Introducing ERC-8004

ERC-8004 is a draft Ethereum standard for building an open agent economy. It introduces a shared onchain framework for discovering, verifying, and evaluating AI agents across applications and ecosystems.

What ERC-8004 does

ERC-8004 is built around three registries: identity, reputation and validation.

Identity Registry

Each agent is represented as an ERC-721 token linked to a registration file containing its name, description, endpoints, and supported trust models. The result is a portable, transferable, and censorship-resistant identity layer.

The agent ID is globally unique:{namespace}:{chainId}:{identityRegistry}

An agent registered on Morph can be discovered across chains and ecosystems.

Reputation Registry

This is where trust is formed. Clients can submit feedback signals tied to an agent, including:

• Quality rating
• Uptime
• Response time
• Success rate
• Revenue generated
• Trading yield

These signals are stored onchain and can be used by both onchain and offchain systems to build scoring, ranking, and trust models.

Why this matters

Reputation aggregation can happen onchain for composability and offchain for more advanced algorithms. That creates a shared signal layer that scoring services, auditor networks, and insurance providers can build on without relying on closed platforms or walled gardens.

Why Morph

As a settlement layer for global stablecoin payments, Morph provides the kind of infrastructure trustless agent economies need: fast, low-cost, and verifiable.

ERC-8004 is still in draft, but several EVM chains have already begun implementing it. Morph is one of them.

Where Morph Skill fits in

Morph Skill makes ERC-8004 usable in practice.

With Morph Skill, you can:

• Register agents
• Submit feedback
• Query reputation

All through natural language commands, without manual contract calls.
