1-6: Overall structure improvement and security reminderThe reorganization of the
.env.examplefile improves readability by grouping related variables together. This is a good practice for maintaining clear and organized configuration files.As a general reminder, please ensure that:
- All sensitive information (API keys, private keys, mnemonics) are properly handled in the actual code.
- There are clear instructions in the project documentation on how to set up and use these environment variables.
- Consider using a secrets management system for production deployments to enhance security.

16-26: LGTM: Improved environment variable checksThe updated checks for required environment variables and the new check for authentication methods (MNEMONIC or PRIVATE_KEY) are well-implemented. They provide clear warnings and ensure necessary configuration for deployment.
Consider combining the two checks into a single conditional statement to reduce code duplication:
if (!INFURA_KEY || !ETHERSCAN_API_KEY || (!MNEMONIC && !PRIVATE_KEY)) { console.warn( "Please set the INFURA_KEY, ETHERSCAN_API_KEY, and either MNEMONIC or PRIVATE_KEY environment variables to deploy and verify contracts. If neither MNEMONIC nor PRIVATE_KEY is set, a default mnemonic will be used." ); }This suggestion consolidates the warnings and reduces the number of console.warn calls.
59-64: LGTM: Flexible account configuration in getChainConfigThe implementation of flexible account configuration in the
getChainConfigfunction is well done. It correctly supports both private key and mnemonic-based setups, aligning with the PR objective.For improved type safety, consider explicitly typing the
accountsvariable:let accounts: string[] | { mnemonic: string }; if (PRIVATE_KEY) { accounts = [PRIVATE_KEY]; } else { accounts = { mnemonic }; }This change ensures that the
accountsvariable always has the correct type, which can help prevent potential type-related issues in the future.

2-2: LGTM: Addition of ETHERSCAN_API_KEYThe addition of
ETHERSCAN_API_KEYis a good practice. It suggests that contract verification on Etherscan might be part of the deployment process, which enhances transparency and allows users to interact with verified contracts.
4-6: Ensure secure handling of private keys and mnemonicsThe addition of
PRIVATE_KEYandMNEMONICvariables with the comment "only one of the following should be set" is a good approach to support different key management methods. This aligns with the PR objective of allowing deployment from a specific private key.However, please ensure that:
- The code that uses these variables properly handles the mutually exclusive nature of these options.
- There are appropriate security measures in place to protect these sensitive values, such as encryption at rest and secure transmission.
- The actual
.envfile is added to.gitignoreto prevent accidental commit of sensitive information.To verify the security measures, please run the following script:

14-14: LGTM: Addition of PRIVATE_KEY environment variableThe inclusion of
PRIVATE_KEYin the environment variable destructuring aligns with the PR objective and provides flexibility in authentication methods for contract deployment.
67-67: LGTM: Simplified accounts property in getChainConfig return statementThe simplification of the
accountsproperty in thegetChainConfigfunction's return statement is correct and consistent with the new flexible account configuration.
Line range hint
14-67: Overall assessment: Well-implemented changes for flexible deployment configurationThe modifications to
hardhat.config.tssuccessfully implement the ability to deploy contracts using either a mnemonic or a specific private key. The changes are well-structured, maintain backward compatibility, and provide clear warnings when required configuration is missing.Key improvements:
- Addition of
PRIVATE_KEYsupport- Updated environment variable checks
- Flexible account configuration in
getChainConfigThese changes enhance the deployment flexibility of the project while maintaining security and ease of use. The code is clean and aligns well with the PR objectives.
