YubiKey Support for the Passkey Kit

SCF #40

$10.0K

Build

Awarded

Extension of the Passkey Plugin to support YubiKey hardware devices on all platforms: iOS, Android and web, plus Demo App.

Products & Services

I developed the Passkey Plugin as an open-source project to make it easy for JavaScript developers to provide multi-platform passkey functionality across iOS, Android, and Web in their Soroban dApps.

With this proposal I seek funding to extend the plugin to integrate YubiKey hardware, enabling developers to also use YubiKey as an external passkey authenticator in their Soroban dApps such as for example in Soroban Smart Wallets.

Soroban

Yes

Requested Budget

$10.0K

Success Criteria

Public open-source plugin release with YubiKey support on npm. Positive feedback from developers. Developers use the plugin and the Demo App as a reference to extend their dApps with YubiKey support.

Go-To-Market Plan

Announcement on Stellar Discord, GitHub and X platforms. Actively support users on GitHub and Discord. Collaborate with Stellar ecosystem projects and collect feedback to further improve. Provide live support and onboarding examples for developers who seek to integrate hardware passkeys.
