Cloud Identity Wallet

Cloud Identity Wallet is a cloud-hosted, multi-tenant verifiable credential wallet designed for issuers, holders, and verifiers operating in SSI- and eIDAS-aligned ecosystems.

It implements:

• OpenID for Verifiable Credential Issuance (OpenID4VCI) for credential issuance
• OpenID for Verifiable Presentations (OpenID4VP) for credential presentation

The project is designed to support a wide range of credential formats while enabling privacy-preserving disclosure and interoperability across EUDI-compatible systems.

⚠️ Project status
This repository is under active development. Core building blocks are being implemented incrementally and APIs may change.

Key Capabilities

This project focuses on server-side wallet capabilities.

Core Wallet Features

• Multi-Tenant Architecture
  Host multiple organizations and tenants in a single instance with strong data isolation.

• Modular Design
  Pluggable components for credential formats, storage backends, and key management systems.

• Webhook & Audit Logging
  Track credential issuance and presentation events for observability and compliance.

Standards & Interoperability

• OpenID4VCI (credential issuance)
• OpenID4VP (verifiable presentations)
• Support for standardized credential formats:
  • SD-JWT
  • ISO 18013-5 (mDL / mdoc)
  • W3C Verifiable Credentials Data Model

Privacy & Security

• Privacy-preserving selective disclosure
• Encrypted storage
• Secure key management abstractions
• Designed for compliance-driven environments (eIDAS / EUDI)

Architecture Overview

A detailed breakdown of components, trust boundaries, and protocol flows is available in ARCHITECTURE.md.

Build and Test

Prerequisites

• Rust & Cargo (latest stable version)
• An optional alternative linker for faster builds (see linking guide)
