# 🫐 Walt.id Community Stack

Community Stack[ is an Open Source SDK from walt.id](https://walt.id/ssi-kit) which supports cheqd functionality, and other identity networks, via REST API calls or through a native CLI tool.  

## Key Features

Community Stack may be the right choice, with the following benefits

* **Open Source & Extensible**\
  Completely open-source and built for developer flexibility. Run it yourself or extend to meet your unique requirements.
* **cheqd Integration**\
  Supports `did:cheqd` for DID creation, resolution, credential issuance, and DID-Linked Resources.
* **Multi-ledger Support**\
  Use other DID methods such as `did:key`, `did:web`, `did:ebsi`, and more—across public and private networks.
* **API & CLI Interfaces**\
  Interact with the stack through easy-to-use REST APIs or a powerful CLI tool.
* **Credential Format Support**\
  Issue and verify credentials using:
  * JSON-LD (W3C Verifiable Credentials)
  * JWT-based credentials (W3C Verifiable Credentials)
  * SD-JWT-VC
  * mDL

***

### Ideal for Developers Who

* Want to experiment with identity use cases using `did:cheqd`
* Need to run identity infrastructure locally or in private cloud
* Prefer open tooling over closed-source SaaS platforms
* Are building apps that need to issue, verify, or present VCs in a standards-based way

***

### Looking for Managed Hosting?

In addition to the Community Stack, walt.id also offers a range of **SaaS identity services** for customers who need:

* Turnkey deployment
* Enterprise-grade reliability
* SLA-backed support
* Deep integration with wallet apps and verifiers

## Architecture

In order to be able to onboard the `did:cheqd` on testnet and mainnet, Community Stack relies on a [cheqd universal registrar](https://github.com/cheqd/did-registrar) deployed on walt.id infrastructure. The DID will be created using a key imported into or also created with Community Stack.
