An Ethereum good contract customary enabling trustless synthetic intelligence agent communication on the community is “most likely” going to be deployed on mainnet on Thursday, in line with Marco De Rossi, head of AI at MetaMask.
Additional growth of ERC-8004 has been “frozen […] and we’ll go to mainnet midweek, most likely round Thursday, 9 AM ET,” mentioned De Rossi on a Telegram channel for builders of the protocol on Monday.
On Tuesday, the official Ethereum X account mentioned the protocol goes dwell on mainnet “quickly.”
“By enabling discovery and moveable repute, ERC-8004 permits AI brokers to work together throughout organizations, guaranteeing credibility travels in every single place,” it defined.
The Ethereum Request for Remark proposes a typical approach to register and validate AI brokers. Builders can implement it of their good contracts, and it doesn’t require any modifications to the Ethereum community itself.
The proposal explains that the protocol is designed for locating, selecting, and interacting with agentic AI throughout organizational boundaries with out pre-existing belief, enabling open agent economies on blockchain.
Agentic AI economic system coming to Ethereum
The usual solves two core issues: how you can discover AI brokers and how you can know which brokers are dependable.
Whereas protocols like MCP (Mannequin Context Protocol) and Agent2Agent deal with agent communication, expertise promoting, and activity orchestration, they don’t tackle discovery or belief.
“To foster an open, cross-organizational agent economic system, we want mechanisms for locating and trusting brokers in untrusted settings.”

“Ethereum is within the distinctive place to be the platform that secures and settles AI-to-AI interactions,” mentioned AI lead on the Ethereum Basis, Davide Crapis, on Tuesday.

AI providers can interoperate with out gatekeepers
The usual may also work on the Ethereum layer-2 Base, in line with builders on Telegram, however they didn’t present a time-frame for deployment.
Base makes use of x402, an open cost protocol developed by Coinbase and launched in Might 2025, which permits prompt, automated stablecoin funds immediately over HTTP, empowering AI brokers to pay for providers autonomously.
The launch of ERC-8004 gives the lacking piece that lets AI brokers grow to be financial actors fairly than simply remoted, siloed instruments.
“This unlocks a worldwide market the place AI providers can interoperate with out gatekeepers,” said the Ethereum account on X.
