gabrielmoreira 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.
