A novel Ethereum Improvement Proposal, EIP-8004 “Trustless Agents,” is set to make Ethereum the go-to platform for AI agents. With ERC-8004, Ethereum will become technically capable of hosting autonomous AI agents. To ensure the execution of economical tasks—from ordering goods to sophisticated actions like prediction market bets or liquidity provision—EIP-8004 brings entirely new structures to Ethereum. Three lightweight registries can be deployed on any L2 or on the mainnet as per-chain singletons.
Identity Registry provides portable, censorship-resistant identifiers via a minimal on-chain handle based on ERC-721 that resolves to an agent’s registration file. Reputation Registry is a standard interface for posting and fetching feedback signals. Scoring and aggregation occur both on-chain (for composability) and off-chain (for sophisticated algorithms), enabling an ecosystem of specialized services for agent scoring, auditor networks and insurance pools.
Validation Registry is a set of generic hooks for requesting and recording independent validator checks (e.g., stakers rerunning the job, zkML verifiers, TEE oracles, trusted judges). The proposal is under review now and could be included in the hard fork agenda this year. Autonomous AI agents—isolated programs that can execute basic economic actions on smart contracts—are a trending topic as the ecosystem evolves toward greater automation.
