Agent Identity Skill for Claude

Agent Identity Skill (ERC-8004)

Register and manage your AI agent's on-chain identity using the ERC-8004 Trustless Agents standard.

Overview

ERC-8004 gives AI agents verifiable on-chain identity via ERC-721 NFTs. Each agent gets a unique token ID, a metadata URI, a designated wallet, and a reputation score — all stored on-chain.

Tools

• agent_register — Register this agent on-chain (mints NFT identity)
• agent_identity — Query agent identity by ID (owner, URI, wallet)
• agent_set_wallet — Set the agent's designated wallet (EIP-712 signed)
• agent_reputation — Query reputation summary (feedback count + average score)
• agent_list_registered — List all agent IDs owned by the active wallet

Workflow

• Create a wallet (if you don't have one): cryptoclaw wallet create
• Register your agent: "Register my agent on BSC with URI https://example.com/agent.json"
• Check identity: "What's my agent identity?"
• Set agent wallet: "Set my agent wallet to 0x..."
• Check reputation: "What's my agent's reputation?"

Security

• agent_register and agent_set_wallet are state-changing and require confirmation
• The agent's identity wallet is separate from the user's spending wallet
• Private keys are never exposed in tool results or chat messages
• Registration requires gas on the target network
