vSignal.ai Product Update and Investor Q&A

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 follows the Company's earlier announcement of the product launch and marks the completion of the first development cycle.

The first development cycle focused on creating the foundations of the platform. Key achievements include:

·    Secure access for users: A new login and sign-up process with two-factor authentication has been completed, ensuring a safe and straightforward entry point into the platform.

·    Live market data: Real-time price feeds for leading cryptocurrencies are now integrated, giving users timely and reliable market insights.

·    Data and analytics backbone: Systems have been established to capture and process price data across multiple timeframes, supporting more detailed analysis for investors.

·    News aggregation: vSignal.ai now collates and displays daily news by asset, helping users to quickly identify relevant information that may impact markets.

·    User experience: Mobile-optimised designs have been introduced, ensuring platform accessibility for users on the move.

·    Charting tools: Interactive charts with multiple time horizons allow investors to track and interpret market trends more effectively.

Work currently underway includes completing mobile interfaces for authentication and homepage, and finalising the migration of data handling into Google Cloud Platform to support the transition from testing to live production.

The next development cycle will build on this foundation, with planned additions including:

·    AI-generated summaries of market news, providing quick, digestible insights;

·    Integration of QI's macroeconomic data, broadening the scope of analysis available to users;

·    Development of a signal module to deliver actionable indicators;

·    Completion of mobile interface, bringing the full platform experience to mobile devices.
