Mateusz Domanski contributed to LedgerHQ/ledger-live by engineering end-to-end Hedera blockchain support, including staking, token association, ERC20 integration, and transaction processing. He architected robust backend and frontend flows using TypeScript, React, and Node.js, focusing on modular coin support and reliable data retrieval. His work included modernizing transaction serialization, implementing comprehensive integration and unit tests, and enhancing UI/UX for both desktop and mobile. By refactoring core modules and strengthening validation, he improved maintainability and reduced risk of regression. Mateusz’s approach emphasized production readiness, compatibility enforcement, and localization, resulting in broader asset coverage and a more resilient Hedera integration.

November 2025 Monthly Summary for Ledger Live (LedgerHQ/ledger-live). Focused on expanding Hedera network capabilities and reinforcing app safety. Key deliveries include Hedera staking support with delegation and rewards UI, Hedera ERC20 token support in the coin-hedera module (transfers, fee estimation, EVM address verification alerts), enforcement of minimum Hedera app version (initially 1.8.5, later updated to 1.9.0) to ensure compatibility, retrieval of Hedera getBlock data (with transactions and tests), and UI localization improvements using the useLocalizedUrl hook. These changes broaden supported assets, improve reliability, and enable more accurate data flows, delivering direct business value through safer updates, richer asset support, and improved localization.
