All You Need
We make digital identity simple.
Build end-to-end use cases or applications fast and with ease.
Store / Manage
Launch or embed ID wallets that enable users to manage identity credentials.
Wallet SDKs & APIs →
Modular Architecture
One powerful solution. Three ways to build.
We abstract the complexity of identity protocols so you don't have to.
REST APIs
Seamless Integration.
Extend any app with identity capabilities using our stateless, containerized services. We manage the heavy lifting of protocols so you can focus on your core logic.
Issuer
/onboard/issuer
/openid4vc/jwt/issue
Verifier
/openid4vc/verify
/openid4vc/policy-list
Wallet
/exchange/useOfferRequest
/exchange/usePresentationRequest
Modular SDKs
Native Performance.
Engineer custom solutions with our Kotlin Multiplatform libraries. Mix and match specific components—like Crypto or SD-JWT—to fit your exact solution.
White-Label Apps
Rapid Prototyping.
Validate ideas instantly. Use our pre-built Web Portals and PWA Wallet to test credential flows and demonstrate value without writing UI code.
Standard Compliant and Interoperable
Any Standard. Any Protocol.
Our stack is built strictly on open standards to ensure your credentials work across borders, wallets, and ecosystems.
Global Standards and Protocols
Full implementation of all major globally identity standards.
- Credential standards(W3C VC, SD-JWT VC, ISO/IEC 18013-5)
- Protocols(OID4VCI, OID4VP, Digital Credentials API)
- Crypto Algorithms(ed25519, secp256k1, secp256r1, rsa)
- Credential Status(TokenStatusList, BitStringStatusList, StatusList2021)
Regulatory Alignment
Aligned with emerging global frameworks (incl. eIDAS2), ensuring your credentials are accepted by governments and compliant wallets worldwide.
Partners And Integrations
Works With Your Infrastructure.
Seamlessly connect your existing stack and deploy anywhere with full flexibility and total data control.

FAQs
Frequently asked questions.
Answers to common questions about the Community Stack.
Are your products open source? Which license do you use?
Yes, our core products are open source under the Apache 2 license. The Enterprise Stack include features and capabilities which are not open source (e.g. multi-tenancy, data persistence, audit logs, integrations).
Do you offer support contracts?
Yes, offer support contracts for the Community Stack and the Enterprise Stack. Contact us to learn more.
Do you help with pilots or proof-of-concepts?
You can build pilots with our open source solutions or contact us if you want support from our team.
What is the difference between the Community Stack and the Enterprise Stack?
The Enterprise Stack is more stable, robust, scalable, reliable and offers additional capabilities.
- Multi-tenancy to manage multiple projects, users and accounts within them.
- Data persistence for DIDs, keys, sessions (OID4VC), logs, pre-defined issuance and verification requests.
- Resource protection through authentication for offered APIs.
- Scalability based on multi-tenancy and multiple instances.
- Pre-configured issuance and verification requests to automate processes and user flows.
- Audit & event logging (e.g. credential issuance or verification, active wallets, ...) across Issuer, Wallet and Verifiers.
- Integrations with third party services (that are not included in OSS) like ID verification, identity and access management, qualified trust services, KMS, data storage etc.
- Admin UI that facilitates the use of the Enterprise Stack and offers analytics.
The Community Stack can support production-grade solutions, yet the Enterprise Stack offers advantages like richer features and integrations, faster time to market, less overhead (dev, maintenance), more reliability and stability, higher scalability, compliance with standards and regulations.
