Project Overview

FVCP aimed to build a framework for interoperable verifiable credentials across decentralized identity (DID) ecosystems. The project enables verifiers to validate credentials issued in one jurisdiction or domain within another, using a trust registry, conversion framework, and enriched metadata to assess legitimacy while preserving security and privacy.

Methods and approaches

Cross-Domain Use Case

Credential issuance, transfer, and validation across unlinked ecosystems

Trust Registry Integration

Helps verifiers retrieve issuer metadata

Credential Conversion

Translates credentials (e.g., ZKP to SD-JWT) between ecosystems

Prototype Gateway

Developed with core components (backend, frontend, libraries)

Marel.app Integration

For end-user credential management
