Worked on the chainapsis/keplr-wallet repository to implement foundational support for the Noble Dollar module, focusing on establishing Protocol Buffer definitions that enable core financial operations and cross-chain capabilities. The approach centered on designing proto-level structures for transactions, queries, and genesis states, ensuring a consistent data model for future development. Refactored yield-related transaction APIs by renaming and updating proto messages to improve clarity and support evolving yield-claiming functionality. The work leveraged TypeScript, Protocol Buffers, and the Cosmos SDK, emphasizing API stabilization and cross-chain enablement. No major bugs were addressed, as efforts concentrated on groundwork for upcoming Noble Dollar features.
