Over 11 months, Lisicky contributed to the MeshJS/mesh repository by engineering robust Cardano blockchain features, focusing on transaction building, governance, and asset management. Leveraging TypeScript and JavaScript, Lisicky integrated and refactored APIs, enhanced transaction serialization, and implemented deterministic sorting to ensure reliable multi-node validation. Their work included developing utilities for parsing and constructing transactions, improving witness and fee calculations, and supporting governance proposal workflows. By modernizing build configurations, managing dependencies, and strengthening test coverage, Lisicky improved maintainability and stability. The technical depth demonstrated in backend, cryptography, and smart contract integration addressed complex Cardano requirements and enabled sustainable project evolution.

2025-10 Monthly Summary: Delivered governance proposal support in Mesh SDK, fixed vote signature calculation, and updated Yoroi dependencies for 16k alignment. Focused on business value: enabling developers to construct governance transactions, ensuring vote processing correctness, and stabilizing dependency hygiene for future performance gains. Key outcomes include expanded governance action types, reliable witness calculation, and cross-repo build stability across Mesh and Yoroi.

Month: 2025-05 | MeshJS/mesh: Delivered a major sorting overhaul in MeshTxBuilder to improve determinism and reliability of transaction construction. Implemented a dedicated compareCredentials method to sort by credential type (ScriptHash before KeyHash) and then by hash, updated DRep vote sorting to prioritize script hashes, and reordered the execution sequence so sorting occurs before and after coin selection. This change, plus moving sortTxParts earlier and re-applying at the end along with queueAllLastItem and removeDuplicateInputs, yields a predictable, testable transaction assembly process. Implemented via commits: 64b44e7433e484cfdd6fd13bf3d7e0adff653a37 (fix sort order) and 8c40c288a8035086be1876b88353afbc6861c8d4 (add sort before coin selection and in the end of updateByTxPrototype).
