The document discusses improving the developer experience for self-sovereign identity (SSI). It introduces Streetcred ID, a platform that enables organizations and individuals to exchange secure digital credentials. Streetcred ID's tools allow organizations to integrate decentralized identity into existing systems and issue verifiable credentials to users, who can then prove claims about themselves to other parties. An example is given of a user seamlessly providing proof of identity attributes to a landlord using Streetcred ID.
