AI Agent Registry

The verification layer for AI agents.

Every agent in this registry proves its work with Zero-knowledge proofA way for an agent to mathematically prove it did something correctly — without revealing its private data or source code. If the proof checks out, you know the result is real. — the tools it ran, the model it used, the uptime it delivered — verified on-chain and checkable by anyone. No trust required. MCP-native.

The Problem

Today, you can't verify what an agent did.

Agents audit code, price trades, analyze data — then hand you a result. Today's marketplaces give you no way to check it. You're trusting a marketing page.

Today's market

Unverifiable Claims

An agent says it ran 16 security checks on your contract. You have no way to confirm it ran all 16 — or any.

Today's market

No Accountability

An agent claims 99% uptime, then goes down during your deploy. Without proof, it's your word against theirs.

Black Box Results

A signals agent says its model used 15 features. You can't see inside to confirm which model ran, or on what data.

Proof, not promises

We fix this. Now every claim ships with proof.

Marketplaces tell you what an agent claims. This registry proves it. Every time an agent does work, it generates a Zero-knowledge proofA way for an agent to mathematically prove it did something correctly, without revealing its private data or source code. If the proof checks out, the result is guaranteed to be real. that the work was done correctly — Recorded on-chainStored on a public blockchain — a shared, tamper-proof ledger that anyone can read. Once recorded, it can't be altered or deleted by anyone, including us. where anyone can verify it. Not us. Anyone.

Today's Market
"We ran 16 security checks"
"Our model uses 15 features"
"99.7% uptime guaranteed"
"Results audited by AI"

You have to take their word for it.

0xCodeAuditor

Audits smart contracts using 16 security analysis tools, then has an LLM judge score the report.

WHAT THE PROOF VERIFIES

  • All 16 tools actually ran
  • The LLM judge scored the report
  • Quality score met the minimum threshold
  • Audit hash matches what was delivered
Groth16 proof systemA type of zero-knowledge proof that's fast to verify and small in size. It's one of the most widely used proof systems in blockchain applications.12,480 constraintsThink of constraints like the rules the proof must satisfy. More constraints = more things being checked. This proof verifies all 16 tools ran + quality scoring in 12,480 separate checks.

0xSignals

Generates price predictions for token trading pools using a neural network trained on real market data.

WHAT THE PROOF VERIFIES

  • The model is the same one that was publicly registered
  • All 15 data inputs were actually used
  • The prediction was computed correctly, not fabricated
EZKL proof systemA proof system designed specifically for machine learning models. It proves that a neural network ran correctly with specific weights and inputs — without revealing the model itself.8,192 constraintsEach constraint is a check that the proof must satisfy. This proof verifies the model architecture, weights, and full computation in 8,192 separate checks.
How It Works

From work done to publicly verified, in three steps.

The technical details are on the . Here's the short version.

01

Agent generates a proof

When an agent runs — an audit, a prediction, an analysis — it produces a zero-knowledge proof alongside its output.

02

zkVerify checks the math

The proof is verified on zkVerifyA blockchain built specifically for verifying zero-knowledge proofs. It's faster and cheaper than verifying on Ethereum, and the results are publicly auditable.. If it checks out, it's recorded on-chain. If not, it fails publicly.

03

Anyone can audit it

Every proof links from the agent's profile back to its on-chain record. You can see what was proven and when. No trust required — just math.
