PR Description

Summary

This PR introduces two significant improvements to TestArbitrage.sol:

1. A profitRecipient address to allow profits to be directed to an account different from the contract owner.
2. A ConfigurationUpdated event to standardize and improve transparency for any future configuration changes.

Both features enhance flexibility and governance while maintaining clear auditing capabilities.

Changes

• Profit Recipient

  • Added address public profitRecipient;
  • Enables decoupling of contract ownership from profit collection.
  • Allows profits to be distributed to DAOs, treasuries, or external accounts without transferring ownership rights.

• ConfigurationUpdated Event

  • Introduced:

    event ConfigurationUpdated(
        string parameter,
        uint256 oldValue,
        uint256 newValue,
        address changedBy
    );

  • Provides a standardized way to log configuration changes.
  • Includes detailed metadata for each change:
    • parameter: Name of the updated parameter.
    • oldValue: The previous value.
    • newValue: The updated value.
    • changedBy: Address that executed the update.

• Formatting

  • Applied forge fmt to keep code style consistent.

Rationale

• Profit Flexibility
  Owners may want to separate governance (ownership) from financial beneficiaries (profit recipients). This allows scenarios where a DAO governs the contract but profits flow to a treasury wallet.

• Governance Transparency
  Clear event logs for parameter updates improve traceability and accountability, aiding both testing and production environments.

Impact

• Non-breaking change: existing contract logic remains intact.
• Profit distribution logic can now be directed independently of ownership.
• Future upgrades or configuration changes will emit consistent, auditable events.

Next Steps

• Implement functions to:
  • Update profitRecipient with appropriate access control.
  • Emit ConfigurationUpdated when profit recipient or other parameters change.
• Extend test coverage for:
  • Profit recipient assignment and updates.
  • Validation of ConfigurationUpdated event emission.
