One platform, five components. Choose the components that fit your institution — or combine them.
The Universal STAMP® App is designed for power users and high-volume guarantors who need speed, batch processing, and offline capability. Run directly on Windows workstations with native performance.
Ideal for institutions issuing large numbers of guarantees daily. The Universal STAMP® App handles batch operations efficiently with an intuitive interface built for professional workflows.
LWS is the browser-based interface for guarantors and transfer agents. It requires no client software and works on any device, making it the fastest path to offering digital Medallion Signature Guarantees to your team.
Because LWS runs in the browser, IT overhead is minimal. Updates are delivered automatically. Your team is always on the latest version.
WebHub is the web-based administration portal for your U-STAMP® account. It gives administrators complete control over every aspect of the platform: who can sign, what gets stamped, and how the account is configured.
WebHub runs in any modern browser and is the central hub for compliance officers, account administrators, and operations managers who need visibility and control without using the signing tools directly.
The Validation Server is a headless background service that automatically validates incoming U-STAMP® signed documents without manual intervention. Configure it to watch a folder or accept HTTP POST uploads — it validates signatures, routes results, and generates a full audit trail for every document.
Designed for high-volume Transfer Agents who need continuous, unattended document validation integrated directly into their existing processing pipeline.
The Universal STAMP® REST API is built for system-to-system integration. Automate Medallion workflows end-to-end, from order receipt to signed document delivery, without manual intervention.
Choose how your staff accesses the platform.
The core platform is hosted and managed by the U-STAMP® platform provider. No server infrastructure to run or maintain. Automatic updates, high availability, and enterprise-grade security are built in.
Combined with your choice of client-side access:
Deploy a lightweight web server within your own data center. Transactions are processed entirely within your secured network. The back-end is contacted only for user verification and transaction logging.
Install the Universal STAMP® App directly on staff workstations. Also compatible with Virtual Desktop Infrastructure (VDI) environments for centralized deployment and management across your organization.
