The client faces complexities in creating a secure, transparent, and user-friendly stock exchange leveraging blockchain technology. Existing platforms lack comprehensive blockchain support, seamless UI for both novice and experienced traders, and scalable infrastructure to handle high transaction volumes. Additionally, ensuring transaction safety, user self-custody of securities, and compliance with regulatory standards present significant technical and operational challenges.

A technology-driven financial institution aiming to innovate in securities trading through blockchain technology, targeting both traditional and decentralized finance markets.

• Implement features allowing users to settle trades in stablecoins (e.g., USDC) and withdraw securities to their blockchain wallets for self-custody.
• Create an intuitive UI/UX that balances accessibility for newcomers with depth for experienced traders.
• Build a consistent visual language and branding for the platform.
• Develop a comprehensive service blueprint, including user journeys, backend processes, and security protocols.
• Ensure platform infrastructure supports scalability, high availability, and compliance with security best practices.
• Utilize and integrate modern technologies such as React.js for frontend, Python for backend, and AWS cloud services.

• User registration and authentication with KYC/AML compliance mechanisms.
