MyCut

Summary

Some informational findings in Pot.sol:

1. Error: Pot__InsufficientFunds();
   This error is declared but not used anywhere in the contract.

2. Variables should be immutable: i_players and i_rewards should be marked as immutable since they do not change after initialization. They are already prefixed with i_, which suggests immutability, but they are not actually declared as such.

   address[] private i_players;

   uint256[] private i_rewards;

3. Unused commented line in the constructor: There is a commented-out line in the constructor that is not being used and should be removed for clarity.

   // i_token.transfer(address(this), i_totalRewards);

4. Magic number in closePot: The value 90 days is a magic number and should be replaced with a named constant for better readability and maintainability.

5. Incorrect formula for managerCutPercent: The current formula for calculating the manager's cut only works correctly when managerCutPercent is 10%. It will not produce correct results for other values.

Recommendations

1. Delete the unused error declaration:

   Remove the Pot__InsufficientFunds(); line if it's not being used in the contract.

2. Make variables immutable:

   Since i_players and i_rewards do not change after they are initialized, mark them as immutable:

   - address[] private i_players;

   - uint256[] private i_rewards;

   + address[] private immutable i_players;

   + uint256[] private immutable i_rewards;

3. Remove the unused commented line:

   Delete the line // i_token.transfer(address(this), i_totalRewards); from the constructor to keep the code clean and readable.

4. Use a named constant instead of a magic number:

   Replace 90 days with a named constant to make the code more understandable:

   uint32 private constant DEADLINE = 90 days;

5. Correct the formula for the manager's cut:

   Update the formula to correctly calculate the manager's cut for any percentage, not just 10%:

   - uint256 managerCut = remainingRewards / managerCutPercent;

   + uint256 managerCut = (remainingRewards * managerCutPercent) / 100;

   This formula ensures that the manager's cut is correctly calculated as a percentage of the remaining unclaimed rewards.
