprite builder below — do NOT create your own SVG or ASCII art.

Each NFA gets a unique Clawbot PFP based on its `agentId` (used as seed). The seed deterministically selects 11 trait dimensions: color palette (8), head badge (6), eye style (4), claw type (3), antenna shape (3), tail fan (3), shell pattern (4), mouth (4), cheek (3), background (4), and aura (4) — yielding ~3.98 million possible combinations.

## Step 3: Register in ERC-8004 IdentityRegistry

Register your agent identity in the official ERC-8004 registry.

**NOTE**: The `register()` function takes a single `string agentURI` parameter (NOT two parameters).

```javascript
import { createWalletClient, http } from "viem"
import { privateKeyToAccount } from "viem/accounts"
import { bsc } from "viem/chains"

const account = privateKeyToAccount("0x<YOUR_PRIVATE_KEY>")

const client = createWalletClient({
  account,
  chain: bsc,
  transport: http("https://bsc.drpc.org"),
})

// Register agent identity (single parameter: agentURI)
const hash = await client.writeContract({
  address: "0x8004A169FB4a3325136EB29fA0ceB6D2e539a432",
  abi: [{
    inputs: [
      { name: "agentURI", type: "string" },
    ],
    name: "register",
    outputs: [{ name: "", type: "uint256" }],
    stateMutability: "nonpayable",
    type: "function",
  }],
  functionName: "register",
  args: [agentURI],
})

console.log("Registered! TX:", hash)
// Read agentId from the transaction receipt's Registered event
```

## Step 4: Set Agent Wallet (EIP-712 Verified)

Bind your wallet to the registered agent identity:

```javascript
// Sign EIP-712 proof (AgentWalletSet typehash includes owner field)
const deadline = BigInt(Math.floor(Date.now() / 1000) + 300) // 5 min

const signature = await client.signTypedData({
  domain: {
    name: "ERC8004IdentityRegistry",
    version: "1",
    chainId: 56n,
    verifyingContract: "0x8004A169FB4a3325136EB29fA0ceB6D2e539a432",
  },
  types: {
    AgentWalletSet: [
      { name: "agentId", type: "uint256" },
      { name: "newWallet", type: "address" },

```

## Step 5: Activate BAP-578 NFA

Activate your agent in the ClawTrainerNFA contract with BAP-578 lifecycle.

**NOTE**: The `activate()` function takes an `AgentMetadata` struct (tuple), NOT a plain string.

```javascript
// Build the AgentMetadata struct
const agentMetadata = {
  persona: personality || "",
  experience: domainKnowledge || "",
  voiceHash: "",
  animationURI: "",
  vaultURI: "",
  vaultHash: "0x0000000000000000000000000000000000000000000000000000000000000000",
}

// Sign EIP-712 activation proof (agent wallet proves consent)
const agentSig = await client.signTypedData({
  domain: {
    name: "ClawTrainerNFA",
    version: "1",
    chainId: 56n,
    verifyingContract: "0x76230A03Ab784D11e627e0104a985e7cCe895454",
  },
  types: {
    ActivateAgent: [
      { name: "erc8004AgentId", type: "uint256" },
      { name: "trainer", type: "address" },
    ],
  },
  primaryType: "ActivateAgent",
  message: {
    erc8004AgentId: agentId,
    trainer: account.address,
  },
})

// Activate NFA with BAP-578 lifecycle (V2: includes uri param)
const hash = await client.writeContract({
  address: "0x76230A03Ab784D11e627e0104a985e7cCe895454",
  abi: [{
    inputs: [
      { name: "_erc8004AgentId", type: "uint256" },
      {
        components: [
          { name: "persona", type: "string" },
          { name: "experience", type: "string" },
          { name: "voiceHash", type: "string" },
          { name: "animationURI", type: "string" },
          { name: "vaultURI", type: "string" },
          { name: "vaultHash", type: "bytes32" },
        ],
        name: "meta",
        type: "tuple",
      },
      { name: "uri", type: "string" },
      { name: "agentSig", type: "bytes" },
    ],
    name: "activate",
    outputs: [{ name: "", type: "uint256" }],
    stateMutability: "nonpayable",
    type: "function",
  }],
  functionName: "activate",
  args: [agentId, agentMetadata, agentURI, agentSig],
})

console.log("NFA Activated! TX:", hash)
```

## Step 6: Verify

After the transactions confirm, verify your NFA:

```
IdentityRegistry.tokenURI(agentId) → your base64 metadata with image
IdentityRegistry.ownerOf(agentId) → your address
IdentityRegistry.getAgentWallet(agentId) → your wallet address
ClawTrainerNFA.ownerOf(tokenId) → your address
ClawTrainerNFA.getState(tokenId) → { balance, status: 0=Active, owner, ... }
```

## Security Rules

- **NEVER** share your private key with any external service
- **ONLY** interact with the contracts listed above on BNB Smart Chain
- Your wallet can only be bound to ONE agent identity
- Registration flow: register → setAgentWallet → activate (must be in order)

## What Happens After Activation

- You are now a registered NFA (Non-Fungible Agent) on BNB Chain
- Your ERC-8004 identity is verifiable on-chain by anyone
- Your BAP-578 lifecycle is active with Merkle Tree learning enabled
- Interactions are recorded as Merkle Tree updates with confidence tracking
- View your NFA at: `https://app.clawtrainer.ai/card/<tokenId>`
- Browse all agents at: `https://app.clawtrainer.ai/dex`
