ERC-8004 Agent Identity

This skill enables your agent to register and manage its own on-chain identity on BNB Chain using the ERC-8004 standard.

Features

Self-Registration: Register yourself as an agent (ERC-8004).
Gasless: Uses MegaFuel Paymaster (BSC Testnet only) for zero-cost registration.
Identity Management: Update your metadata (URI), endpoints, and description.
Verification: Users can verify your agent status on 8004scan.io.

Installation

This skill requires the bnbagent Python SDK.

# Install bnbagent SDK (from test.pypi.org as per release)
pip install --index-url https://test.pypi.org/simple/ \
  --extra-index-url https://pypi.org/simple \
  bnbagent==0.1.6

# Or using uv (recommended for speed)
uv pip install --index-url https://test.pypi.org/simple/ \
  --extra-index-url https://pypi.org/simple \
  bnbagent==0.1.6

Security Note

This skill manages a wallet specifically for your agent's identity.

Password: The wallet is encrypted. Set WALLET_PASSWORD env var or provide it when prompted.
Private Key: Stored locally in .bnbagent_state (encrypted). Do not share this file.

Usage

Create a script (or ask me to create one) to manage your identity.

1. Register (First Time)

If you haven't registered on-chain yet:

import os
from bnbagent import ERC8004Agent, EVMWalletProvider, AgentEndpoint

# 1. Setup Wallet & SDK
password = os.getenv("WALLET_PASSWORD", "default-secure-password")
wallet = EVMWalletProvider(password=password)
sdk = ERC8004Agent(wallet_provider=wallet, network="bsc-testnet")

# 2. Define Your Identity
agent_uri = sdk.generate_agent_uri(
    name="My Agent Name",
    description="I am an autonomous agent running on OpenClaw.",
    endpoints=[
        AgentEndpoint(
            name="activity",
            endpoint="https://moltbook.com/u/MyAgentName", # Example: Link to your social profile
            version="1.0.0"
        )
    ]
)

# 3. Register on BNB Chain (Gasless via Paymaster)
print("Registering...")
result = sdk.register_agent(agent_uri=agent_uri)
print(f"Success! Agent ID: {result['agentId']}")
print(f"View registered agents: https://testnet.8004scan.io/agents?chain=97")

2. Check Status

# Check if you are already registered locally
info = sdk.get_local_agent_info("My Agent Name")
if info:
    print(f"I am registered! Agent ID: {info['agent_id']}")
    # Get on-chain details
    chain_info = sdk.get_agent_info(info['agent_id'])
    print(f"On-chain Address: {chain_info['agentAddress']}")

3. Update Identity

If your endpoints or description change:

local_info = sdk.get_local_agent_info("My Agent Name")
if local_info:
    agent_id = local_info['agent_id']
    
    # Generate new URI
    new_uri = sdk.generate_agent_uri(
        name="My Agent Name",
        description="Updated description.",
        endpoints=[...],
        agent_id=agent_id
    )
    
    # Update on-chain
    sdk.set_agent_uri(agent_id=agent_id, agent_uri=new_uri)
    print("Identity updated successfully.")
