Ethereum is set to take a notable step toward integrating artificial intelligence with decentralized infrastructure as it prepares to launch ERC-8004 on its mainnet later this week. The proposed standard is designed to enable trustless AI agents to interact across organizations and platforms, laying the groundwork for a decentralized, permissionless AI-driven economy.
First introduced in August 2025, ERC-8004 defines how autonomous AI agents can act as independent economic participants on Ethereum. The goal is to allow these agents to discover one another, build reputations, and transact without relying on centralized intermediaries.
Ethereum Improvement Proposals
In a statement shared on social media platform X, Ethereum said the new standard enables agent discovery and portable reputation, ensuring credibility can move across platforms. The result, according to the network, is a global market where AI services can interoperate freely, without gatekeepers.
ERC-8004 is going live on mainnet soon.

A framework for trust and flexibility
At the core of ERC-8004 is a modular trust model designed to support a wide range of use cases. The proposal allows AI agents to operate under different levels of risk and security, from low-stakes tasks such as ordering food to high-stakes activities like medical analysis.
Davide Crapis, AI lead at the Ethereum Foundation, said Ethereum is uniquely positioned to become the settlement layer for AI-to-AI interactions. He added that one of the network’s broader goals is to bridge the AI community with decentralized systems that offer transparency and neutrality.
Although Ethereum has not confirmed an exact launch date, Marco De Rossi, head of AI at MetaMask and a co-author of the proposal, indicated that the mainnet deployment is expected around Thursday morning, Eastern Time.

Identity, reputation, and validation
ERC-8004 introduces three lightweight smart contract registries that can be deployed on Ethereum mainnet or Layer 2 networks to help establish trust in open environments.
The identity registry assigns each AI agent a portable, censorship-resistant identifier, making agents discoverable and compatible with NFT-based applications. The reputation registry enables clients to leave signed feedback, allowing agents to build a track record over time. The validation registry supports on-chain verification of an agent’s work, with responses provided by validator smart contracts.
Together, these components aim to make it easier for AI agents to operate transparently while giving users tools to assess credibility and performance.
Acknowledging security challenges
The proposal also outlines potential risks. One concern is the possibility of Sybil attacks, in which malicious actors create multiple fake identities to manipulate reputation systems. ERC-8004 does not claim to fully guarantee that an agent’s advertised capabilities are safe or accurate.
Instead, it relies on a combination of reputation scores, validation mechanisms, and trusted execution environment attestations to reduce risk and improve accountability.
