Walt.id
Identity Platforms/FrameworksAll-in-one open-source identity and wallet infrastructure toolkit for developers, governments, and enterprises. Provides modular libraries, APIs, and white-label apps covering the full credential lifecycle across 10+ identity ecosystems and all major credential standards (W3C VC, SD-JWT VC, ISO mDL/mdocs, ERC-721). Community Stack (open-source) and Enterprise Stack (licensed) serve five-digit user base including Oracle and government clients.

Identity Toolkit / Platform Attributes
Permissions Apache 2.0 (Community Stack, open source) / Proprietary (Enterprise Stack) — The Community Stack (waltid-identity monorepo and all core libraries) is published under Apache 2.0: permissive, commercial use allowed, patent grant included, no copyleft. The Enterprise Stack and Cloud Platform include features not released as open source. Dual-track model allows free community use with optional paid enterprise support and SLAs.
Development Tools waltid-identity monorepo (Apache 2.0, open source) — multiplatform Kotlin/JavaScript/iOS library suite covering: Core Libs (Crypto key management with AWS/Hashicorp/OCI KMS backends, DID resolution/registration, SD-JWT, OIDC4VC, JSON-LD); Credential Libs (W3C VC as JWT/SD-JWT, mdoc/mDL ISO 18013-5); Ecosystem Libs (EBSI, cheqd, eIDAS2, IOTA trust registries). REST APIs (Issuer, Verifier, Holder) deployable via Docker. Web-Wallet PWA (white-label, custodial). waltid-examples Kotlin/Java SDK tutorial project. Maven repository at maven.waltid.dev. Discord community and GitHub Discussions. Enterprise Stack adds features not in Community Stack (closed source).
Authentication & Identity Decentralized ID (DID) with multi-ecosystem support; OIDC integration; SIOPv2 (Self-Issued OpenID Provider); NFT-based authentication
Storage Model Hybrid (local wallet storage + cloud deployment options; enterprise can deploy on-prem or cloud)
Interoperability High: 10+ identity ecosystems supported; interoperability with 25+ vendors demonstrated at plug fests; EUDI Wallet ARF alignment; supports W3C VC, SD-JWT VC, ISO mDL, and NFT standards simultaneously
Data Portability Full export (standards-based credentials in W3C VC, SD-JWT, ISO mDL formats; no proprietary format lock-in)
Governance & Decision Making Company-controlled (walt.id GmbH); active standards body participation (W3C, IETF, OIDF, DIF)
Identity Standards W3C DID; W3C Verifiable Credentials (VCDM 2.0); SD-JWT VC; ISO/IEC 18013-5 (mDL); ISO/IEC 18013-7; OpenID4VC; SIOPv2; eIDAS 2.0
DID Methods Supported did:web, did:key, did:jwk, did:ebsi, did:cheqd, and others (multi-method support; ecosystem-specific methods)
Key Management User-controlled (wallet-based); enterprise key management; pluggable KMS architecture
Credential Types Verifiable Credentials (W3C VCDM); SD-JWT VCs; ISO mDL/mdocs; ERC-721 NFTs; educational credentials; professional certifications; government IDs
Verification Method Cryptographic signature verification (multi-algorithm support); SD-JWT selective disclosure verification; mDL device authentication
Privacy Features Selective disclosure (SD-JWT VC); ZK presentations (via supported credential formats); data minimization
Authentication Methods Cryptographic signatures; OIDC/SIOPv2; NFT ownership verification; QR code scanning; deep linking
Revocation Mechanism StatusList2021; credential expiration; issuer revocation via supported standards
Agent Types Supported Humans (individuals); Organizations (enterprise issuers/verifiers); NFT holders
Wallet/Client Types Mobile app (white-label wallet for iOS/Android); web-based wallet; SDK/Library integration (Kotlin, TypeScript); CLI tools
Recovery Mechanisms Wallet-dependent (device backup, cloud sync depending on deployment)
Compliance / Regulations eIDAS 2.0 compliant (EUDI Wallet ARF alignment); GDPR compliant; ISO/IEC 18013 series compliance
Credential Exchange Protocols OIDC4VC (OpenID for Verifiable Credentials — OID4VCI, OID4VP); Presentation Exchange; DIDComm; ISO mDL presentation protocols
Trust Framework Cryptographic verification; trusted issuer registries; standards-based trust (eIDAS, EUDI)
Cost Model Free (Community Stack, Apache 2.0) + Enterprise licensing (Enterprise Stack with SLA and support contracts)
Censorship Resistance Depends on DID method (decentralized credentials are portable; platform availability depends on walt.id infrastructure for Enterprise Stack)
