Integrating an EUDI Wallet with the W3C Digital Credentials API involves using the DC API flow and CTAP-Hybrid to enable secure cross-device and same-device remote presentation of digital credentials through browser integration.

Wallet selection and origin verification during digital credential issuance work by defining specific invocation mechanisms and session binding requirements, ensuring browsers and operating systems correctly route requests to the correct wallet while maintaining technological neutrality and privacy.

Security considerations for cross-device flows in the W3C Digital Credentials API require addressing origin verification, session binding, and secure invocation mechanisms to protect user privacy and ensure safe remote presentation across different devices and browsers.

Yes, the W3C Digital Credentials API supports both same-device and cross-device wallet integration, detailing specific responsibilities and implementation requirements for browsers and operating systems to handle secure remote presentation and issuance flows effectively.

Responsibilities of browsers and operating systems when implementing the DC API flow include managing wallet selection, handling secure invocation mechanisms, enforcing origin verification, and maintaining session binding to ensure availability, privacy, and functional expectations during credential exchanges.
