Benjamin Wong contributed to the LedgerHQ/ledger-live repository by delivering user experience improvements focused on stake currency handling and account data reliability. He enhanced the stake drawer to display only whitelisted currencies and refactored the currency selection logic for better maintainability. Using React and TypeScript, Benjamin addressed issues in the Buy app by strengthening account selection and error handling when retrieving data through the getFunds Wallet API. He also improved UI component reactivity to changes in account and parentAccount identifiers, reducing the risk of stale data. His work demonstrated thoughtful attention to maintainability and data integrity in front end development.
