Trustless AI agent standard could hit Ethereum mainnet on Thursday

4 hours ago

An Ethereum astute declaration modular enabling trustless artificial quality cause connection connected the web is “probably” going to beryllium deployed connected mainnet connected Thursday, according to Marco De Rossi, caput of AI astatine MetaMask.

Further improvement of ERC-8004 has been “frozen [...] and we volition spell to mainnet midweek, astir apt astir Thursday, 9 AM ET,” said De Rossi connected a Telegram transmission for developers of the protocol connected Monday. 

On Tuesday, the authoritative Ethereum X relationship said the protocol is going unrecorded connected mainnet “soon.” 

“By enabling find and portable reputation, ERC-8004 allows AI agents to interact crossed organizations, ensuring credibility travels everywhere,” it explained. 

The Ethereum Request for Comment proposes a modular mode to registry and validate AI agents. Developers tin instrumentality it successful their astute contracts, and it does not necessitate immoderate changes to the Ethereum web itself.

The connection explains that the protocol is designed for discovering, choosing, and interacting with agentic AI crossed organizational boundaries without pre-existing trust, enabling unfastened cause economies connected blockchain.

The modular solves 2 halfway problems: however to find AI agents and however to cognize which agents are reliable.

While protocols similar MCP (Model Context Protocol) and Agent2Agent grip cause communication, skills advertising, and task orchestration, they don’t code find oregon trust. 

“To foster an open, cross-organizational cause economy, we request mechanisms for discovering and trusting agents successful untrusted settings.”

“Ethereum is successful the unsocial presumption to beryllium the level that secures and settles AI-to-AI interactions,” said AI pb astatine the Ethereum Foundation, Davide Crapis, connected Tuesday.

AI services tin interoperate without gatekeepers

The modular volition besides enactment connected the Ethereum layer-2 Base, according to developers connected Telegram, but they did not supply a clip framework for deployment. 

Base uses x402, an unfastened outgo protocol developed by Coinbase and introduced successful May 2025, which enables instant, automatic stablecoin payments straight implicit HTTP, empowering AI agents to wage for services autonomously.

The motorboat of ERC-8004 provides the missing portion that lets AI agents go economical actors alternatively than conscionable isolated, siloed tools.

“This unlocks a planetary marketplace wherever AI services tin interoperate without gatekeepers,” stated the Ethereum relationship connected X.
