Enhancement

send-tx.ts Simplify TransactionManager initialization in example script examples/send-tx.ts Removed nearAdapter setup from TransactionManager.create call. Added accountId, mpcContractId, and privateKey directly to TransactionManager.create call. +3/-7      tx-manager.ts Internalize nearAdapter setup in TransactionManager            src/tx-manager.ts Imported setupAdapter from near-ca. Modified TransactionManager.create to initialize nearAdapter internally. Added accountId, mpcContractId, and privateKey to TransactionManager.create parameters. +15/-4

⚡ Key issues to review Missing Error Handling The new implementation in TransactionManager.create uses Promise.all to concurrently initialize nearAdapter and safePack. However, there is no error handling for these promises. If any of these initializations fail, the error will not be handled gracefully. Dependency Concern The PR introduces a direct import from 'near-ca' which includes multiple components (NearEthAdapter, NearEthTxData, BaseTx, Network, setupAdapter). This contradicts the stated goal of the PR to contain near-ca dependencies within this project. Consider refactoring to align with the project's architectural goals.

PR Code Suggestions ✨

Category	Suggestion	Score
Possible issue	Add validation for nearAccountId and nearAccountPrivateKey to ensure they are not null or incorrectly formatted It's recommended to validate the nearAccountId and nearAccountPrivateKey before using them to create a TransactionManager. This ensures that the provided values are not null or incorrectly formatted, which could lead to runtime errors or security vulnerabilities. examples/send-tx.ts [16-19] +if (!nearAccountId || !nearAccountPrivateKey) { + throw new Error("Invalid account ID or private key."); +} const txManager = await TransactionManager.create({ accountId: nearAccountId, mpcContractId, pimlicoKey, privateKey: nearAccountPrivateKey, }); Suggestion importance[1-10]: 9 Why: This suggestion addresses a potential runtime error and security vulnerability by ensuring that critical parameters are validated before use. This is a significant improvement in terms of robustness and security.	9
	Ensure handling of the optional privateKey parameter to avoid unintended behavior The privateKey parameter in the TransactionManager.create method is optional, which could lead to unintended behavior if not handled properly. Ensure that the logic within TransactionManager.create accounts for cases where privateKey might be undefined. src/tx-manager.ts [45-51] static async create(config: { accountId: string; mpcContractId: string; pimlicoKey: string; privateKey?: string; safeSaltNonce?: string; }): Promise<TransactionManager> { + if (config.privateKey === undefined) { + console.warn("Warning: privateKey is undefined. Some operations may not be available."); + } Suggestion importance[1-10]: 8 Why: This suggestion improves the robustness of the code by handling cases where privateKey might be undefined, preventing potential unintended behavior and providing a warning to the user.	8
Possible bug	Add a check to ensure pimlicoKey exists in config before destructuring The destructuring of pimlicoKey directly from config in the create method might lead to errors if config is not properly formed. Consider adding a check to ensure config contains pimlicoKey. src/tx-manager.ts [52] +if (!config.pimlicoKey) { + throw new Error("pimlicoKey is required in the configuration."); +} const { pimlicoKey } = config; Suggestion importance[1-10]: 7 Why: This suggestion adds a necessary validation step to ensure that pimlicoKey is present in the configuration, which helps prevent runtime errors due to missing properties.	7
Security	Enhance security by encrypting the private key before use Consider using a more secure method to handle private keys instead of passing them directly in the method call. This can help prevent security risks such as leakage of sensitive information. examples/send-tx.ts [19] -privateKey: nearAccountPrivateKey, +privateKey: encryptKey(nearAccountPrivateKey), Suggestion importance[1-10]: 6 Why: While this suggestion improves security by encrypting the private key, it requires additional context about the encryptKey function and its implementation. It is a good practice but needs careful consideration and implementation.	6
