#ARK SDKs and Documentation Weekly Report

This week’s work primarily focused on the client and crypto packages, along with a minor update to the documentation site. Key tasks completed include:

• Platform SDK Package:

  • Updated CI to use Node.js version 20.18 as 20.19 causes issues with dependencies. This is a temporary downgrade until we upgrade it to work with node 22.
  • Fixed the outgoing tab labeling issue where, in single view in Vault, selecting the Outgoing tab could incorrectly display transactions as incoming instead of outgoing.
  • Added support for signing all transactions using Ledger hardware wallet addresses in combination with the Ethereum Ledger app.
  • Refactored Ledger public key reading by exposing a pageSize prop on the Ledger scan method for better control. Improved performance when fetching public keys and added a retry mechanism to handle “device busy” errors.

• Python Client Package:

  • Added the receipts API endpoint and a configuration endpoint for the transactions API, while removing the old transaction endpoints.
  • Refactored the delegates method arguments by updating the delegates.blocks and delegates.voters endpoints for consistency with other SDKs.
  • Renamed wallet transaction methods to align with naming conventions used in other SDKs.
  • Refactored the blocks transactions endpoint to support wildcard arguments.
  • Added the EVM API endpoint and included missing with_endpoint('api') references for several endpoints. This prevents the issue where EVM or create transaction calls could cause subsequent calls (like Blocks.all() or Votes.all()) to be performed on the wrong API.
  • Added a coverage threshold to the test workflow for the Python client, ensuring it fails if coverage falls below 100%. Also addressed any missing coverage in the tests.

• Python Crypto Package:

  • Removed the get_bytes method from AbstractTransaction as it duplicated the functionality of the serialize method, making it redundant.
  • Added a method to the PrivateKey class to create a private key from a WIF, ensuring consistency across SDKs.
  • Refactored message signing by removing the original PrivateKey#sign method and renaming the sign_compact method. Also removed the Keccak hasher method, as it’s now possible to pass in a hashed message, skipping the hasher on CoinCurve’s side.

• TypeScript Crypto Package

  • Added additional unit converter tests to improve handling of larger numbers, ensuring accurate conversions and preventing potential overflow or inaccuracies.
  • Refactored transaction types coverage by adding tests to improve coverage and removing unused methods.
  • Added tests for the Network configuration file to ensure proper handling of network-related settings and functionality.
  • Refactored the code coverage for Serializer and Builders.
  • Set up a formatting workflow to run Linter and Prettier on PRs, ensuring consistent code formatting and resolving issues with mixed tabs and spaces.

• TypeScript Client Package:

  • Fixed the create transaction type by adjusting it to string[], as it now correctly expects an array of hex strings instead of a single string.
  • Refactored the blocks.transactions client endpoint to align with other SDKs by adjusting the accepted arguments to match the consistent format of blockId, page, and limit, ensuring uniformity across packages.
  • Updated the pnpm version in the workflows to ensure compatibility with the latest features and improvements.
  • Refactored the delegates method arguments and fixed a type issue with the voters method, where it was previously incorrectly set to votes.
  • Renamed the wallet transaction methods to match other SDKs by updating transactionsSent to sentTransactions and transactionsReceived to receivedTransactions, ensuring consistency across platforms.
  • Refactored the transactions API by adding a new configuration endpoint and removing the old transaction endpoints.
  • Refactored the code by renaming show methods to get for consistency and clarity, following standard naming conventions.

• PHP Crypto Package:

  • Removed the getBytes method from AbstractTransaction, as it duplicated the functionality of the serialize method and was no longer necessary.
  • Updated the message signing and verification process by removing support for backwards compatibility, including the v1/v2 message fixtures and the publickey/signatory JSON keys. The new signatures are not backward compatible and have been streamlined to reflect the updated signing mechanism.
  • Refactored the PHP test suite to use Pest syntax, aligning with ARKScan’s testing style. Replaced class-based tests with the it('should...') format.

• PHP Client Package:

  • Removed the types, fees, and schema endpoints from the Transactions API, as they are no longer relevant or needed in the updated implementation.
  • Renamed show methods to get in the client to align with common naming conventions and improve consistency across the codebase.

• Documentation Site:

  • Updated client examples for Python, PHP, and TypeScript packages to ensure consistency and accuracy.
  • Updated the SDK crypto documentation site with the latest changes to the Python crypto package.

Next week, our focus remains on bringing up the compatibility of Mainsail EVM across all client and crypto packages, as well as updating the documentation site.

#ARK Vault Weekly Update

We’ve been continuing to work on feedback from the internal testing team, addressing reported issues, making additional design updates, and implementing Ledger HW support. Work completed included:

• Removed all references to PortfolioBreakdown, as the new design no longer includes a breakdown feature.
• Updated the upload avatar component to match the new design. Since avatars are now square, removed the circular cutout from the image preview.
• Updated profile, settings, and portfolio domain tests to use the Mainsail network, ensuring consistency across all test suites.
• Adjusted the radio button size on the side panel to match the checkboxes in “multi view”.
• Updated the side panel behavior to prevent the hover state from appearing when an address is selected for deletion, maintaining a consistent border style.
• Fixed an issue on the Votes page where clicking the Import/Create buttons in an empty profile redirected to the main page instead of triggering the intended import/create action.
• Updated the exchange page design to align with the votes and contact pages, incorporating the same header icon styling for consistency across the application.
• Fixed extra padding in the contacts page header, ensuring alignment with the votes page for a consistent layout.
• Fixed an issue by adding a new useEffect to clear the alias when the address is cleared in the multipayments form. This ensures the alias resets properly, as the clearFields method in the parent component does not handle alias input.
• Ensured that votes are synced when updating the profile and selected address on the Votes page.
• Added a hover state to the “Back” button on the side panel address selection when on the “Manage” page.
• Refactored the useTabs hook to support a disabled prop, and added new class names and styles for tabs and tab buttons to handle disabled states. Tabs on the side panel are now disabled when entering manage mode to prevent interaction.
• Ensured that an address is displayed as selected in the address panel’s single view if the previously selected address is deleted.
• Updated the vote and wallet domain tests to use the Mainsail network, ensuring consistency with the updated network configuration.
• Moved the psdk SDK helpers to an internal lib folder, transferring only the methods used in Vault along with their internal dependencies (which are not currently exported at the root level).
• Updated CI workflows to run on pnpm 10, ensuring compatibility with the latest version and taking advantage of its new features.
• Fixed the scan modal issue by moving the navbar out of the div with margin, allowing it to cover the entire page as intended.
• Fixed the hover state for the address row component in the side panel when entering deletion mode, ensuring consistent behavior during interactions.
• Added support for signing all transactions from a Ledger address, including transactions sent from subsequent derived addresses, ensuring full functionality with Ledger hardware wallets.
• Removed unused components and their respective tests to streamline the codebase and improve maintainability.

Next week, we’ll continue addressing reported issues and finalize Ledger HW support for Mainsail EVM as we near full support for Mainsail EVM functions.

#Mainsail Weekly Report

This week, our focus has been on improving overall EVM performance, updating packages, and implementing various fixes. Work completed includes:

• A separate EVM instance was used for JSON RPC actions.
• Updated EVM Rust packages to the latest version.
• Added support for multiple pending commits in EVM.
• Internal Mainsail transaction fields were renamed to match the EVM structure.
• Improved EVM performance by removing unnecessary clones of state_hash and logs_bloom.

Next week, we’ll work on renaming fields for the public HTTP API and adding support for pnpm v10.
