Services
This ecosystem includes the following services. Connect to any of them using Hologram Messaging.
Organization
Trust AnchorThe root of trust for this ecosystem. It registers with the Verana Network as a verified organization, creates a Trust Registry with a custom credential schema, and issues Service credentials to child services. All other services in this ecosystem derive their trust from this anchor.
This is the trust anchor — it has no public-facing chatbot. It operates in the background, issuing credentials to the services below.
Avatar
Credential Issuer ChatbotA DIDComm chatbot that issues verifiable credentials to users through conversational interactions. Connect with Hologram Messaging, follow the guided flow, and receive a W3C Verifiable Credential backed by the Verana Trust Registry. Your credential proves attributes about you and can be verified by any party.
GitHub Agent
AI Agent with MCPAn AI-powered GitHub assistant that uses the Model Context Protocol (MCP) to interact with GitHub on your behalf. Search repositories, browse issues and pull requests, explore code, and manage your projects — all through an encrypted DIDComm chat in Hologram Messaging. To get started: first authenticate using the credential you received from the Avatar service, then open the contextual menu, select "MCP Server Config", and enter your GitHub Personal Access Token. Once configured, the agent can access GitHub tools on your behalf.
How to use
To interact with any service in this ecosystem you need Hologram Messaging — a mobile wallet that manages your credentials and DIDComm connections.
Install Hologram Messaging
Download the mobile wallet app. It stores your credentials and communicates with services using DIDComm — an encrypted, peer-to-peer messaging protocol.
Connect to a service
Tap "Show QR Code" on any service card below, then scan it with Hologram Messaging to establish an encrypted DIDComm connection.
Interact via chat
The service appears as a contact in Hologram. Chat with it to receive credentials, ask questions, or interact with AI agents — all encrypted end-to-end.
Repository
Each service has its own directory with deployment configuration, Docker Compose for local development, and a GitHub Actions workflow for CI/CD.
