# Credo

## Get Started with Credo

**Credo** is a TypeScript-based framework for building Self-Sovereign Identity (SSI) agents and services. It is designed for **modularity**, **interoperability**, and **compliance** with the European Architecture and Reference Framework (ARF).

Previously known as *Aries Framework JavaScript*, Credo has recently been **rebranded** and transitioned from the **Hyperledger Foundation** to the **Open Wallet Foundation**, reflecting its broader mission and growing community.

Credo has evolved into a more flexible and general-purpose SSI framework. A major milestone in this evolution is the full **integration with** [**cheqd**](https://cheqd.io) — making Credo the first framework to support **AnonCreds on non-Indy ledgers**.

This integration showcases Credo’s expanding support for:

* Multiple **credential formats**
* Diverse **DID methods**
* Interoperable **ledger technologies**

Using Credo, developers can now issue **Verifiable Credentials**, create **Credential Schemas**, and define **Credential Definitions** using **cheqd-native AnonCreds**, enabled by the **cheqd AnonCreds Object Method**.

## Key Features

Credo may be the right choice as it has the following benefits:

* **TypeScript-native** — strongly typed, developer-friendly, and production-ready
* **Modular and extensible** — use only what you need, plug in new components
* **Cross-ledger compatibility** — supports Indy, cheqd, and beyond
* **Flexible credential support** — AnonCreds, W3C JSON-LD, JWT
* **Aligned with EU standards** — interoperable with EU ARF and continuing to align with eIDAS 2.0 implementing acts
* **Backed by the Open Wallet Foundation** — with growing community adoption

### Breaking New Ground: Credo + cheqd

Credo is now the **first framework to support AnonCreds on non-Indy ledgers**, thanks to a deep integration with [**cheqd**](https://cheqd.io). ACA-Py has since followed suit.

This includes:

* Issuance of Verifiable Credentials using cheqd DIDs
* Creation of Credential Schemas and Credential Definitions
* Support for the **cheqd AnonCreds Object Method**
* Native DID and resource support for `did:cheqd`
