During March 2026, contributed to the vechain/app-hub repository by developing and integrating the Walkie DApp, a decentralized application designed to reward users’ verified physical movements with cryptocurrency. This feature expanded the App Hub’s offerings to include a lifestyle-focused, sustainability-oriented option, supporting broader user engagement within the ecosystem. The work involved creating and wiring a manifest.json file to define the application’s properties, such as name, description, and category, and adding a custom 512x512 logo. Leveraging skills in blockchain, dapp development, and web development, the contribution established a technical foundation for future growth without addressing bug fixes during this period.
