In March 2026, delivered cross-platform Concordium support in Ledger Live by migrating from gRPC to wallet-proxy REST, enabling web environments and achieving broader cross-platform compatibility. Introduced wallet-proxy data endpoints for consensus and block information, and extended responses with blockHeight to account transactions for precise block-context in the UI. Implemented user-facing enhancements including a new Concordium receive confirmation screen (QR, copy/share, address verification) and memo tag input with validation for send flows. Strengthened onboarding reliability with shared error types and added WalletConnect onboarding and 2FA tests, improving error handling and test coverage. Added Sui testnet support and testnet currencies, expanding multi-chain/testnet capabilities. Completed core API and module architecture improvements, decoupling the Concordium module from CryptoCurrency and refining API/network layer signatures, along with staking event handling improvements for better operational visibility. These outcomes reduce dependency on node-specific gRPC, improve data accuracy and reliability, and accelerate feature delivery with clearer cross-repo ownership and test coverage.

February 2026 LedgerHQ/ledger-live monthly summary: Delivered Concordium Transaction Serialization Enhancement with Memo Encoding. Implemented custom serialization methods for Concordium transactions, including support for memo encoding, covering transfer and credential deployment flows. Commit 22a7682dba09db84f80fbb08918b8da6804bfbf1: feat(concordium): added custom transaction serialization methods to hw-app-concordium. Impact: improved reliability and interoperability for Concordium transactions in Ledger Live, enabling memo-based workflows and reducing reconciliation effort.

January 2026: Delivered initial Concordium hardware wallet integration (hw-app-concordium) for Ledger Live and completed a validation-focused refactor. Implemented address retrieval, transaction signing, and credential deployment; followed by a refactor that relocates the SchemeId enum, adds runtime validation for year/month serialization, and exposes transport for testing. These changes extend Ledger Live hardware wallet support, improve security and reliability, and lay groundwork for broader QA/testing and future Concordium feature work.

Month: 2025-12 Concise monthly summary for Ledger Live development: This period focused on expanding asset coverage and improving developer tooling. Delivered Concordium coin module integration, including API setup, transaction handling, and integration with existing Ledger frameworks, with support for Concordium’s abandon seed address. Implemented linting optimization for the build directory to streamline CI, by adding a .eslintignore to skip build/ checks for the mobile performance test workflow. No major bugs fixed this month; the emphasis was on feature delivery and tooling improvements. Overall impact includes expanded asset support, faster development feedback loops, and a more efficient CI pipeline. Technologies/skills demonstrated include JavaScript/TypeScript development, API integration patterns, transaction lifecycle handling, ESLint tooling, and CI/configuration.
