deduplicate Array.from(toBytes...) and more cosmetic improvements

[bh2smith]

User description

Closes #82

We use toPayload on Adapter.sign so that we are only constructing payloads in one singular place.

Also found a few other places (naming conventions) that could be cleanedup/improved.

PR Type

enhancement, bug fix

---

Description

• Refactored toPayload function to handle both Hex and Uint8Array types, improving payload validation.
• Removed redundant imports and deduplicated payload creation logic in NearEthAdapter.
• Enhanced logging messages for better clarity and debugging.
• Standardized variable names for consistency across the codebase.
• Updated unit tests to reflect changes in error messages.

⚡ Key issues to review Logging Consistency The logging message at line 172 introduces a new format which includes both the Near account ID and the Ethereum address. Ensure that this change is consistent with the logging strategy across the entire application, especially if logs are monitored or parsed by tools. Error Handling The function toPayload throws an error for invalid input lengths. It's crucial to ensure that all calls to toPayload properly handle this exception to avoid runtime errors. Functionality Change The sign function now uses toPayload for payload processing instead of the previous manual conversion and array creation. This change should be thoroughly tested to ensure that the behavior of signing remains consistent.

PR Code Suggestions ✨

Category	Suggestion	Score
Possible bug	Add null checks to prevent potential runtime errors in the toPayload function The toPayload function throws an error for invalid byte length but does not handle the case where toBytes might return an undefined or null value. This can lead to a runtime error when trying to access the length property. Add a null check before accessing the length property. src/utils/transaction.ts [15-18] const bytes = isBytes(msgHash) ? msgHash : toBytes(msgHash); -if (bytes.length !== 32) { - throw new Error(`Payload must have 32 bytes: ${msgHash}`); +if (!bytes || bytes.length !== 32) { + throw new Error(`Payload must have 32 bytes and be a valid byte array: ${msgHash}`); } Suggestion importance[1-10]: 8 Why: Adding null checks enhances the robustness of the toPayload function, preventing potential runtime errors when toBytes returns an undefined or null value.	8
	Add robust input handling to the toPayload function to prevent runtime errors Ensure that the toPayload function is robust against different input types and formats. The current implementation assumes that msgHash will always be either a Hex string or a Uint8Array, but does not handle cases where msgHash might not be in the expected format. Consider adding type checks and handling unexpected input gracefully. src/chains/ethereum.ts [240] -payload: toPayload(msgHash), +payload: toPayload(msgHash) || [], Suggestion importance[1-10]: 4 Why: While adding robust input handling is generally a good practice, the suggested change (payload: toPayload(msgHash) || [],) does not actually improve the robustness of the toPayload function itself. It only adds a fallback which might mask underlying issues.	4
Maintainability	Replace direct console.log usage with a configurable logging utility Replace the direct usage of console.log with a more flexible logging framework or utility that can be configured for different environments (development, production, etc.). This allows for better control over logging levels and formats, which is crucial for production environments where too much logging can lead to performance issues and log flooding. src/chains/ethereum.ts [97] -console.log(`Requesting signature from ${this.mpcContract.accountId()}`); +logger.info(`Requesting signature from ${this.mpcContract.accountId()}`); Suggestion importance[1-10]: 7 Why: Using a logging utility instead of console.log improves maintainability and allows for better control over logging levels and formats, which is beneficial for production environments.	7
Security	Ensure comprehensive testing of the toPayload function to handle all edge cases in the signing process The method sign in the NearEthAdapter class has been modified to use toPayload for preparing the payload. However, the change from Array.from(hashToSign) to toPayload(msgHash) assumes that toPayload handles all cases correctly. It's important to ensure that toPayload is thoroughly tested to handle all edge cases, as this is critical for the security and functionality of the signing process. src/chains/ethereum.ts [240] +payload: toPayload(msgHash), - Suggestion importance[1-10]: 6 Why: Ensuring that toPayload is thoroughly tested is important for security and functionality. However, the suggestion does not provide a specific code improvement but rather a recommendation for testing.	6
