May 2025 monthly summary for worldfnd/provekit focused on aligning documentation with the updated project structure to improve onboarding, reduce user errors, and streamline contributor workflows. The effort centers on ensuring that README paths match the current directory layout so build and proof-generation commands are accurate for users following the documentation.

April 2025 monthly summary focusing on key accomplishments across kkrt-labs/keth and starkware-libs/stwo, emphasizing reliability, maintainability, and business value. Delivered test robustness, project structure standardization, tooling refinements, and CI/CD improvements that reduce risk and accelerate releases.

March 2025 monthly summary: Delivered feature-rich enhancements across kkrt-labs/keth and starkware-libs/stwo-cairo, focusing on visibility, automation, robustness, and external-service readiness. Highlights include a Codecov badge for visibility, automated Ethereum block testing scripts, robust contract-code fetch during zkpi_to_eels state conversion, and CI/Dev configuration improvements for external tooling, plus user guidance updates in documentation to reduce setup friction. No major bugs reported; efforts focused on preventing issues through tooling and robustness improvements.

February 2025 monthly summary for kkrt-labs/keth: Delivered robust elliptic-curve cryptography primitives in Cairo (ec_add, ec_double) with on-curve verification and quadratic-residue checks, enabling secure on-chain ECC operations and tests. Fixed a critical off-by-one error in jumpdest validation to ensure correct bytecode jump destination checks, improving runtime safety. Enhanced ZKPi-to-EELS fixture handling for more reliable Ethereum transaction processing. Boosted test coverage and CI visibility by integrating Codecov, adding coverage fixtures, and refining reporting. Advanced Cairo VM profiling with an execution-trace DataFrame view and corrected recursive step calculations, alongside dependency/tooling updates (Cairo VM, isort alignment, runtime flags) for smoother development and deployment. Performed Keth project cleanup and refactor to simplify repository structure and reduce debt, including removal of unused Cairo programs. These actions improved security, reliability, and developer productivity, enabling faster, safer releases and better measurable quality." ,
