and removed request for
a team
WalkthroughThe recent changes enhance EIP-712 compatibility and improve Ledger transaction processing in the Cosmos SDK. Significant updates include new functions for creating EIP-712 domains and types, alongside robust testing frameworks for validating these features. Configuration files have been optimized for better change detection and spell-checking. Overall, these enhancements strengthen the integration between Cosmos and Ethereum, improving interoperability and transaction handling. Changes

35-87: Add detailed comments for better readability.While the function is clear, adding more comments explaining the purpose of each section would improve readability.
65-65: Consider handling the removal oftimeout_heightmore explicitly.The comment mentions that
timeout_heightwas removed because it was not getting filled with the legacyTx. It might be helpful to log this removal or handle it more explicitly.
115-128: Add comments to explain the logic.Adding comments to explain the purpose of each step in the function would improve readability and maintainability.
185-193: Handle unsupported JSON types more explicitly.The function currently ignores unsupported JSON types (e.g., nested arrays). Consider logging or handling these cases more explicitly.
