Worked on the safe-global/safe-wallet-web repository to enhance reliability and data integrity for multi-network Safe deployments. Focused on refining the onboarding flow and ensuring the address book accurately reflects only valid networks, reducing inconsistency risks on the /welcome/accounts page. Utilized React and TypeScript to introduce a CreateSafeResult type, enabling explicit tracking of per-network deployment outcomes. Improved the createSafe flow to register only successful networks and filter results before updating the address book, while also refining UI and state handling for a more consistent user experience. Addressed one bug, emphasizing maintainability and robust front end development practices throughout the process.
