SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

ERC-8004 provides a standardized trust and discovery layer for autonomous AI agents by linking on-chain identities (NFTs) with human-readable registration data, enabling auditable interactions and verifiable ownership across multiple registries.

Core Features & Use Cases

  • Three registries (Identity, Reputation, Validation) enable portable identity, on-chain feedback, and third-party attestations.
  • Supports cross-chain agent deployment, domain verification, and open-standards-based integrations (MCP/A2A/ENS).
  • Use cases include agent registration, discovery by skills/domains, trust assessment, and integration planning for on-chain workflows.

Quick Start

Host a registration file for your agent and mint its identity NFT on a supported chain.

Frequently Asked Questions about 8004

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
What is ERC-8004 and how does it work for autonomous agent identity?▼

ERC-8004 is a protocol linking on-chain identity NFTs to human-readable registration JSON files, enabling trustless agent discovery and verifiable ownership across multiple chains like chain ID 11155111 or 8453.

How do I register an AI agent on-chain using ERC-8004?▼

To register an agent using ERC-8004, host a registration JSON file for your agent and mint its identity NFT on a supported blockchain to link the on-chain identity with the off-chain data.

Does ERC-8004 support cross-chain agent deployment and reputation tracking?▼

Yes, ERC-8004 supports cross-chain agent deployment through three distinct registries: Identity, Reputation, and Validation, enabling portable identity, on-chain feedback, and third-party attestations.

Can I use ERC-8004 with MCP, A2A, or ENS open standards?▼

Yes, ERC-8004 is designed for open-standards-based integrations, supporting MCP, A2A, and ENS to facilitate domain verification and integration planning for on-chain agent workflows.

How do I interpret ERC-8004 agent IDs like 11155111:42 or 8453:17?▼

ERC-8004 agent IDs like 11155111:42 or 8453:17 represent the chain ID and the specific token identifier, mapping the agent to its identity registry NFT and registration schema for discovery and validation.

What is the best way to assess agent trust using ERC-8004 registries?▼

The best way to assess agent trust is by querying the ERC-8004 Reputation and Validation registries, which provide on-chain feedback signals and third-party attestations for auditable interactions.
