Alex Javabraz developed comprehensive documentation for the PowPeg App in the rsksmart/devportal repository, focusing on Flyover transactions and Peg-In modes. Using Markdown and technical writing skills, Alex clarified the differences between native and fast peg-in modes, including estimated completion times and the roles of liquidity providers. The work included updating UI instructions for hardware wallet connections and transaction mode selection, supported by revised screen images. This documentation addressed the need for clearer user guidance and technical transparency, providing depth by detailing transaction flows and user interactions. The contribution enhanced the developer portal’s usability, though it was limited to documentation improvements.
