Apr 1, 2026April 2026 (wwWallet/wallet-frontend): Delivered security and interoperability enhancements across credential flows. Implemented negotiation of credential response encryption algorithms, standardized ECDH-ES usage via a named constant, hardened encrypted response header processing, and introduced a wallet-supported algorithm list with issuer-alg validation to improve interoperability with issuers. These changes reduce edge-case failures, strengthen security posture, and accelerate partner integrations.

Mar 1, 2026March 2026 focused on strengthening reliability, onboarding UX, PWA engagement, and branding consistency for wwWallet/wallet-frontend. Key OpenID4VP flow improvements hardened the authentication path to gracefully handle non-200 responses and 3xx redirects, reducing auth-related failures and improving interoperability with identity providers. Signup/login UX enhancements delivered clearer onboarding, Passkey information UI, simplified login rendering, and branding/config refinements to help users progress faster. PWA install prompt UX was restored and made configurable via environment flags, improving discoverability and user retention on first login. Branding was standardized by hard-coding the Powered by statement for consistent messaging across the app. Overall impact includes higher reliability of auth flows, improved first-time user experience, and a more predictable branding/prompt behavior, supported by targeted code cleanups and refactors.
