Kit de Herramientas / Plataforma de Identidad Atributos
Orígenes Identity / Web3 authentication (won Ethereum Foundation + ENS RFP to develop Sign-In with Ethereum standard; expanded to government-grade credential issuance)
Base de Datos Kepler (decentralized storage network organized around data overlays called Orbits; user-controlled encrypted storage via Web3 wallets) + credential-specific storage per deployment
Lenguaje de Consulta REST API + GraphQL (SpruceKit and Credible Platform expose REST APIs; DIDKit provides programmatic access)

Soporte Móvil Mobile support (SpruceKit Wallet SDK supports React Native, Flutter, and native iOS/Android; built CA DMV Wallet app with 4.8-star ratings on both app stores)
Soporte Web Yes (SIWE enables web browser authentication via Ethereum wallets; SpruceKit provides web-based credential management; OIDC Identity Provider for SIWE)
Aplicaciones Nativas Native apps (California DMV Wallet for iOS and Android; SpruceKit Wallet SDK enables native app development)
Términos Self-hosting + Enterprise SaaS (open-source libraries for self-hosting; Credible Platform available as cloud-prem or on-prem enterprise deployment)
Fondos $34M Series A (a16z crypto lead; participants include Ethereal Ventures, Electric Capital, Y Combinator, Okta Ventures, SCB 10X, Robot Ventures, OrangeDAO)

Permisos Apache 2.0 / MIT (dual, permissive) — SpruceKit and all component libraries are published under Apache 2.0 or MIT licenses, allowing use in commercial and proprietary products without source disclosure. Contributors provide an express patent grant under Apache 2.0.
Herramientas de Desarrollo SpruceKit SDK (open source, Apache 2.0 / MIT) — modular Rust, Swift, Kotlin, and TypeScript libraries for W3C VC issuance/verification, mDL (ISO 18013-5), and selective disclosure; ssi Rust core library (Apache 2.0) for DID resolution and cryptographic signing; SpruceKit Mobile SDK for iOS/Android credential wallet integration; SIWE (Sign-In with Ethereum) libraries in JavaScript, Rust, and Python; OpenID4VP Rust implementation; archived DIDKit cross-platform CLI and language bindings (Rust, Python, Java, Flutter); Credible reference wallet (Flutter, archived); TreeLDR schema definition language; Swagger/OpenAPI docs at sprucekit.dev.
Autenticación e Identidad Decentralized ID (DID) with multiple methods; Sign-In with Ethereum (SIWE/EIP-4361) as primary Web3 authentication; OIDC Identity Provider bridge for Web2 integration; wallet-based authentication
Modelo de Almacenamiento Kepler (decentralized storage with user-controlled Orbits); credential storage in holder wallets; issuer-side credential management via Credible Platform (cloud-prem or on-prem)
Interoperabilidad High: W3C VC + ISO mDL dual-format support; OIDC/SIWE bridge for Web2; interoperability demonstrated with 25+ vendors; working with AAMVA, NIST, Google, Panasonic, Samsung, Okta, Auth0; TSA mDL acceptance
Portabilidad de Datos Full portability (W3C VC and ISO mDL standards-based credentials; open-source wallet SDK; no platform lock-in; CA DMV Wallet supports Apple and Android native wallets as alternatives)
Gobernanza y Toma de Decisiones Company-controlled (Spruce Systems Inc.) with strong open-standards commitment; SIWE developed via open community calls with Ethereum Foundation and ENS; active W3C, DIF, and standards body participation
Estándares de Identidad W3C DID; W3C Verifiable Credentials (VCDM 1.1 and 2.0); EIP-4361 (SIWE); ISO/IEC 18013-5 (mDL); OpenID Connect; OIDC4VC; DID method traits specification
Métodos DID Soportados did:key, did:web, did:pkh (blockchain-agnostic), did:ens, did:ethr, did:ion, did:tz (Tezos); DID method traits spec for upgradeable identity paths
Gestión de Claves User-controlled (wallet-based key management); HSM support for enterprise (Credible Platform supports hardware security modules); TEE support (trusted execution environments); browser/OS keychain integration
Tipos de Credenciales Verifiable Credentials (W3C VCDM); mobile driver's licenses (ISO mDL); SD-JWT VCs; professional/educational credentials; age verification credentials; government IDs; Rebase witnesses for social account linking
Método de Verificación Cryptographic signature verification (multiple suites including Ed25519, EcdsaSecp256k1, BBS+); on-device verification (mDL NFC/QR without callback to issuer); selective disclosure; Groth16 ZKP support
Funciones de Privacidad Selective disclosure (mDL: share only required fields, e.g., age >21 without address); no digital trail/phone-home by design; on-device verification; privacy-preserving credential presentation
Métodos de Autenticación Cryptographic signatures (wallet-based); Sign-In with Ethereum (EIP-4361); OIDC via SIWE Identity Provider; biometric authentication (device-level for mDL); passkeys/WebAuthn compatibility
