⚡ Key issues to review Error Handling Logic Returning true in the catch block (line 19) might mask underlying issues. Consider logging the error or returning false to indicate failure.

PR Code Suggestions ✨

Category	Suggestion	Score
Possible bug	Change the return value in the catch block to false to avoid incorrect positive confirmations of account existence In the catch block, returning true when an error occurs might lead to incorrect behavior if the account does not exist but an error prevented the check. It's safer to return false to indicate that the account's existence could not be verified. packages/rpc/src/methods/account.ts [20] } catch (error) { - return true; + return false; Suggestion importance[1-10]: 9 Why: Returning true in the catch block can lead to incorrect assumptions about account existence when an error occurs. Changing it to false is a critical fix to prevent false positives.	9
Enhancement	Add error logging in the catch block to aid in debugging and error tracking Consider adding logging for the error inside the catch block. This will help in debugging and understanding why the error occurred, which is crucial for maintaining robust error handling in production environments. packages/rpc/src/methods/account.ts [20] } catch (error) { - return true; + console.error('Failed to check account existence:', error); + return false; Suggestion importance[1-10]: 8 Why: Adding logging in the catch block is a valuable enhancement for debugging and maintaining robust error handling, especially in production environments.	8
	Enhance the error checking logic to handle potential changes in the response object structure The res?.error check might not be sufficient if the res object structure changes or if error is not the only key indicating an error. It's recommended to check for both the presence of an error key and the absence of expected data. packages/rpc/src/methods/account.ts [16] -if (res?.error) { +if (res?.error || !res?.result) { return false; Suggestion importance[1-10]: 7 Why: Improving the error checking logic by considering both the presence of an error and the absence of expected data increases robustness against changes in the response structure.	7
Maintainability	Simplify parameter destructuring by using the object directly in the function signature The destructuring of the AccountParams type in the function parameter can be simplified by directly using the properties in the callNearRpc call, reducing redundancy and improving code readability. packages/rpc/src/methods/account.ts [4] -export const accountExists = async ({ accountId, rpcUrl }: AccountParams): Promise<boolean> => { +export const accountExists = async (params: AccountParams): Promise<boolean> => { + const { accountId, rpcUrl } = params; Suggestion importance[1-10]: 6 Why: Simplifying parameter destructuring improves code readability and maintainability, though it is a minor enhancement compared to functional changes.	6
