The difference
Not "Is Mr. Müller really Mr. Müller?", but "Is Mr. Müller allowed to sign a contract up to CHF 50,000 on behalf of Helvetia Treuhand AG?"
Verifiable credentials
No photocopy, no PDF: cryptographically signed credentials as SD-JWT VC (ES256) on the swiyu infrastructure, independently verifiable by any party.
Instant revocation
IETF Token Status List: verification always checks signature and status. A revocation takes effect immediately – not at the next sync.
Data-minimal by design
Only what's necessary is public. No internal identifiers, no full claims, IP addresses hashed only.
Verify without an account
Any party can verify a credential in seconds via QR code or verification link – no registration, no software installation.
Open standards
SD-JWT VC, IETF Token Status List, OID4VCI / OID4VP and did:webvh. No proprietary format, no vendor lock-in.
Integration into your systems
API keys, outgoing webhooks, a TypeScript SDK, an embeddable verification badge and SSO per organization.
Provara in action
Issue, present, verify – the full lifecycle of an authorization.
A credential as a card: person, organization, maximum amount, validity – and a public verification link.
From issuing to presenting to instant revocation – every authorization stays under your control.
The authorizations that matter in your business
Nine ready-to-use credential types – or model your own.
Right to sign
Who is allowed to sign legally binding agreements for the organization, up to what amount?
Power of attorney
Fiduciary and representation powers of attorney – granted, time-limited and revocable at any time.
Construction site access
Access and safety credentials for people on the construction site, even short-lived ones.
Supplier compliance pass
Verifiable supplier compliance status – delivered straight into your ERP via webhook.
Project role
Temporary roles and rights to act that expire automatically with the project.
Custom credential types
Model your own authorization – fields, public visibility and validity.
A controlled lifecycle
From issuance through verification to instant revocation.
Issue
Choose a credential type, enter the details, set the validity. Provara generates a cryptographically signed credential (SD-JWT VC), a QR code and a public verification link.
Present
The authorized person presents the credential as a card, QR code or link – data-minimal and limited to the required details.
Verify and revoke
Any party verifies in seconds, without an account. You stay in control and can revoke at any time – verification detects the revocation immediately.
