Financial Services

AI Provenance for the financial services AI stack

Cryptographic provenance layer for Anthropic finance agents and any AI-generated financial output. Sign every pitch deck, IC memo, earnings note, KYC screening decision, and valuation package with three-layer timestamps designed for FRE 902(13)/(14) self-authenticating digital evidence + EU AI Act Article 50 disclosure.

Every finance-agent output is a compliance surface

Anthropic shipped 10 named agents for financial services in May 2026. Each produces output that hits a client, LP, regulator, auditor, or official record. Each carries audit + admissibility exposure that internal logging doesn't satisfy.

Anthropic agent	Output	Regulatory exposure
Pitch builder	Branded pitch decks delivered to clients	SEC/FINRA scrutiny on advertised claims
Earnings reviewer	Analyst notes published to subscribers	FINRA Rule 2241 supervisory recordkeeping
Statement auditor	LP statement reviews	Auditor + LP discovery requests
KYC screener	Document parsing + flagging decisions	BSA/AML audit trail under FinCEN exam
IC memo (PE)	Investment committee memos to LPs	Discoverable in fund-related litigation
Model builder	DCF / LBO / 3-statement Excel models	Foundation question: "did the AI build this, when, with what inputs?"
Valuation reviewer	GP package valuations for LP reporting	Independent valuation audit-able by LP advisory committee
Morning note (research)	Daily research desk distribution	Published research = FINRA-regulated; recordkeeping rules apply

What CertNode adds to your AI stack

Three primitives compose into the proof regulators and courts will accept.

Layer 1 — ES256 JWS signature

Open-standard cryptographic signature over content hash + metadata. Opposing counsel can verify independently using your published public key.

Layer 2 — RFC 3161 timestamp

Independent Time Stamp Authority countersignature. The format cited in case law for self-authenticating digital evidence under FRE 902(13)/(14).

Layer 3 — Bitcoin anchor

OpenTimestamps Merkle commitment to a Bitcoin block. Strongest non-revocable proof-of-existence. Anchored within 1–2 hours of signing.

Compliance framing

FRE 902(13) — electronic records by process

Receipts are structured to satisfy Rule 902(13) self-authentication: each is generated by deterministic cryptographic code following open standards (ES256 JWS, RFC 3161, Bitcoin OpenTimestamps). A qualified-person certification is a single paragraph; an opposing expert can run the verification independently. Designed for admissibility — no court has ruled on a CertNode receipt specifically.

FRE 902(14) — electronic records by digital signature

JWS signatures over the content hash satisfy 902(14)'s digital-signature self-authentication standard. The signed payload carries model + provider + signing timestamp + optional prompt-hash binding so the chain of custody is reproducible.

EU AI Act Article 50 disclosure

Article 50 (in force August 2026) requires AI-generated content carry machine-readable provenance. Receipt + public verify URL satisfy the cryptographic-marking requirement. EU offices using your AI outputs (and regulators auditing those offices) get the disclosure surface they need.

HIPAA-compatible patterns (for healthcare-adjacent finance)

For PHI-touching workflows: hash content client-side before signing. CertNode receives only the hash, never raw PHI. The hash binds to receipt + timestamp chain; the raw content stays in your encrypted storage under your HIPAA controls. See the privacy-preserving recipe for the implementation.

Nothing on this page is legal advice. CertNode receipts are primitives; admissibility decisions are the trier of fact's call. For high-stakes litigation, cite the underlying standards (RFC 3161, ES256, JWS) rather than the CertNode brand. Compliance teams should confirm with counsel before relying on any specific framing.

Integration path

CertNode wraps any AI agent output with a one-line signing call. Works with Anthropic finance agents, OpenAI assistants, Mistral, Llama, or in-house models — multi-model neutral. Three integration paths:

1. npm SDK (TypeScript / Node)

import { CertNode } from '@certnode/sdk'

const cert = new CertNode({ apiKey: process.env.CERTNODE_API_KEY! })
const signed = await cert.signAIOutput({
  output: pitchDeckText,
  model: 'claude-opus-4-7',
  provider: 'anthropic',
})
// signed.receiptId — store with the deliverable
// signed.verifyUrl — give to client / LP / regulator

2. REST API (any language)

curl -X POST https://certnode.io/api/v1/provenance/sign \
  -H "Authorization: Bearer $CERTNODE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"content": "...", "contentType": "document", "model": "..."}'

3. Claude plugin (Anthropic ecosystem)

For teams using Claude Cowork or Code, install the CertNode provenance plugin to add signing to any finance-agent's delivery step. See the finance-agent recipe for the wrapping pattern.
