PR Code Suggestions ✨

Category	Suggestion	Score
Security	Add address validation in the isContract function to enhance security Ensure that the address parameter in isContract function is validated or sanitized to prevent potential security vulnerabilities, such as injection attacks. src/util.ts [41-43] export async function isContract( address: Address, chainId: number ): Promise<boolean> { + if (!ethers.utils.isAddress(address)) throw new Error("Invalid address"); Suggestion importance[1-10]: 10 Why: Adding validation for the address parameter is crucial for preventing potential security vulnerabilities. This suggestion significantly enhances the security of the function.	10
Best practice	Use nullish coalescing for defaulting to avoid falsy value issues Consider using nullish coalescing (??) instead of logical OR (||) for default values to avoid unexpected falsy evaluations. This is particularly important for numeric values where 0 is a valid value but is falsy in JavaScript. src/util.ts [29-30] -toHex(BigInt(data.paymasterVerificationGasLimit || 0n), { size: 16 }), -toHex(BigInt(data.paymasterPostOpGasLimit || 0n), { size: 16 }), +toHex(BigInt(data.paymasterVerificationGasLimit ?? 0n), { size: 16 }), +toHex(BigInt(data.paymasterPostOpGasLimit ?? 0n), { size: 16 }), Suggestion importance[1-10]: 8 Why: This suggestion improves the robustness of the code by ensuring that valid numeric values like 0 are not mistakenly replaced by default values. It addresses a potential bug and enhances code reliability.	8
Maintainability	Refactor tests to use parameterized inputs for cleaner code Refactor the repeated isContract test cases into a single test with parameterized inputs to reduce redundancy and improve maintainability. tests/utils.spec.ts [73-76] -expect(isContract(zeroAddress, chainId)).toBe(false); -expect( - isContract("0x9008D19f58AAbD9eD0D60971565AA8510560ab41", chainId) -).toBe(true); +const testCases = [ + { address: zeroAddress, expected: false }, + { address: "0x9008D19f58AAbD9eD0D60971565AA8510560ab41", expected: true } +]; +testCases.forEach(({ address, expected }) => + expect(isContract(address, chainId)).toBe(expected) +); Suggestion importance[1-10]: 7 Why: Refactoring the test cases to use parameterized inputs reduces redundancy and improves maintainability. This suggestion enhances the readability and maintainability of the test code.	7
Enhancement	Use a structured logger for better log management Replace the generic console.log with a more structured logging approach, such as using a dedicated logger that can handle different levels and formats of logs. examples/send-tx.ts [22] -console.log("Safe Deployed:", deployed); +logger.info("Safe Deployed:", deployed); Suggestion importance[1-10]: 6 Why: While using a structured logger is a good practice for better log management and scalability, it is not critical for the functionality of the code. This suggestion improves code quality but is not essential.	6
