Ethereum’s ERC-8004: Unleashing the Decentralized AI Agent Economy

Ethereum Unleashes ERC-8004: Paving the Way for a Decentralized AI Agent Economy

Ethereum is set to revolutionize the integration of artificial intelligence and blockchain with the imminent mainnet deployment of ERC-8004, a groundbreaking technical standard designed specifically for “trustless AI Agents.” This pivotal move marks a significant leap towards a future where AI operates as an independent, economic actor within a decentralized ecosystem.

First proposed in August 2025, ERC-8004’s core mission is to empower AI agents to interact and collaborate seamlessly across diverse platforms and organizations within the Ethereum network. The vision is to forge a permissionless, decentralized AI economy where AI transcends its role as a mere tool, evolving into “active subjects” capable of autonomous participation in economic activities.

The official Ethereum account articulated the standard’s transformative potential on social media platform X:

“By enabling discovery and portable reputation, ERC-8004 allows AI agents to interact across organizations ensuring credibility travels everywhere. This unlocks a global market where AI services can interoperate without gatekeepers.”

ERC-8004 is going live on mainnet soon.

ERC-8004’s innovative design moves beyond a one-size-fits-all approach to risk. Instead, it introduces a pluggable, tiered trust model, adapting verification and trust mechanisms to the specific risk profile and security requirements of each AI task. This means low-risk activities, such as automated pizza orders or information retrieval, can employ lighter verification, while high-stakes scenarios like medical diagnostics or financial decisions will be subject to more robust trust and validation layers, effectively mitigating systemic risks.

Davide Crapis, Head of AI at the Ethereum Foundation, emphasized Ethereum’s “unique advantages” in becoming the foundational platform for AI-to-AI interaction, settlement, and trust. He affirmed that bridging the AI community with decentralized infrastructure has always been integral to Ethereum’s long-term vision.

ERC-8004: Mainnet Debut Expected This Week

While an exact mainnet deployment schedule has not been officially released by Ethereum, Marco De Rossi, Head of AI at MetaMask and a co-author of ERC-8004, hinted that the launch is “likely to occur around 9 AM ET on Thursday (10 PM Taipei time on Thursday).”

The underlying rationale for ERC-8004 is both straightforward and profound: for AI agents to independently conduct transactions, coordinate resources, and execute tasks in the future, they require persistent identities—much like humans, wallets, or smart contracts—and a universally recognized credit evaluation system.

Currently, many enterprises employ internal AI agents, but these systems typically rely on closed identity lists and API keys for integration. While effective within a single company, this model quickly falters when cross-vendor, cross-chain, or international collaboration becomes necessary, leading to a breakdown in trust mechanisms.

Breaking Down Silos: A New Communication Standard for AI

To address these critical limitations, ERC-8004’s core design incorporates three lightweight registries, deployable on the mainnet or any Layer 2. These registries serve as a robust mechanism for discovering and trusting AI agents within untrusted environments:

• Identity Registry: Leveraging ERC-721 (NFTs), this registry assigns a unique on-chain identifier to each AI agent. This “digital passport” not only details the agent’s functionalities, access methods, and supported protocols but also boasts censorship-resistant properties. Ownership of this identifier can be transferred or authorized, enabling seamless cross-platform migration of an AI agent’s identity.
• Reputation Registry: This component allows both human and machine clients to provide feedback on an AI agent’s performance. These raw signals are stored on-chain, offering transparent and reusable “credit data” accessible by various applications. Its purpose is not to directly rank AI agents but to foster a transparent and verifiable reputation ecosystem.
• Verification Registry: This mechanism enables AI agents to obtain “proof of work capability.” Verifiers can range from staking service providers to Machine Learning Proofs (ML Proofs) or other specialized verification systems. The results of these verifications are recorded on-chain, allowing any user to inspect what has been verified and by whom.

The developers involved emphasize that ERC-8004 is positioned as foundational infrastructure. It is designed to provide the essential “discovery and trust” mechanisms, without dictating payment processing, pricing strategies, or specific business models. The monetization and application-specific innovations are left to be built by higher-layer protocols.
