What is Credo?

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.
