Andrii Onyshchenko focused on stabilizing the rune transfer flow in the omnisat/lasereyes-mono repository, addressing a critical bug that previously caused change from rune transfers to be misrouted to the sender’s address instead of the designated payment address. Using TypeScript and full stack development skills, Andrii implemented a fix that ensures change is now correctly returned to the intended recipient, thereby improving settlement accuracy and reducing support overhead. The solution was thoroughly documented and prepared for cross-environment testing, laying the groundwork for future enhancements in transfer-flow reliability and quality assurance. This work deepened the robustness of the project’s transaction logic.
