Mateusz Szczap contributed to the IntersectMBO/cc-ballot repository by engineering secure voting authentication with CIP-30 hashed signature support, focusing on robust payload handling and compatibility with hardware wallets. He implemented authentication flows that verify both hashed and non-hashed signatures, using Java and Kotlin to ensure reliable cryptographic verification. Mateusz also upgraded the project’s minimum JDK requirement from 17 LTS to 21 LTS, updating documentation to streamline onboarding and future maintenance. His work addressed evolving security needs in Cardano-based voting systems, reduced technical debt, and positioned the codebase for broader CIP-30 adoption and integration with modern Java libraries.

January 2025 focused on future-proofing the IntersectMBO/cc-ballot codebase by upgrading the minimum JDK to 21 LTS and updating internal documentation to reflect the change. This aligns the project with modern Java features and upcoming library requirements, reducing technical debt and easing future maintenance. The change was implemented via commit 4d4e83f833e535bb4b74ddbeb161fe8d5c4ad90b and reflected in README.md to ensure clear onboarding for developers.
