Borja Castellano contributed to the dashpay/platform repository by enhancing wallet and SDK functionality through targeted feature development and codebase refinement. Over three months, Borja unified Rust crate dependencies at the workspace level to improve build reliability and onboarding, then focused on Swift SDK improvements, including transaction display fixes and wallet balance accuracy for the iOS app. He streamlined the Swift SDK by removing unused modules and implemented end-to-end flows for building and sending signed transactions, strengthening transaction management. Working primarily with Rust, Swift, and Docker, Borja’s work reduced maintenance overhead and improved reliability, supporting faster feature delivery and developer productivity.
April 2026 Monthly Summary for dashpay/platform: Overview: - Focused on streamlining the Swift SDK and expanding wallet capabilities to improve transaction management and reliability within the Dash ecosystem. Delivered code cleanups and functionality enhancements aligned with the platform’s goals of reducing maintenance burden and accelerating feature delivery. Key achievements (top 3-5): 1) SwiftDashSDK: Remove unused TransactionBuilder and TransactionTypes modules - Type: bug fix - Impact: Streamlined the Swift SDK by eliminating unused code paths, reducing surface area, bug surface, and maintenance effort. - Commits: 63f75a10cb03c7b41c0ed1fdaab8f1710d7ce06f (chore(swift-sdk): remove not planned to use tx module in swift-sdk (#3425)) - Notes: This cleanup minimizes dead code and potential confusion for developers integrating the SDK. 2) Swift SDK Wallet: Build and Send Signed Transactions - Type: feature - Impact: Added end-to-end capability to construct and submit signed transactions, enhancing wallet functionality and user workflows for transaction management. - Commits: 923b601da0d4f135f2bb8f9ecebf3420a2eb698a (feat(swift-sdk): send transaction (#3130)) - Notes: Co-authored-by: Borja Castellano. 3) Business value and cross-team impact - Impact: Reduced complexity in the SDK, enabling faster iteration for downstream features and improving developer productivity. Strengthened core transaction workflows in the Swift SDK Wallet to better support real-world usage scenarios and improve reliability in transaction processing. Technologies/skills demonstrated: - Swift SDK and Wallet development, including build, sign, and transmit transaction flows - Codebase cleanup and refactoring to remove unused modules - Collaboration and cross-team cooperation (Co-authored-by attribution) - Version control discipline and traceability via commit references Overall impact: - The month yielded tangible improvements in code quality and wallet capabilities, enabling faster feature delivery and lowering maintenance costs for the dashpay/platform repository.
