Digital Evidence Infrastructure

Proof > Signature

Most digital workflows don't require a qualified signature. They require verifiable, cryptographic evidence.

Register the integrity of your agreements, consents and acceptance flows using cryptographic proofs — without storing files, reducing friction, and without the overhead of complex signing workflows.

Built for developers. Stateless REST API. Zero-Storage.

How It Works in 3 Steps

Simple technical integration for critical onboarding flows.

1

Client-Side Hashing

Your system generates the document hash (content integrity) on the client. File content is never transmitted.

2

Trust Event API

You send the hash to our REST endpoint. Veltia seals the event with a cryptographically trusted timestamp.

3

JWS Receipt

You receive an immutable signed JWS receipt. It is stored in your own database for future auditing (self-custody).

The 14 Axioms of Veltia

An architecture designed for absolute privacy and radical regulatory compliance.

🛡️

Zero-Storage Architecture (Axiom 1)

We never store your files or PII. We only register and verify cryptographic evidence. Veltia never needs to recover customer data because it never stores it.

📱

Content Integrity

Client-side hashing using cryptographic salts. Ensures the document footprint is unique and unforgeable without exposing the original contents.

⚡

eIDAS Trust Levels

Scale evidence compliance levels from cryptographic timestamps to native EUDI Wallet verification, without changing your integration code.

Why switch from signature-based workflows

No document uploads
No signature friction
No per-signature costs
No vendor lock-in
No compliance overhead
