Sending and Receiving Credentials across interoperable Wallets

What is CHAPI?

CHAPI (Credential Handler API) is an open source protocol that allows conforming wallets to easily send and receive Credentials and Presentations to each other.
CHAPI is an open protocol designed to solve the “NASCAR Problem” - too often, users are presented with a fixed set of options for authentication with third-party sites. The CHAPI protocol provides mediation between any CHAPI-enabled web application and a third-party site. Just register your web app with your browser, and off you go!
