#ARK Scan Weekly Report

This week, several improvements and fixes were made across various components to enhance test coverage, improve reliability, and optimize performance. Below is a summary of the key work completed:

• Added coverage for cache blocks, transaction method, validator registration, has method trait, has payload, and has voters trait to improve reliability and test completeness.
• Increased test coverage for transaction-related models, including transaction view model, transaction view model receipt, and transaction view model voted tests.
• Expanded coverage for state model and models transaction components, ensuring comprehensive testing of core logic.
• Improved dto memory wallet test coverage to prevent potential issues and edge cases.
• Addressed flakiness in cache address statistics tests, stabilizing performance and ensuring consistent results.
• Enhanced blockchain network service coverage to address potential gaps in test scenarios.
• Corrected the ‘All Time Prices’ display in statistics, ensuring accurate data representation.
• Improved coverage for cache annual statistics to ensure consistency in long-term data handling.
• Updated GitHub Actions to use phpunit cache, reducing build times and improving efficiency.

Next week, we will continue implementing additional improvements and making necessary changes to ensure accurate and comprehensive data display for the Mainsail EVM network.

#ARK SDKs and Docs Weekly Report

This week, we focused on making several adjustments to the Platform SDK. The completed work includes:

• Updated PSDK to provide fee options with gas price and gas limit.
• Refactored formatUnits and parseUnits helpers to return a BigNumber instead of a string value.
• Updated transaction logic to use gasLimit and gasPrice when sending transfer transactions.

Next week, we will continue refining the PSDK and make further progress on documentation updates.

#ARK Vault Weekly Report

This week, we continued working on the Mainsail EVM integration and the necessary updates. The completed work includes:

• Implemented support for the updated Mainsail fee structure and logic.
• Refactored review steps for Send and Vote transactions, updating their designs.
• Updated username registration transaction details to display the username and added a new unit test for this feature.
• Removed icons for unused transaction types.
• Renamed the “Transaction Type” section to “Action” and the “Category” subsection to “Method.”
• Displayed the delegate’s address when no username is available.
• Removed @emotion dependencies and babel macros.
• Removed font ligatures from the Address Link and Labels components to prevent the “x” from appearing misaligned when numbers are present in the address.

Next week, we will continue working on Mainsail changes and additional flow updates required for Mainsail EVM.

#Mainsail Weekly Report

Work on Mainsail has started with fixes to the API and pool, along with progress on additional API features. Most notably:

• Fixed ORDER BY logic for receipts in the HTTP API.
• Added log callback to support sending logs from the Rust process to the JS process, enabling integration with the default Mainsail logger.
• Fixed end-to-end tests by using the correct glibc library.
• Fixed transaction sorting in the transaction pool service where transactions are now sorted by sender’s nonce and gas.
• Sorted validators by voteBalance (descending) and address (ascending) in the consensus contract.
• Implemented new EVM JSON RPC endpoints: eth_getTransactionByHash, eth_getTransactionByBlockHashAndIndex, and eth_getTransactionByBlockNumberAndIndex.

Next week, we’ll continue improving the JSON RPC and transaction schemas, as well as enhancing EVM error handling.
