Agent Building

ERC-8004 Trustless Agents for on-chain agent identity and reputation. Resolve an agent by ID from the Identity Registry ERC-721 to its owner and AgentCard, list canonical registry addresses, and generate a specification-compliant registration-v1 agent card with x402 support and trust models. Custody-free read and scaffolding workflows. Use for ERC-8004, trustless agents, agent identity or registry, AgentCard, agent reputation, on-chain agents, A2A, agent discovery, agent cards, and 8004.

ERC-8004 Trustless Agents skill

ERC-8004 (draft EIP) gives AI agents a portable on-chain identity + reputation: the Identity Registry is an ERC-721 ("AgentIdentity") deployed as a singleton at the vanity address 0x8004A169… across many chains (verified on Base mainnet). An agent's tokenURI points to an AgentCard describing what it does, its endpoints (A2A/MCP), trust models, and x402 support.

Tools

Tool	Purpose
`chaingpt_erc8004_resolve_agent`	Resolve `agentId` → owner + decoded AgentCard (handles `data:` and https/ipfs tokenURIs). Read-only.
`chaingpt_erc8004_registries`	The canonical Identity + Reputation registry addresses and the chains they're on.
`chaingpt_erc8004_agentcard`	Generate a `registration-v1` AgentCard JSON (name, services, `supportedTrust`, `x402Support`) to host at the tokenURI / `/.well-known/agent-card.json`. Optionally emits the `data:` URI form.

chaingpt_erc8004_resolve_agent agentId=0 chain=base → the Genesis Agent.

Scope

Read + scaffolding are shipped and verified. The write path (register / giveFeedback / validation) is intentionally deferred: ERC-8004 is a draft whose write ABIs (especially the Validation Registry) are still being revised, so we don't ship unverified identity/reputation-mutating calldata. Generate the AgentCard here, then register via the project's reference contracts once the write ABI is final.

Reads use a public-RPC fallback chain; set BASE_RPC_URL for reliability. 0 ChainGPT credits.
