In February 2026, Ywt Aziz enhanced transaction management within the fireflyprotocol/pro-sdk repository by extending the BluefinProSdk class to expose transaction builder methods and a signer instance. This update, implemented in TypeScript with a focus on API design and SDK development, allowed developers to construct and sign transactions end-to-end from a unified SDK interface. By streamlining access to these components, Ywt reduced integration friction and boilerplate for downstream teams, laying groundwork for future improvements in transaction workflows. The work demonstrated a targeted, foundational approach to SDK extensibility, though the scope was limited to a single feature delivered over one month.
