Welcome to this week’s Weekly Development Report, highlighting continued progress across the ecosystem. The ARK Scan team focused on optimizing transaction and block data loading, significantly improving responsiveness across key views through caching and query efficiency enhancements. The ARK SDKs and Documentation team expanded transaction support in the TypeScript Crypto package and aligned the repository with shared AI-driven development standards. The ARK Vault team improved validator flows, refined transaction handling and UX, and removed legacy multisignature functionality to reduce complexity and improve reliability. Meanwhile, the Mainsail team concentrated on substantially increasing unit test coverage across core modules, strengthening system stability and confidence for future development.

ARK Scan Weekly Report
This week we focused on improving performance across core areas of ARK Scan, particularly around transaction and block data loading.
We refactored transaction and block count handling on the homepage to address slow loading times. Previously, fetching transaction counts, especially for pagination, introduced significant delays (up to ~400–500ms per request). This has now been optimized by reducing unnecessary model instantiation and introducing short-term caching for counts, updated on a minute basis. As a result, overall page responsiveness has improved noticeably.
In addition, we implemented broader performance optimizations for transactions and blocks across the application. This includes improvements to query efficiency and data handling for the following areas:
- Home page (Blocks tab)
- Wallet page (Transactions and Blocks tabs)
- Transactions page
- Blocks page
These changes reduce load times and improve the responsiveness of data-heavy views, especially under higher data volumes.
Next week, we will continue focusing on performance optimizations across the application, identifying additional bottlenecks and refining query efficiency. We’ll also monitor real-world performance, address any regressions, and further improve caching strategies where beneficial.
ARK SDKs & Documentation Site Weekly Report
This week we focused on extending transaction support in the TypeScript Crypto package and aligning the repository with shared development standards.
In the TypeScript Crypto package, we added a transaction data encoder for both batchTransfer and approve transaction types. This enables proper encoding of transaction payloads for these operations, ensuring they can be constructed, signed, and broadcast correctly within the ecosystem.
We also installed the Ardent AI conventions, bringing the repository in line with shared tooling and standardized development practices across projects.
Next week, we will continue working on SDK packages to expand feature support and maintain consistency across languages. We’ll also ensure that all newly introduced functionality is properly documented in the documentation site, with clear examples and usage guidelines for developers.
ARK Vault Weekly Report
This week we focused on improving reliability in validator flows, cleaning up legacy functionality, and refining transaction handling and UX across ARK Vault.
We resolved several issues in the validator registration flow, including fixing alignment problems in the review step, improving passphrase validation by switching to a BIP39-compatible method that correctly supports non-English mnemonics, and updating the input label for better clarity.
We also improved transaction error handling by removing duplicate error messages. Known errors now display the exact server response, while unknown errors fall back to a generic message, resulting in clearer and more consistent feedback for users.
Several UI and UX improvements were made, including fixing text overflow issues in the server status dropdown to ensure proper wrapping and readability.
In the Ledger migration flow, we fixed an issue where transactions could fail due to insufficient funds. This was caused by not accounting for transaction fees in the migration amount calculation. A dust buffer is now included to ensure successful transaction submission.
We also refactored Ledger derivation logic to use account index–based derivation, simplifying the model and aligning it with expected usage patterns.
Next week, we will continue testing ARK Vault to identify and resolve any remaining issues, with a focus on stability and edge cases. We’ll also further refine transaction flows, improve UX where needed, and continue aligning the application with ongoing Mainsail integration efforts.
Mainsail Weekly Report
This week, we focused on significantly expanding unit test coverage and improving overall reliability across multiple core packages.
We increased test coverage and addressed related fixes across a wide range of modules, including configuration-generator, API, and several API sub-packages such as api-database, api-common, api-transaction-pool, api-evm, api-http, and api-sync. These improvements help ensure more consistent behavior, better regression protection, and increased confidence when making changes across the codebase.
In addition, we expanded coverage and resolved issues within the evm-consensus module, further strengthening the correctness and stability of consensus-related logic.
Overall, this effort improves code quality across critical system components and lays a stronger foundation for future development and refactoring.
Next week, we will continue expanding unit test coverage across remaining areas, address any gaps identified during testing, and implement further improvements to enhance stability and maintainability.
