Anastasis developed a controlled rollout for the Flexible Multisig Wallet feature in the novasamatech/nova-spektr repository, focusing on frontend development with React, JavaScript, and TypeScript. The implementation involved hiding the new wallet flow by default and enabling it only in development environments, reducing production risk and supporting staged deployments. Anastasis also refined the back navigation logic to prevent users from exiting the modal when the feature was inactive, improving user experience during rollout. The work emphasized environment-based feature gating, UI state management, and strong commit traceability, laying a solid foundation for safer releases and more effective collaboration with product and QA teams.
