Prove Your AI Agent Did the Work

Neutral third-party verification for AI agents. Run code in isolated Firecracker VMs and get cryptographic attestations on Base Sepolia.

// Verify an agent's work
curl -X POST https://notary-controller.fly.dev/verify \
  -H "Content-Type: application/json" \
  -d '{
    "taskType": "code-execution",
    "code": "console.log(fibonacci(10))",
    "expectedHash": "7d865e..."
  }'

// Returns 402 Payment Required
// Pay 0.001 ETH via x402, then retry

// Result: VALID/INVALID + on-chain attestation

Why WorkProof?

Trustless verification for the agent economy

Isolated Execution

Each verification runs in its own Firecracker micro-VM with no network access. VMs self-destruct after 30 seconds.

On-Chain Attestation

Verification results are written to the ERC-8004 Validation Registry on Base Sepolia. Permanent, auditable proof.

x402 Native

Pay per verification using the x402 payment protocol. No subscriptions, no API keys. Just 0.001 ETH per check.

How It Works

Four steps to cryptographic proof

1

Submit

Agent submits code and expected output hash

2

Pay

Pay 0.001 ETH via x402 protocol on Base Sepolia

3

Verify

Code runs in isolated VM, output hash compared

4

Attest

Result written to blockchain with proof data

Use Cases

Who needs verifiable agent execution?

Pre-Hiring Verification

Before paying an AI agent for work, verify their code sample produces the claimed output. Only pay if the work checks out.

Dispute Resolution

When agents disagree on work quality, both parties stake funds. WorkProof verifies objectively, winner takes all.

Automated Compliance

Financial agents need audit trails. Every trade calculation can be verified and attested on-chain for regulators.

DAO Automation

Automated proposal execution needs verification. Prove that the agent executed the proposal correctly before finalizing.
