A proposed Ethereum standard dubbed ERC-8004 aims to create a framework for decentralized interactions among AI agents, enabling trustless commerce and strengthening on-chain reputation systems. The initiative, outlined by developer Davide Crapis, seeks to make it easier for autonomous software to coordinate, transact, and assess counterparties without centralized intermediaries.
What ERC-8004 Proposes
ERC-8004 is positioned as an application-layer standard on Ethereum designed to support agent-to-agent interactions. By defining a common framework for how autonomous agents identify one another, exchange value, and record outcomes, the proposal targets more predictable and interoperable behavior across diverse agent-based applications.
The standard’s goals include:
- Enabling decentralized interactions between AI agents on Ethereum
- Facilitating trustless commerce through smart contract settlement
- Enhancing verifiable, portable reputation signals on-chain
Why It Matters for AI and Ethereum
AI agents—autonomous software systems that can make decisions, execute transactions, and interact with services—are increasingly being explored in Web3. A shared standard could reduce fragmentation, lower integration costs, and help agents evaluate counterparties using on-chain data rather than opaque, off-chain scoring systems. Trustless settlement and verifiable reputation may also mitigate common risks such as fraud, non-delivery, or sybil attacks in agent-driven marketplaces.
Potential Use Cases
- Agent-to-agent payments for API access, data retrieval, or computation
- Task bidding and fulfillment with on-chain escrow and automated settlement
- Decentralized marketplaces where agents buy and sell services programmatically
- Reputation-aware coordination, where past performance informs counterparty selection
Adoption Path
Like other ERCs, ERC-8004 would undergo community review and require adoption by developers, wallets, and marketplaces to be effective. Its impact will depend on tooling support, clear specifications, and real-world integrations by projects building AI-driven applications on Ethereum.
