("Vault Ventures" or the "Company")

vSignal.ai Product Update

Vault Ventures Plc (AQSE: VULT), a London-based technology developer focused on blockchain and AI innovation, is pleased to provide an update on the development of its proprietary product, vSignal.ai. This announcement marks the completion of the platform's second development cycle.

The goal of this cycle was to bring together all major components of the platform into a fully integrated and operational system in preparation for deployment.

Key Achievements

·      Infrastructure ready for scale: vSignal.ai is now live across its full cloud environment, providing a secure and scalable foundation, a key preparatory step as the product moves towards launch.

·      Seamless user access: Secure login and sign-up processes, including Google and email authentication with verification, are now fully operational.

·      Dynamic content experience: The homepage now supports different content or features depending on a user's access level, allowing the Company to control who sees what during testing.

·      AI-driven insight engine: Live news and data feeds are powered by CryptoPanic and Gemini AI, which automatically summarises and prioritises market updates for users.

·      Contextual signal generation: Perplexity AI has been integrated to surface relevant news based on macroeconomic data trends, helping users understand why key indicators are moving and delivering early trading and investment signals.

·      Comprehensive data coverage: Historical and live macroeconomic and cryptocurrency data are now fully integrated, supporting deeper, context-rich analysis.

·      Smarter user interface: Updated layouts, modals and interactive components improve navigation and data visibility, particularly on mobile devices.

Next Goals
With over 95% of backend functionality complete, the next phase will focus on final product polish and expansion. The development team is improving the sign-on experience by adding guidance for choosing coins and making visuals more attractive. Charting tools are being upgraded to support custom date ranges, and refinements to the user interface and user experience are under way to optimise responsiveness and visual design.

Our final development sprint starts next week ahead of closed user testing which starts on the 29th October. In the coming weeks we'll be in a position to finalise launch timings, including when shareholders will get first access.
