The Ethereum community is currently abuzz with the emergence and discussions around a new standard ERC-8004, dubbed Trustless Agents. This newly unveiled development promises to revolutionize the interaction of autonomous AI agents in a trustless environment like Ethereum Network.
Introduced by Davide Crapis, the Trustless Agents standard builds on the Agent-to-Agent (A2A) protocol and has sparked a flurry of discussions within Ethereum developers, researchers, and blockchain enthusiasts weighing in on its potential to shape a decentralized AI economy.
“This standard extends the Agent‑to‑Agent (A2A) protocol with a trust layer that allows participants to discover, choose, and interact with agents across organizational boundaries without pre‑existing trust,” Crapis stated in a latest Ethereum Magicians post,” adding, “It introduces three lightweight, on‑chain registries—Identity, Reputation, and Validation—and leaves application‑specific logic to off‑chain components.”
Crapis said that while this proposed ERC goes for public discussion, his team will work closely with the Linux Foundation and A2A ecosystem stakeholders to make it efficient and improve its specifications.
The proposal positions Ethereum as a critical substrate for AI, not for running models directly but for providing a secure, tamper-proof ledger that no single corporation or government can alter. This vision contrasts sharply with reliance on centralized platforms like Google APIs or proprietary databases, a concern amplified by growing distrust in corporate data control.
What Exactly are ERC-8004 and Trustless Agents
From the technical perspective, ERC-8004 is currently a proposed smart-contract standard on Ethereum. It can simply be understood with the approach of NFT smart contracts, which follows ERC-721 Ethereum standard. For simple tokens, ERC-20 is the most commonly used standard.
The proposed ERC-8004 standard extends the A2A protocol—an open infrastructure developed by Google in collaboration with 50+ partners—by introducing a trust layer that enables AI agents to discover, choose, and interact across organizational boundaries.
It leverages three lightweight on-chain registries: Identity, Reputation, and Validation. These registries provide a verifiable anchor for agent identity, an immutable record of behavior, and proofs of action, respectively, while leaving application-specific logic to off-chain components.
Scope for the Trustless Agents
Explaining the importance of Trustless Agents, an anonymous member of the Ethereum Foundation, Binji stated that ERC-8004 could serve as the backbone of a “machine economy,” where millions of autonomous agents operate. They can transact, negotiate, and form coalitions—potentially even decentralized autonomous organizations (DAOs).
ethereum is SERIOUSLY gearing up for ai. (erc-8004) by @DavideCrapis just dropped, it’s called “trustless agents” and here’s what you need to know:

you can think of ethereum as an important substrate for ai, not necessarily because it can run all the models, but… pic.twitter.com/cxP8OR1CTB

“This is a practical ERC that can be used and iterated on in the wild; the specifics can stay offchain, but the skeleton of trust lives on ethereum,” Binji wrote.
While the demand for AI infrastructure is rising, Trustless Agents could gain significant traction. It sits on the intersection of both the emerging sectors—decentralized technologies and artificial intelligence—which are rising trends across a number of innovations.
The Road Ahead
As ERC-8004 undergoes public discussion, developers are working closely with the Linux Foundation—which is hosting the A2A protocol—and A2A team to refine the specification. With Ethereum Layer 2 solutions addressing scalability hurdles, the standard could lay the foundation for a sci-fi future where AI agents operate autonomously on a decentralized trust layer.
If passed for implementation, ERC-8004 could reshape Ethereum’s role as a decentralized infrastructure provider. For now, the Ethereum community remains cautiously optimistic, with many viewing ERC-8004 as a critical step toward a decentralized AI economy.
