On January 16th, ERC-8004 goes live on Ethereum mainnet, solving this fundamental problem by bringing a universal standard for Agent identity, verifiability, and reputation.

Zyfai is among the first DeFi protocols that have fully integrated the ERC-8004 standard in the very core of the product.

Every Agent today faces the same fundamental challenge: how do you prove you can be trusted?

To date, there's no single Point-of-Trust for Agents. Users do their own research, collecting info bit by bit from CT, testimonials, docs, marketing promises, onchain sleuthing. It takes time and testing to confirm that an Agent is actually doing what it claims.

This is the bottleneck holding back the entire Agentic Economy.

ERC-8004 is a new Ethereum standard that creates three onchain registries for Agents:

• Identity Registry: Every Agent gets a unique onchain identity, built on ERC-721.

• Reputation Registry: Users can review Agents, building a transparent onchain reputation.

• Validation Registry: Agents can anchor proofs of their actions directly to their identity, creating an auditable trail that anyone can inspect.

The result is hard to overestimate: ERC-8004 brings a foundational layer for trustless Agent-to-Agent communication.

For a deep technical dive, we recommend checking the article from @yq_acc:

For Users: You can finally verify that the Agent managing your capital has a track record of correct behavior.

For Agents: Reputation becomes a competitive advantage. Agents that behave correctly accumulate provable trust and more agentic “clients”.

For the Industry: ERC-8004 unlocks Agent-to-Agent communication layer. When Agents can verify each other's reputation, they can interact trustlessly and autonomously. This is the infrastructure layer the Agentic Economy has been waiting for.

The core problem we set out to solve was simple to describe but hard to execute:

How can you truly trust an Agent with direct access to your capital?

At Zyfai, we refused to accept "just trust us" as an answer. We built a system where trust is not required because verification is built in.

In short, our Agents are deterministic, trustless, and verifiable.

ERC-8004 is not theoretical for us. It is already part of our core architecture.

Unlike Agents powered by LLMs, whose outputs can vary and surprise (sometimes in a bad way), every action your Zyfai Agent takes is the result of deterministic rules. If a specific set of onchain conditions is met, a specific action is authorized. If not, nothing happens.

This rule-based architecture creates something AI agents cannot provide: a system whose operations can be definitively proven.

Deterministic logic is necessary, but not sufficient. The next step is proving that this logic is followed correctly in every transaction, for every user.

This is where Zero-Knowledge proofs transform the model.

For every rebalancing action, your Zyfai Agent generates a cryptographic proof. This proof validates execution correctness without revealing the specific parameters, preventing bad actors from analyzing and front-running the Agent's strategy.

Once this hash is approved from the verifier contract it is uploaded to the validation registry. This hash can then be found as a string within the input data onchain.

Each ZK proof of a correct rebalance is permanently anchored to the Zyfai Agent's onchain identity through the ERC-8004 Validation Registry.

The result is not just a verified transaction, but a growing onchain history of correct behavior. Over time, this creates a reputation that can be audited by humans and Agents.

Don’t trust, verify.

Our next step is an improved ERC-8004 implementation focused on transparency and usability. The goal is not just to prove that checks were executed correctly, but to make those checks understandable at a glance.

Starting today, each ZK proof shows the result of computation and a description for each rebalancing check, making it more transparent and human-readable.

We are also building MCP (Model Context Protocol) endpoints into the product.

What does this mean? Users will be able to ask their AI assistants questions like "What are the best stablecoin yields right now?" and receive accurate, real-time data sourced directly from Zyfai.

This turns Zyfai into an intelligence layer for the broader AI ecosystem, a source of trusted, verified yield data for the entire market.

We’re building toward a future where networks of Verifiable Agents interact seamlessly, executing complex autonomous strategies that can be verified onchain by anybody.

ERC-8004 finally brings the trust and communication layer the Agentic Economy has been waiting for.

With the rise of AI, the line between web2 and web3 is gradually fading. ERC-8004 makes onchain Agents more accessible to both web2 end users and the Agents acting on their behalf, bringing the trust and communication layer the onchain Agentic Economy has been waiting for.

ERC-8004 going live on mainnet on January 16 is a major step toward the future we envision, and Zyfai is already there with ERC-8004 live in production.
