AI's every decision,
on the record.

Drop in one SDK call. Every output your AI agent produces gets a cryptographic receipt — independently checkable by your customers, your auditor, your insurer, your regulator.

87%of enterprise CEOs we interviewed name AI output verification as their #1 deployment bottleneck.

“The model is not the bottleneck anymore.
Trusting what it just did is.”

COUNTDOWN

T-minus 55 days· August 2, 2026

Article 12 requires automatic event logging across the AI system's lifecycle — traceable, tamper-resistant, retained 6+ months.

The receipt your auditor will ask for in 18 months is the same receipt we cut on day one.

The receipt question

You already log this. A log is not a receipt.

Your database keeps a record for you. A receipt is what you hand to someone who does not trust you. Five reasons the first cannot do the second.

Your database log today

An internal record

postgres · cloudwatch · datadog

Who can edit it
Any admin with write access. Silent UPDATE, no audit on the audit.
How is it proven
Trust the operator. There is no math an outsider can run.
Where it lives
Behind your firewall. Disclosure requires legal, NDAs, and time.
Survives a breach
No. The same intruder who falsified the decision can wipe the log.
Conflict of interest
The party who acted is the party who keeps the record.

A trace.ai receipt

A public, signed record

DR-1 · merkle · base sepolia

Who can edit it
Nobody. Once anchored, the bytes are sealed by a public chain — even we cannot rewrite them.
How is it proven
Merkle proof + on-chain attestation. The math runs in the auditor’s browser, offline.
Where it lives
Public Base L2 ledger. Anyone, anywhere, with a URL.
Survives a breach
Yes. The hash is already on a chain you do not own — tampering only makes the proof fail louder.
Conflict of interest
Separate notary wallet. The record is not held by either side of the dispute.

We are not a replacement for your database. We are the layer that turns the line in your database into a receipt the outside world can verify without asking your permission.

How it works

Five steps from your AI to a public receipt. No new tools to learn.

1
Step 1Listen
When your AI agent acts, we listen.
Wrap an Anthropic or OpenAI client, or create a DR-1 record at the decision boundary with the builder.
SDK wrappers · DR-1 builder
2
Step 2Format
We give the decision a passport.
A standard, language-neutral record auditors recognize — what the AI saw, what it considered, what it picked, and why.
DR-1 schema · 12 fields
3
Step 3Bundle
Many decisions, one tamper-proof stamp.
Hundreds of records get folded into a single fingerprint. Change one byte anywhere — the fingerprint breaks.
Merkle batch
4
Step 4Anchor
Sealed with public-blockchain ink.
The bundle stamp is written to a public, neutral chain. Once it lands, no one can erase it — not even us.

Step 5Prove
Anyone can verify it. Forever.
Customers, regulators, auditors, your insurer — all hit the same public URL. Six independent checks must pass.

Real-world receipts

Pick a scenario. Watch the decision verify itself.

Bloom Co.E-COMMERCE

Refund bot approved a return.

Problem

Three months later the customer disputes the charge. The bot's reasoning is gone.

Effect

Now the full audit trail shows up in seconds — including the alternative the bot rejected.

CareGridHEALTHCARE

Triage AI sent a patient to the ER.

Problem

A miss here ends careers. Why this routing, not a video visit?

Effect

Every signal weighed, every alternative ruled out — co-signed by the attending.

Verify this decision →

ShinhanFINANCE

Fraud AI held a card charge.

Problem

The cardholder disputes the friction. The bank can't lose its work.

Effect

Hold + step-up logic, with rejected alternatives, all on a public ledger.

Positioning

What we are. What we are not.

Plaid for AI agents. Carfax for AI decisions. We sit between operators and verifiers — and never on either side.

we are

A neutral notary.

An independent attester anchors every Merkle root on a public chain. Operators can't rewrite their own logs.

we are

An integrator.

LLM client wrappers, Merkle trees, on-chain attestations. Battle-tested public goods, assembled into a new primitive.

we are

An open protocol.

DR-1 is MIT-licensed and proposed for ISO/IEC 24970. The standard is the moat — not the implementation.

we are not

Not insurance.

We don't underwrite risk. We don't pay claims. AI insurers are our customers, not our competitors.

we are not

Not custody.

We never hold customer funds. Ever. The platform attester wallet pays gas — that's the only money we touch.

we are not

Not a verdict.

We don't decide who's at fault. We make the facts cryptographically certain. Judges decide what they mean.

Pricing

Plain numbers. Both sides of the receipt.

Operators pay to anchor. Verifiers pay to check. Neither side subsidizes the other — that is what keeps us neutral.

The other side of the market

OPERATOR SIDE

The team running the AI

Pays a flat subscription to anchor.

Predictable monthly cost, regardless of how often anyone audits you.

Why subscription: you anchor on a schedule — every decision, every day. Volume is yours to forecast.

Starter · Growth · Enterprise

VERIFIER SIDE

Auditors · insurers · regulators

$0.001 per proof verification — no minimum.

Pay only when you check. A regulator who never opens a case never pays a cent.

Why consumption: verifiers cannot lock into an annual contract with a notary they may one day need to challenge in court.

Pay-per-proof API

Either side can walk away. That is the point — a receipt nobody is forced to keep is a receipt no one is forced to trust.

Competitive landscape

Adjacent, not overlapping. Three categories. One open quadrant.

The market has tooling for the AI team, dashboards for the compliance team, and insurance for the CFO. Nobody is shipping receipts the outsider can verify without permission.

Roadmap

From a single vertical, to the receipt of record.

Three phases. Each one builds the receipts the next phase rests on. No grand pivots; the schema we ship today is the schema regulators will reference in 2028.

North star

Phase 1 is what we sell today. Phase 2 is what we expand into with the receipts already anchored. Phase 3 is what regulators converge on once the schema is in production at scale.

Quickstart

One line. That's the integration.

Drop into any AI agent. We piggyback on the standard instrumentation tools you may already use; no new vocabulary to learn.

Try the verifier →Run a simulation

// pnpm add @vibingminers/sdk @anthropic-ai/sdk
import Anthropic from '@anthropic-ai/sdk';
import { traceClaude } from '@vibingminers/sdk';

// One wrap. Every messages.create now ships a receipt.
const claude = traceClaude(new Anthropic(), {
  agentId: 'cs-agent-v3',
});

const response = await claude.messages.create({
  model: 'claude-opus-4-7',
  messages: [{ role: 'user', content: prompt }],
  trace: { decisionClass: 'approve',
           rationale: 'within refund window' },
});

// → standard Anthropic response
// → receipt anchored on Base Sepolia in < 60s
// → verifier URL logged: /verify?id=<decision_id>
