Ethereum developers have proposed ERC-8183, a new token standard aimed at allowing AI agents to securely transact with each other. The proposal was co-developed by the Ethereum Foundation and Virtual Protocol to support structured commerce between autonomous agents on-chain.
This standard establishes a trustless escrow system, ensuring that payments are released only after the task is verified. This could be the basis for an emerging “agent economy,” where autonomous programs request, execute, and settle for services on-chain on their own without human oversight.
ERC-8183 builds on existing Ethereum standards, including x402 for micropayments and ERC-8004 for agent identity and reputation. Unlike simple token transfers, this standard focuses on structured commerce and captures every step of a transaction. It formalizes the job between three participants: client, provider, and evaluator.
The client funds the job, the provider completes the task, and the evaluator verifies the delivery before payment is released. If the task is rejected or expires, the funds will be automatically refunded. Therefore, all transactions are transparent, verifiable, and secure.
ERC-8183 is one of the missing pieces of the Ethereum open agent economy we are building.

Extensible jobs and modular hooks
A key innovation in ERC-8183 is a modular hook system that allows developers to extend the core job lifecycle with custom logic. Hooks can enforce preconditions, manage complex capital flows, and integrate external reputation checks. These support a wide range of applications, from content generation and token exchange to risk assessment and privacy protection tasks.
Additionally, hooks enable flexible workflows, allowing work to adapt to new economic models and new use cases. Developers can implement milestone payments, bidding mechanisms, or underwriting processes while maintaining trustless payments.
The standard also separates the interface and core logic. Agents can interact through protocols such as HTTP API or MCP, and the underlying payments occur on-chain.
This separation ensures accessibility and interoperability without compromising security or decentralization. By combining the commerce framework of ERC-8183 and the identity and reputation layer of ERC-8004, this protocol establishes a complete trust infrastructure for autonomous agents.
Building the agent economy of the future
ERC-8183 transforms AI agents into independent economic participants that can produce, provide, and evaluate services. This standard supports both microservices and high-value contracts, enabling a global network of autonomous transactions.
As AI agents become more capable, this protocol ensures that interactions remain trustless, verifiable, and transparent. Developers and facilitators are encouraged to adopt ERC-8183, experiment with new hooks, and register evaluators to grow this open commerce ecosystem.
Importantly, ERC-8183 provides the structural foundation for an agent-driven economy where reputation, verification, and escrow payments replace centralized platforms. This will keep commerce open, secure, and accessible, and lay the foundation for a decentralized, agent-driven digital marketplace.
