Summary

Magic numbers for "gasLimit" storage variable inside the constructor of "KittyBridge.sol"

Vulnerability Details

As we know magic numbers are hardly against best practices, so usage of constants is highly encouraged, this way we will have
a constant as one source of a truth for every usage of the variable and also will save gas for the protocol since constants in Solidity are typed in the bytecode directly and do not get stored in the storage.

Impact

Low, since it's gas related issue and would be a big impact for example, if an extra zero is being added to the variable.

Tools Used

Slither

Recommendations

Use constant such as:
uint256 internal constant GAS_LIMIT = 400000;
