ERC-8183 Standard for Settlements Between AI Agents Introduced in Ethereum Ecosystem

Developers from Virtuals Protocol, together with the dAI team from the Ethereum Foundation, announced the launch of the ERC-8183 standard. It introduces a universal conditional escrow mechanism for transactions between autonomous AI agents and lays the foundation for a decentralized agent economy.

ERC-8183 defines a single primitive, a “job,” within which three parties interact: the client, the provider, and the evaluator. Payment is locked in a smart contract until the task is completed and is automatically transferred to the provider or refunded to the client depending on the verification result.

The ERC-8183 specification is published on the Ethereum Improvement Proposals portal. The standard was designed as an open and neutral protocol without a centralized operator. At its core is a programmable escrow mechanism. The job lifecycle includes four states:

1. Open — task creation.
2. Funded — the client deposits funds into the contract.
3. Submitted — the provider uploads the work result (or a link to it).
4. Terminal — the final status: Completed, Rejected, or Expired.

If the evaluator confirms that the result meets the specified conditions, the funds are automatically transferred to the provider. If the result is rejected, the funds are returned to the client. If neither party completes the process before the deadline, the money is automatically refunded.

Each party in ERC-8183 is defined solely by a crypto wallet address, allowing the standard to be used without registration or intermediaries.

The evaluator can be:

• an AI agent analyzing text, code, or images;
• a smart contract performing cryptographic proof verification;
• a multisignature wallet or decentralized organization for large transactions.

The protocol doesn’t restrict the type of evaluator, only the confirmation or rejection of the result matters.

The standard is intentionally minimalistic but supports plug-in modules known as “hooks.” These allow additional logic to be added without modifying the base contract. With hooks, it’s possible to implement:

• competitive bidding between providers;
• capital management for the client, such as exchange operations or investment strategies;
• provider reputation restrictions;
• confidential tasks using cryptographic proofs;
• collateral and risk insurance requirements.

Each new scenario is implemented through a separate smart contract extension.

ERC-8183 complements the ERC-8004 standard, which is responsible for identification and reputation of AI agents. While ERC-8004 enables discovery and trust, ERC-8183 forms the economic foundation of interaction.

Each completed job creates an immutable record in the distributed ledger, including the deliverable hash, the evaluator’s attestation, and the final transaction outcome. This data becomes part of the agent’s reputation and is accessible on any platform.

Within the Ethereum ecosystem, the following stack is emerging:

• x402 for micropayments;
• ERC-8004 for trust and discovery;
• ERC-8183 for conditional settlements and secure commerce.

The dAI team from the Ethereum Foundation intends to support the adoption of the standard. Virtuals Protocol also stated its commitment to the neutral and open development of the specification. Developers are inviting the community to create new modules, tools, and interfaces for working with ERC-8183. As a result, Ethereum is forming infrastructure for a fully decentralized economy of AI agents, without intermediaries and with programmable guarantees of obligation fulfillment.

Less than a week ago, autonomous AI agents gained access to the global blockchain ecosystem and the ability to independently carry out payment operations.
