Avoiding Common Attacks

Using Specific Compiler Pragma

Used pragma solidity ^0.8.0 to indicate the lowest compiler version so as to ensure all contracts and dependencies are compiled accurately.

Proper Use of require, assert, and revert

Used require to perform validations of input parameters in functions. Used assert to validate situations that should never happen, especially after state changes. Used this towards the end of functions.

Use Modifiers Only for Validation

Used function modifiers to only perform validations of input parameters.

SWC-131 Presence of unused variables

Removed or commented out unused variables.
