Is this a working wallet?+
No. This is a landing-page concept inspired by the supplied CEDAR material. The interactive panel illustrates approval counts; it cannot hold assets or sign transactions.
Does 2-of-3 mean funds can never be lost?+
No. A threshold is not an absolute safety guarantee. Implementation, signer independence, compromise, loss of access and recovery rules all affect the outcome.
Are Passkeys and a Vault the same thing?+
No. A passkey is an authentication method. A Vault approval rule determines which authorizations are required. How the two are combined depends on the actual service.
Where are the iOS app and extension?+
The supplied reference mentions web, iOS and an extension. Verified download links were not provided, so this concept offers only the browser-based demonstration.
