Identity Toolkit / Platform Attributes
Origins Identity / Developer tools (created to make SSI/VC implementation accessible to developers; tooling-first approach)
Database Pluggable (supports multiple storage backends; wallet data in local/cloud storage depending on deployment)
Query Language REST API (comprehensive APIs for credential lifecycle management, DID operations, wallet management)
Data Formats W3C Verifiable Credentials (VCDM 1.1 / 2.0) + SD-JWT VC + ISO/IEC 18013-5 (mDL/mdocs) + ERC-721 (NFTs) + JSON-LD + JWT
Mobile Support Mobile support (native iOS and Android SDKs introduced 2024; white-label wallet app)
Web Support Yes (web-based wallet, claim pages, and verifier portal; white-label web components)
Native Apps Mobile wallet apps (white-label for iOS/Android); desktop via web
Terms Self-hosting + Licensed install (Community Stack: free open-source; Enterprise Stack: commercial license with SLA)
Funds Undisclosed (bootstrapped to revenue; no publicly disclosed VC rounds)
Based On W3C DID and VC standards; OpenID for Verifiable Credentials (OID4VC); ISO/IEC 18013-5/-7; SD-JWT; eIDAS 2.0 / EUDI Wallet ARF; ERC-721
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
Identity Standards - List
DID Methods Supported did:web, did:key, did:jwk, did:ebsi, did:cheqd, and others (multi-method support; ecosystem-specific methods)
DID Methods Supported - List
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
Credential Types - List
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
Credential Exchange Protocols - List
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)
