Brandon Arbuthnot developed end-to-end SUI address support and block explorer integration for the ensdomains/ens-app-v3 repository, focusing on enhancing user onboarding and verification for SUI addresses. He implemented SUI address handling and integrated Suiscan as a block explorer, ensuring seamless compatibility with evolving address-encoder versions. Brandon expanded test coverage by adding SUI-specific scenarios to both unit and end-to-end tests, and prepared the application for localization by updating translation files. His work, primarily using JavaScript and React, strengthened the reliability and maintainability of the front end, laying a robust foundation for ongoing SUI ecosystem adoption and future maintenance.
