Git Source Inherits: RulesEngineClient Author: @mpetersoCode55, @ShaneDuncan602, @TJ-Everett, @VoR0220 This contract is intended to be inherited and implemented by ERC20 token contracts requiring Rules Engine integration. Abstract contract containing modifiers and functions for integrating ERC20 token operations with the Rules Engine. This contract provides policy checks for mint, transfer, and transferFrom operations, both before and after execution.

​
Functions

​
checksPoliciesERC20TransferBefore

Modifier for checking policies before executing the transfer function. Calls the _checksPoliciesERC20Transfer function to evaluate policies. 
modifier checksPoliciesERC20TransferBefore(

    uint256 value,
    uint256 balanceFrom,
    uint256 balanceTo,
    uint256 blockTime
);
Parameters
NameTypeDescription
toaddressThe receiving address.
valueuint256The amount to transfer.
balanceFromuint256The sender’s balance before the transfer.
balanceTouint256The receiver’s balance before the transfer.
blockTimeuint256The current block timestamp.

​
checksPoliciesERC20TransferAfter

Modifier for checking policies after executing the transfer function. Calls the _checksPoliciesERC20Transfer function to evaluate policies. 
modifier checksPoliciesERC20TransferAfter(
    address to,
    uint256 value,
    uint256 balanceFrom,
    uint256 balanceTo,
    uint256 blockTime
);
Parameters
NameTypeDescription
toaddressThe receiving address.
valueuint256The amount to transfer.
balanceFromuint256The sender’s balance after the transfer.

​
checksPoliciesERC20TransferFromBefore

Modifier for checking policies before executing the transferFrom function. Calls the _checksPoliciesERC20TransferFrom function to evaluate policies. 
modifier checksPoliciesERC20TransferFromBefore(
    address from,

    uint256 value,
    uint256 balanceFrom,
    uint256 balanceTo,
    uint256 blockTime
);
Parameters
