Worked on the trezor/trezor-suite repository to enhance Cardano wallet functionality by implementing DRep script ID support and improving delegation handling. Focused on updating validation and parsing logic to accommodate both legacy and CIP-aligned DRep formats, ensuring compatibility with evolving Cardano standards. Utilized TypeScript and blockchain development skills to deliver a more robust staking flow, reducing edge-case failures for users interacting with DRep scripts. The targeted changes addressed reliable DRep ID handling within wallet workflows, contributing to smoother user experiences and improved interoperability with the Cardano ecosystem. The work demonstrated depth in protocol integration and careful attention to compatibility requirements.
