ARK Development Report - May 30, 2025

Welcome to our latest Weekly Development Report, where we spotlight the valiant efforts of our development team. This week, the ARK Scan team addressed data issues affecting the statistics page, while updates to the documentation site were made to reflect recent changes in the TypeScript client, alongside several enhancements to the TypeScript libraries themselves. The ARK Vault team focused on a major upgrade to Tailwind CSS v4, updated various minor dependencies, and implemented fixes based on internal testing. Meanwhile, the Mainsail team worked on resolving transaction-related issues and continued improving the test coverage.

#Development Activity Summary (May 23 – May 30, 2025)

Below is a breakdown of the total number of merged commits and contributing authors by project, highlighting development activity from May 23, 2025, to May 30, 2025.

During this period, the team maintained strong productivity and engagement, delivering 84 merged commits across all projects.

It’s important to note that weekly commit counts and project-specific data may fluctuate based on the focus of internal sprints, evolving objectives, and the complexity of tasks undertaken.

#ARK Scan Weekly Report

This week, we worked on fixing data issues on the statistics page. Work completed included:

• Fixed an issue where all-time transaction fees in the statistics view were calculated or displayed incorrectly. The fix ensures that fee values are now aggregated correctly with proper decimal handling, so the displayed totals accurately reflect the actual on-chain data.
• Fixed an issue where daily transaction averages were not updating correctly, often showing zero despite active network activity. Adjusted the logic to ensure consistent updates now that automated scripts are running. Also improved the readability of the multipayment transaction query.

Next week, we will continue working on any issues reported by internal testing.

#ARK SDKs & Docs Weekly Report

This week, we made updates to the documentation site to reflect recent changes to the TypeScript client and made several additions to the TypeScript libraries. Work completed included:

• Documentation Site:
  • Updated all TypeScript import references from @arkecosystem/crypto and @arkecosystem/client to @arkecosystem/typescript-crypto and @arkecosystem/typescript-client to reflect the current package structure.
  • Updated the TypeScript examples in the documentation to include wrapper functions around await calls. This helps make the examples clearer and more accessible for developers who may not be familiar with using await at the top level.
• TypeScript Client:
  • Implemented the eth_estimateGas JSON-RPC method to dynamically determine gas estimates instead of using hardcoded values. This method is now used wherever gas fees are calculated, providing a more accurate default value to display to users. A corresponding unit test has also been added to ensure reliability.
  • Adjusted the ethCall method to take the full request body as a parameter instead of fixed arguments. This allows support for additional EVM JSON-RPC methods beyond just eth_call, increasing flexibility and compatibility with other EVM interactions.

Next week, we will continue working on improvements to the libraries and begin preparing the documentation site for the Public Mainsail Devnet.

#ARK Vault Weekly Report

This week, we focused on a major update to Tailwind CSS v4. In addition, we made several updates to minor dependencies and implemented various fixes based on internal testing. Highlights of the work completed include:

• ARK Vault has been updated to use Tailwind CSS v4, along with several related configuration and codebase changes to ensure full compatibility and functionality:
  • PostCSS configuration has been updated to use the new @tailwindcss/postcss package as required by Tailwind v4.
  • Vite and Vitest configurations have been adjusted to support the updated Tailwind setup and its dependencies.
  • Multiple components have been refactored to align with the new class name structure introduced in Tailwind v4.
  • Unit tests and snapshot files have been updated to reflect changes in class names and component structure.
  • The format workflow has been disabled temporarily to prevent issues with the new Tailwind class name syntax.
• Updated all dependencies to their latest patch versions to ensure compatibility and incorporate minor bug fixes without introducing breaking changes.
• Performed additional cleanup and removed unused code. Replaced legacy unit formatting with the UnitConverter from typescript-crypto. Removed remaining coin-related references such as wallet.coinId() and wallets.findByCoinWithNetwork(). Also updated the last occurrences of delegate references to validator for consistency across the codebase.
• Implemented the eth_estimateGas call for transaction sending. This replaces hardcoded gas values with dynamically fetched estimates using the eth_estimateGas JSON-RPC method. The value returned is now used as the default gas value during fee calculations, ensuring more accurate and network-aware transaction fee handling.
• Updated all test-related dependencies including Vitest, MSW, and Testing Library. Removed the jest-when package and refactored affected tests to simplify and reduce dependency overhead.
• Updated dependencies to their latest minor versions. Removed rollup since Vite already includes it internally. Dropped type-fest as its utility was replaced by TypeScript’s built-in Omit<>. Removed query-string in favor of using URLSearchParams for query handling. ESLint and Vite dependencies were also bumped to their latest minor versions.
• Replaced all instances of “delegate” with “validator” across unit tests, component props, interfaces, and types to align with the updated API. Updated test-ids, method names, and test cases accordingly. The Mainsail manifest and relevant translations were also revised to reflect this terminology change. Removed outdated snapshots and unused components as part of the cleanup.
• The ValidatorStatus component has been refactored to include group-hover styles, resolving the issue of the label blending into the background when hovering over the row.
• Fixed an issue with sending transfer transactions involving large amounts. The advanced fee adjustment buttons now use min and max values from the API. A bug with the fee mode switch has been resolved—when switching from advanced to simple view, the estimated fee is correctly retained. gasPrice and gasLimit are now handled as BigNumber instead of plain numbers, and the related types have been updated accordingly. Unit tests were added and fixed to cover these changes, and gas limit defaults have been restored.
• Integrated knip with a customized configuration to detect unused code and files using pnpm unused. This setup serves as a proof of concept to validate its accuracy in identifying truly unused parts of the codebase.

Next week, we will continue resolving any remaining issues, cleaning up unused parts of the codebase, and working to make the ARK Vault codebase even more streamlined and efficient.

#Mainsail Weekly Report

This week, we focused on resolving reported issues related to transactions and enhancing our testing infrastructure. Most notably:

• Fixed an issue where the Transaction Pool was not expiring transactions under specific conditions.
• Resolved a problem with transaction rebroadcasting that affected very large transactions.
• Improved the stability of end-to-end (E2E) client tests.
• Restored functional consensus tests.
• Updated unit tests for @mainsail/crypto-messages to ensure accuracy and coverage.

Next week, our attention will shift toward preparations for the Internal Devnet, which serves as a precursor to the upcoming Public Devnet. We will focus on integrating validator fees into the Consensus contract, performing snapshot testing for the V3 Devnet, and enhancing overall test coverage.
