Verifiable execution for AI agents.

Every action → signed receipt · Every receipt → ENS identity · Anyone → can verify

Trust the proof. Not the agent.

CommandLayer VerifyAgent flow

What just happened?

  1. 1. Agent runs
  2. 2. SDK signs receipt
  3. 3. VerifyAgent checks proof
  4. 4. Tamper = INVALID

If the output changes, the proof breaks.

Verify a Receipt View SDK

SDK + VerifyAgent.eth

Agents don’t make claims — they produce proof.

Wrap → sign → verify. Wrap any agent action, emit a signed CommandLayer receipt, and verify it with VerifyAgent.eth.

import { CommandLayer } from "@commandlayer/agent-sdk";

const cl = new CommandLayer({
  agent: "runtime.commandlayer.eth",
  privateKey: process.env.CL_PRIVATE_KEY_PEM,
  keyId: "vC4WbcNoq2znSCiQ"
});

const result = await cl.wrap("summarize", async () => {
  return { summary: "hello world" };
});

const verified = await cl.verify(result.receipt);
console.log(verified.status);

How verification works

1. Canonicalize

Rebuild deterministic JSON with json.sorted_keys.vC4WbcNoq2znSCiQ.

2. Hash

Recompute SHA-256 and compare with metadata.proof.hash_sha256.

3. Resolve

Resolve signer identity and key metadata through ENS when available.

4. Verify

Validate the Ed25519 signature and return VERIFIED or INVALID.

If the output changes, the proof breaks.

VerifyAgent.eth is the public verification layer for CommandLayer receipts.

VerifyAgent resolves signer keys from ENS TXT records.
For the hackathon demo, runtime.commandlayer.eth is supported via a labeled fallback resolver that mirrors the ENS record structure.
The verification flow is designed to operate against live ENS records.
