Independent Evidence Infrastructure · eIDAS-ready

Make your documents provable,
even outside your system.

eIDAS-ready evidence rails with independent timestamps, anchored proofs, verification APIs, and exportable dossiers — packaged as Stripe-metered product economics, not a PDF button.

Even if operators lose trust in your control plane — you ship artefacts that reconcile outside it.

Infrastructure positioning — not a feature tagline pasted into UX chrome.

Product stack

Three planes — engineered as one billable continuity.

Core

Integrity & proof surface

  • Cryptographic hash lineage
  • Verification API & public proof patterns
  • Append-friendly audit chronology

Trust layer

PAdES-aligned signing

  • Provider-orchestrated PAdES (QTSP integrations)
  • OCSP / CRL & LTV posture documented
  • Visible signature presentation where required

See also EUDI & signature programme.

Premium wedge

External notarisation

  • RFC 3161 TSA timestamps (where engaged)
  • Public anchors (ledger selection per procurement)
  • Evidence ZIP / manifest exporters
  • Verification decoupled from your admin DB narratives

Technical scope — which TSA, which anchor, retention — fixed in SoW.

Problem

Your documents are only trusted if your perimeter is trusted.

What happens when a document is challenged in court — or rejected in tender diligence?

Solution

Anchor evidence outside primary SaaS narratives.

Control-plane stays yours — artefacts become inspectable downstream.

Document → Hash → Signature (PAdES) → RFC 3161 timestamp → Anchor (ledger) → Exportable dossier → Verify URI
Symbolic pipeline — sequencing and cryptographic binding depend on contractual profile (SES / AES / QES-grade paths).

What you get

Not “a PDF signer”. A stack buyers can scrutinise.

PAdES-shaped PDFs — via accredited provider orchestration.
Independent timestamps — RFC 3161 TSA tokens when contracted.
Public anchors — hash commitments verifiable beyond your infra.
Evidence packages — dispute & audit-oriented folder exports.
