Your credentials. Your app.
Your wallet or ours.
Embed multi-format credential wallet capabilities into your existing iOS or Android app with our Mobile SDK, or deploy Holdr+, our white-label wallet, for immediate use. Every major credential format and protocol, all the code in one place.
Two ways to deploy
One wallet platform. Two integration paths
Both paths run on one codebase and deliver the same multi-format, multi-protocol interoperability. Pick the one that fits your product and timeline.
Embed
Mobile SDK
Drop full wallet capability into the app you already ship. Users never leave your brand. Keys and credentials stay on the device.
Deploy
White-Label App
Holdr+ is a finished wallet app, branded as yours. Ship it without building from scratch. Best for fast time-to-market, or a standalone user experience.
Under the hood
Every major format, protocol, and method
The Proven wallet handles presentation logic on the user’s behalf, so people move across credential formats, jurisdictions, and sectors without friction.

Learn more →Reusable KYC
Verify a customer once, then reuse that identity across products, channels, and partners. Less onboarding friction, lower compliance cost.
Learn more →Workforce & Access
Issue employee and contractor credentials that work across systems, roles, and organizations. No manual re-provisioning. No shared passwords.
Learn more →Customer Authentication
Replace passwords and security questions with Verifiable Credentials. Customers authenticate and recover accounts instantly. Synthetic IDs and AI-driven fraud are shut out.
Learn more →Verified Attributes & Loyalty
Personalized experiences and loyalty perks from attributes customers consent to share. No personal data exposed.
Learn more →User experience
Credential exchange that feels like a conversation
Credential exchange happens in a familiar chat-style interface. Requests, presentations, and approvals arrive as plain-language messages.
Contextual requests
Each request explains what’s being asked, why, and by whom. Tap to approve or decline.
One flow, any format
The same conversation handles every credential type. The person never needs to know which format is in play.
FAQ
Questions, answered
Does it work with Apple, Google, and EUDI wallets?
Yes, in both directions. Indicio’s verifier accepts credentials from Apple, Google, EUDI, and any standards-compliant wallet. The Indicio wallet presents to any compliant verifier. Your users aren’t locked to one ecosystem, and your verifiers aren’t limited to one issuer.
Where is credential data stored, and who controls it?
On the holder’s device, in a biometric-protected wallet. Data moves only with explicit consent, and selective disclosure lets a verifier receive only what they need. After issuance, neither Indicio nor the issuer can see the credential data.
Does verification call back to the issuer?
No. The proof is embedded in the credential. The verifier checks the signature, confirms the issuer is in the trust registry, and detects any tampering, all locally and instantly. No issuer callback, no central database.
Can credentials work offline?
Yes. Because that proof is self-contained, no network is needed to verify it: in-person presentation runs over BLE and NFC with no connection at all. That matters at border crossings, remote sites, and anywhere connectivity is unreliable.
What platforms and languages does the SDK support?
Kotlin, Swift, React Native, and Flutter, covering iOS and Android. It ships localized in eight languages out of the box (English, Spanish, French, German, Italian, Portuguese, Japanese, Arabic), with more on request.
