Customer Challenges

Our client, a rapidly growing fintech startup in South Africa, aimed to create a secure and reliable crypto exchange platform to facilitate trading in multiple cryptocurrencies for retail and institutional investors. The challenges they faced included:

Lack of a secure, fully compliant crypto trading platform supporting fiat-to-crypto transactions

Dependency on third-party wallets and APIs, leading to delays and higher operational risk.

Need for KYC and AML compliance for user onboarding in line with South African regulations.

Scalability and real-time transaction processing for high-volume trading scenarios.

Providing a mobile-first experience without compromising security and performance

Integration of wallet management, trading, and transaction history in one seamless platform.

The client required a robust, end-to-end solution that would handle trading, wallet management, and transaction verification without third-party dependencies.
