Credo

Quickstart | Features | Contributing | License

Credo is a framework written in TypeScript for building decentralized identity solutions that aims to be compliant and interoperable with identity standards across the world. Credo is agnostic to any specific exchange protocol, credential format, signature suite or did method, but currently mainly focuses on alignment with OpenID4VC, DIDComm and Hyperledger Aries.

Quickstart

Documentation on how to get started with Credo can be found at https://credo.js.org/
