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
