Accounts, permissions, and signing across two product surfaces.
Signavale began as a browser proof of concept with a separate mobile direction. The product needed one language for accounts, connected applications, permissions, activity, and transaction decisions.

This case study covers a real UnicornX delivery. The interface, scope, technology, and operating decisions below reflect the work completed for Signavale.
Project scope
The visible interface is one part of the delivery system.
The work combined product flows with the backend state, integrations, permissions, payments, and operating tools needed to make the experience coherent.
Connected-site permissions
Permission and activity flows gave connected applications an understandable boundary around account access.
Transaction review
Review journeys exposed recipient, asset, network fee, and total before a user approved a transaction.
Reference frame
