[bh2smith]

User description

Note that this still needs UserOperation v0.6 support (all other chains apart from sepolia still use v0.6).

Description

• Added a new example script (load-manager.ts) to load transaction managers for multiple chain IDs.
• Updated send-tx.ts example script to use PIMLICO_KEY instead of ERC4337_BUNDLER_URL.
• Enhanced ContractSuite to handle fallback versions for contract deployment.
• Introduced managerForChainId function in TransactionManager for multi-chain support.
• Renamed safeAddress to address in TransactionManager for consistency.
• Updated .env.sample and README.md to reflect the change from ERC4337_BUNDLER_URL to PIMLICO_KEY.

⚡ Key issues to review Error Handling The script lacks error handling for the asynchronous operations within the main function, particularly for the managerForChainId calls. Consider adding try-catch blocks around these operations to handle potential rejections and provide more robust error management. Method Consistency The method chainId in TransactionManager class uses parseInt on the chain ID, which is already a number. This redundant conversion could be removed for cleaner code. Fallback Logic The fallback logic in m4337Deployment function uses a hardcoded version "0.2.0" when an error occurs. This could lead to unexpected behavior if the version "0.2.0" is incompatible or unavailable. Consider implementing a more dynamic version handling or configuration approach.

PR Code Suggestions ✨

Category	Suggestion	Score
Possible bug	Add checks for undefined environment variables to prevent runtime errors Consider checking if process.env.NEAR_ACCOUNT_ID and process.env.PIMLICO_KEY are not undefined before using them. This can prevent runtime errors due to undefined environment variables. examples/load-manager.ts [12-24] +if (!process.env.NEAR_ACCOUNT_ID || !process.env.PIMLICO_KEY) { + throw new Error("NEAR_ACCOUNT_ID and PIMLICO_KEY must be defined in the environment."); +} const nearAccount = await nearAccountFromAccountId( - process.env.NEAR_ACCOUNT_ID!, + process.env.NEAR_ACCOUNT_ID, nearNetwork ); ... -await managerForChainId(nearAdapter, chainId, process.env.PIMLICO_KEY!) +await managerForChainId(nearAdapter, chainId, process.env.PIMLICO_KEY) Suggestion importance[1-10]: 9 Why: This suggestion addresses a potential runtime error by ensuring that critical environment variables are defined before they are used. This is a significant improvement for robustness.	9
Best practice	Replace process exit with error throwing for better error handling Replace the hard exit using process.exit(0) with a more graceful exit strategy, such as throwing an error or returning from the function, to allow for better error handling and cleanup. examples/send-tx.ts [64-66] console.warn( `Safe ${txManager.address} insufficiently funded to perform this transaction. Exiting...` ); -process.exit(0); // soft exit with warning! +throw new Error(`Insufficient funds for transaction on Safe ${txManager.address}`); Suggestion importance[1-10]: 8 Why: Replacing the hard exit with an error throw improves error handling and allows for better cleanup and debugging. This is a best practice and enhances the code's robustness.	8
Maintainability	Refactor the deployment function to improve code readability and separation of concerns Refactor the m4337Deployment function to separate concerns, specifically separating the error handling and deployment logic into distinct functions. src/lib/safe.ts [44-51] const m4337Deployment = async ( fn: DeploymentFunction ): Promise<ethers.Contract> => { + return handleDeploymentError(fn, provider); +}; + +async function handleDeploymentError(fn: DeploymentFunction, provider: ethers.JsonRpcProvider): Promise<ethers.Contract> { try { return await getDeployment(fn, { provider, version: "0.3.0" }); } catch (error: unknown) { console.warn((error as Error).message, "using v0.2.0"); return getDeployment(fn, { provider, version: "0.2.0" }); } -}; +} Suggestion importance[1-10]: 7 Why: This refactoring improves code readability and maintainability by separating error handling from the main logic. However, it does not address any functional issues.	7
	Improve variable naming for clarity Use a more descriptive variable name than pimlicoKey to clarify its purpose, such as apiAccessKey. src/tx-manager.ts [13] -pimlicoKey: string +apiAccessKey: string Suggestion importance[1-10]: 6 Why: While the suggestion to use a more descriptive variable name improves code readability and maintainability, it is a minor change and does not address any functional issues.	6
