LowGas optimizationFixed

`updateReward()` calls `rewardPerToken()` twice, in the function body and when executing `earned()`, we recommend to use the state variable `rewardPerTokenStored` inside `earned()` instead of calling the `rewardPerToken()`.

LowMissing validation of the number of decimals for ERC20 tokensFixed

The contract assumes tokens with 18 decimals. Based on the provided code, it is unclear whether this assumption holds.

LowNo checks if addresses are non-zeroFixed

The functions `Delegator.constructor()` and `DelegatorFactory.constructor()` do not check if arguments of type address are non-zero.
