Frameworks & SDKs

No one has to start implementing SSI solutions from scratch. There are many open-sourced frameworks that already cover a large portion of the standarized specifications. This page lists some of the most common SDKs and Frameworks that developers new to the space can adopt and immplement their SSI solution on it.

Aries Cloud Agent Python

Hyperledger Aries Cloud Agent Python (ACA-Py) is a foundation for building self-sovereign identity (SSI) / decentralized identity services running in non-mobile environments using DIDComm messaging, the did:peer DID method, and verifiable credentials

Aries Framework Go

Hyperledger Aries Framework Go enables trusted communication and data exchange based on interoperable distributed ledger technologies (DLTs) and peer-to-peer (P2P) interactions.

Jolocom SDK

The Jolocom SDK is a toolkit for managing SSI Agents and the interactions carried out between them, allowing services and clients to work together seamlessly with minimal trust assumptions and maximum security.

Universal Resolver

A Universal Resolver is an identifier resolver that works with any decentralized identifier system, including Decentralized Identifiers (DIDs).’s SSI Kit offers developers and organisations everything they need to use SSI via a unified solution for building use cases or applications fast and without much complexity or prior knowledge about SSI. It is based on the EU Blockchain Service Infrastructure (“EBSI”) & EU Self-Sovereign Identity Framework (“ESSIF”).


Animo works on solutions that contribute to a world where everybody has control over their own data. Using verifiable credentials we enable a new, decentralized way to store and share personal identity information that benefits everyone. Besides development work, Animo is involved in consultancy, education and the definition of standards on several levels.

Aries Framework Dotnet

Aries Framework for .NET is a comprehensive implementation of the Aries protocols. It’s purpose is to provide a universal library for building SSI application for the cloud, mobile and IoT stack.

Aries Framework Javascript

Aries Framework JavaScript is a framework for building SSI Agents and DIDComm services that aims to be compliant and interoperable with the standards defined in the Aries RFCs.
