Worked on the Near-One/mpc repository to enhance the cryptographic signature provider by refactoring its threshold handling. Focused on backend development using Rust, the work introduced explicit, type-safe threshold types to the cryptographic module, ensuring stronger compile-time guarantees and improving both safety and maintainability in multi-party computation scenarios. This approach clarified threshold logic and reduced the risk of runtime errors, contributing to more robust cryptographic operations. The changes were carefully documented and linked to a specific commit for traceability, supporting collaborative development practices. No bugs were fixed during this period, with efforts concentrated on feature development and technical refinement.
