vSignal.ai Product Update - Completion of Third Cycle

Vault Ventures Plc (AQSE: VULT), a London-based technology developer focused on blockchain and AI innovation, is pleased to provide an update on the progress of its proprietary product, vSignal.ai. This announcement marks the completion of the platform's third development cycle, focused on final feature integrations, enhancing system stability, and refining the frontend in preparation for launch.

The third cycle delivered major improvements to chart functionality, interface design, and overall platform performance, with final backend and data synchronisation refinements to follow in the final development phase.

Vault remains on schedule to complete its final sprint ahead of closed user testing commencing on 29 October 2025.

Key Achievements

●    Chart data integration:
Chart data from CoinGecko is now fully implemented across all supported time ranges (1D, 7D, 1M, 3M, 1Y, and All). Both real-time updates and historical visualisations have been tested and are performing smoothly, which will provide users with fast, accurate and detailed price insights.

●    Macro Signals Framework:
The new Macro Signals Framework (which organises and explains the macroeconomic factors influencing digital asset prices) has been fully designed and integrated into the product. This system is intended to help users interpret why asset prices are moving, grouping global drivers such as inflation, interest rates, and liquidity trends into clear, actionable categories.

●    News and engagement tools:
The news feed has been stabilised, with improved reliability in fetching and displaying stories. Users will be able to interact with content via like/dislike functionality, allowing vSignal.ai to learn individual user preferences over time enabling more personalised and relevant insights.

●    Catch-up section:
The Catch-up interface has been refined to improve layout, readability, and responsiveness across all devices.

●    Chart utilities:
Users can now download or share chart images directly from within vSignal.ai, including to social media platforms, improving accessibility and engagement with visual data.

Further updates, including launch timing and shareholder access, will be provided in due course.
