Dada Shen developed and enhanced payment tokenization and processing capabilities in the KodyPay/kp-protocols-clientsdk repository over five months, focusing on secure, scalable API design and backend development. Using Protocol Buffers and gRPC, Dada unified token data contracts, standardized response structures, and consolidated token-based payment endpoints to streamline integration and improve reconciliation. The work included evolving payment data models to support richer metadata, batch processing, and FX-aware workflows, while introducing tokenization in pre-authorization flows for security. Dada also integrated new payment methods such as PAYME and Adyen tokens, demonstrating careful schema evolution, backward compatibility, and clear, maintainable commit practices.

December 2025: The KP Protocols Client SDK shipped PAYME integration and Adyen token support in the pre-authorization flow, expanding payment method coverage, strengthening security through tokenization, and setting the foundation for higher conversion and merchant satisfaction. The work is tracked across three commits to enable PAYME and Adyen token support.
