Hyperledger Aries was moved to archived status by the project maintainers in April 2025.  While the project known as Hyperledger Aries is now being archived, its core components live on. Check out this blog post to find out where the different activities within Aries can be found now.

Hyperledger Aries is your complete toolkit for decentralized identity solutions and digital trust.

• Issue, store and present verifiable credentials with maximum privacy preservation

• Establish confidential, ongoing communication channels for rich interactions

• Meet the requirements and regulations for government-level identities

• Create wallets and agents across mobile, enterprise and the cloud

Aries is futureproofed by supporting multiple protocols, credential types, ledgers and registries. It has frameworks in multiple development languages, with interoperability tools and profiles to help everything work together seamlessly.

Key Characteristics

Privacy

• Establish decentralized credential verification and decentralized connections—give the holder more control over their information, with no “phoning home”

• Support selective disclosure, so holders only have to share the minimum amount of information

• Support Zero-Knowledge Proof (ZKP), so something can be proven (e.g. over the age of majority) without revealing the information it’s based on (e.g. date of birth)

Confidential, Ongoing Connections

• Enjoy encrypted, decentralized peer-to-peer messaging (using DIDComm) by using confidential, ongoing relationships between parties

• Support more than just issuing and presenting credentials: proactively notify holders about revoked credentials, exchange messages, and much more

Ease of deployment

• Start using ready-to-use agent frameworks in Python, Rust, Go, JavaScript and others 

• Build on multiple companion projects to get started quickly, such as Aries Mobile Agent React Native (Aries Bifold) for an open-standards smartphone wallet

Flexibility

• Leverage High-level APIs so you can easily adapt your solution in the future

• Support multiple credential types, including Hyperledger AnonCreds and W3C VCs

Community

• Leverage a well-established community with a wide range of active contributors, from individuals to large-scale organizations

Repositories, Project Management, and Issue Tracking

All Aries projects use GitHub for receiving issues, receiving pull requests and tracking releases.

*Note that while the frameworks listed below are written in a specific, identified language, for the the business layer applications built on top of the frameworks can be implemented in any language.

You can also view a list of all Aries repositories.
You can find current status of Aries Interoperability between Aries frameworks and agents here.
