Sankalp Kodandera developed the Ton Whales Vesting Deposit Transaction Builder for the BitGoJS repository, focusing on streamlining the construction and management of vesting deposits on the TON blockchain. Using TypeScript and applying principles of software architecture and unit testing, Sankalp designed the builder to align with Ton Whales workflows, improving SDK usability for developers working with TON-based vesting transactions. The work emphasized code quality and maintainability through commit-driven development, resulting in a feature that enhances productivity without introducing major bugs. Over the course of the month, Sankalp’s contributions deepened the SDK’s support for blockchain development and vesting transaction management.
